Funny how things work out.Six months ago I couldn't find a C9 if my life depended on it.I made posts looking for either a C9 or C91 on this forum & 2 others that I belong to & had to wait & wait.I bought my 1st C9 from a member here,but it's going to take quite a bit of work to get that one going again (a long term project).I unexpectedly found my 2nd C9 on Ebay at a very reasonable price & it didn't take much to get it running. I was contacted by a young gent in southern Indiana earlier this week about a post I made looking for a C9 on another forum.I'd actually forgotten about that post.The saw is on it's way now & is supposed to be delivered on Mon.It'll need some parts replaced,but is supposed to have good compression,& comes with a 27 in.bar. In 6 mo.I went from zero C9's to 3 C9's.Lol

I got the C9 today & was impressed with the shape of the piston & cylinder.Unfortunately it doesn't have any spark & had the totally wrong spark plug in it - a Champion CJ14,way too hot of a plug.It's a stricktly red colored saw & has no vinyl grip on the front handle.My guess is it's an early C9,I'll get the ser.# here tomorrow.I took the recoil off to clean it out,it was full of old crud,& one of the pawls fell out.One of the keepers & the small spring are gone.Other than that I can't complain for $50.I'll get pics on here tomorrow as well.

After working half the day on tearing the flywheel off & getting the points & condenser out & putting a new condenser & cleaning up the black points & reinstalling in 90 + degree heat wave,It still has no spark! I'll check the switch tomorrow.The first thing I did was replace the spark plug.

I pulled the switch out & disconnected it & found that the coil wire kept coming out further than normal.I tested for spark & had good spark,but in the process of trying to put the switch back in I found the culprit.Someone had spliced on a section of coil wire onto the existing coil wire & used electrical tape on it.After time & heat from the engine the tape came half undone & was shorting out.I don't know if I can get a replacement lead or not.If not I might have to go with an aftermarket coil that LRB sells.I know Rowdy had some issues with one of those units on his C91.

I did have some clearance issues with mine, it was easily remedied but still frustrating to have to modify a brand new part.
I purchased the lead separately from the coil, so I am sure you can get them. The one I bought for my C-91 was a cross reference of the original part but ended up being 5mm, whereas I believe the original was 7mm. Since the coil was also new it screwed in nice and tight, but you may not be so lucky with the original coil. A *good* parts store should have the solid core plug wire in bulk, may be worth checking into.

I did manage to do what is called a "Western Union splice".This is where 2 coil wires are spliced together & a section of fuel line is pulled over the splice.Ideally the splice should be soldered.This does work well in a pinch.I have good spark,but I can't get the saw to fire at all.I'm going to check compression next.It felt like there should've been enough compression for the saw to fire.I might try another plug too,I did have a new NGK in the saw.I've never had a bad NGK,but there's a first time for everything. Edit:I noticed that the original coil wire on the saw was not solid core,nor was it copper.It was braided & it was silver in color.Also,where it screws into the coil it had a special pressed on attachment that's supposed to make for a good connection in the coil.The wire doesn't actually screw into the coil that I could see,but rather is just pressed in.

Most fuel line is conductive, to dissipate static, just like car tires and vacuum tubing under the hood. That might be really poor insulation for spark.

It seems to be working just fine.As I said,it's a temporary thing till I can get a replacement & it works in a pinch.I've got spark at the plug.

It sounds like somebody has been in there before and may have replaced the wire with carbon fiber wire. The carbon wire doesn’t carry spark as good so even though you can see good spark it may not have enough “umph” to fire under load.
I’d try replacing the wire with the proper solid core first thing, of course that’s assuming you can get the old one out.

I got the old one out without too much of a hassle.It was not copper core wire either,it was the same as the add on splice - silver in color.This is not a carbon based wire.I think the add on splice might've been a carbon fiber wire though. Good news - I got the saw to fire today! First I took a compression reading & got 120 psi,but that wasn't a good reading because the saw is only working with one pawl on the starter.I took another reading & got 135 psi.Once I get a new lead in the coil I think the saw will fire more consistently.The young man who I bought the saw from told me that he bought it at a yard sale 2 yrs.ago & had it stored under his father's workbench ever since then.I'll just bet this saw has been sitting idle for well over 30 yrs.

Here's a sad update.I finally got at this C9 today after picking up a NOS coil wire that was stiff as a board.I tried installing it while the coil was still on the saw & the wire wouldn't stay in place.I ended up pulling the coil off & know why it didn't stay in place.The "boss" where the wire is supposed to fit into had turned into mush.I very poor set up by the mfgr.of the coil.The coil is good in that it still produces spark,but not any good for retaining a coil wire.I have another coil from a C5 that I need to locate & see if that one is any good.Chances are it's the same as the one I'm dealing with now.

Ed I had a similar problem with a 17 and I just set it in place with epoxy gorilla glue and it works fine.

I thought about using an epoxy to glue it back in,nothing really to lose,but I don't believe I'll be using the NOS wire.I picked up about 3 ft.of solid copper core wire that's made for Stihl saws for about $5.It's much easier to penetrate with the spring than the NOS wire.I couldn't even penetrate the NOS wire using a pliers to push the spring in. If all else fails I've got an aftermarket coil here that I bought for my XP-1000 about 2 yrs.ago.It's supposed to fit the C series saws.I think Rowdy used this coil on his C91.

I ended up taking the coil off the armature & it's probably a good thing I did - it was like Play-Doh,complete mush.I had to take the coil off because no matter how I stuck the wire in the coil I got no continuity,there's no spade in the bottom of the coil for the wire to screw on to.I put the aftermarket coil on that I've had since March 2018,Lol Sometimes I buy things & have them laying around for a while before I ever use them.I also buy things because I get a good price on them even though I don't need them at present.Intuition maybe? If I have time today I'll finish assembling the ignition system.I hope I get it right.

I managed to get the ignition system put together today & I'm happy to say that the saw now has spark.I just need to shorten the coil wire & see what's causing the flywheel to bind (it acts like it's binding anyway).I did get it to fire on a prime.It doesn't help that the starter assembly only has one pawl on it.It's getting there!

Today was a bit of a challenge when it came to the pawl assembly.I had to take the pawl assembly off the C9 as it only had 1 pawl.I had a partial assembly here from a C5,so between the 2 of them I managed to get one good one.I had to take the keeper & spring off that holds the pawl on & put it on another assembly.That little keeper can be a real stinker to get back in place especially when a guy like me has gorilla hands.After about an hr.of cussing & fiddling around I finally got it. I put the recoil back on the saw & could only get an occasional pop & a seldom short time run.I figured it was time to pull the carb.In doing so I found the fuel line to be extremely stiff & ended up pulling the entire rear handle assembly to replace the line.I've found this to be the easiest way to replace the fuel line,7 bolts & screws & the entire handle assembly comes right off & it can be cleaned on the underside too.I always forget about reconnecting the switch wire.Lol The saw now has a new pawl assembly,a new ignition system,& will soon have a rebuilt carb.I had to buy a new fuel cap which cost $17,& that was at 2000 price.When cleaning the saw there wasn't much crud under the rear handle assembly & it has real good compression,so I don't think this saw ever saw much work.There's one thing that worries me a bit & that was that there were 2 reeds stuck open,but when I touched them they closed.There was no pitting or chips missing out of the reeds,they looked like new. I also found a couple of screws missing on the saw which were promptly replaced.It's coming together slowly.I've found that when I rush things that's when mistakes get made & I have to go back over things again.

Glad to hear you're getting there Ed! Of curiosity, did you have to file the aftermarket coil at all to clear the flywheel?

Post by edju1958 on Aug 14, 2020 9:59:27 GMT -5
I didn't file the coil,but I did notice it acted like it was binding.Where did you file it?I did have to drill out the white lead ground wire though,the screw that holds the condenser in place wouldn't fit through the doo-hickey.(sorry,my mind is blank right now as to what that's called,I know it's not a spade)

I just had one of those days when it doesn't pay to get out of bed in the a.m.First off I got up late on account of a tempermental alarm clock.OK,I'm an hr.behind now,maybe after I get my garden duty done I can rebuild that C9 carb,yeah right.I pulled the carb apart & put the new seat in only to find out that the seat prevented the metering lever screw from going in.Don't ever buy kits that are made in Brazil.I've bought kits from Brazil before & never had a problem.So I put the carb back together because God only knows when I'll get my next TILLOTSON kit.I went to do a return on the 2 RK88HL kits that I bought on eBay & had trouble with my printer.It only would print the packing slip & not the shipping label.I eventually lost the page that had the shipping label on & can't get it back no matter what I did.As far as contacting eBay like in the past,well I guess that's a thing of the past.All they do is give you useless links that have nothing to do with the problem I'm having.Maybe topmorrow I won't bother getting out of bed.End of rant.

And the kick in the head continues.I did manage to get through to "customer service" on eBay by using a chat window.The nice lady sent me an email with a link that was supposed to have the shipping label,but that didn't happen.She finally sent me another email with a photo of the shipping label & I was actually able to print it.Those useless RK88HL kits are on their way back to the seller. When I was looking for parts for aa muffler for my newer C9 I took the muffler off the other C9 to get an idea as to what parts I needed & found that it didn't have a baffle.I picked up a baffle when I was in Maryland,N.Y.last weekend & decided to put it in the saw today.That muffler fought me tooth & nail all the way.First the 2 tubes that are on the inside of the muffler were 2 different sizes,so I had to drill one of the holes out on the baffle a bit bigger to accept the larger tube.Then trying to get that dang muffler & air deflector back on was a feat in itself.It only took me about an hr.to put a baffle in the muffler & remount the muffler.Now it was time to start the saw & see how much it'd quieted down,yeah right.The saw will only run on a prime now.Time to pull that carb & rebuild itThen there were the other saws that I can't mention here.
