Yeah,almost 2 yrs.ago I got a C5 that was supposed to be a "runner" from my local saw shop.It turned out to be seized tight.I ended up using it for parts for another C5 that I bought on Feebay.It didn't take much to get it to run,but it ran sporadically.After working on my C9 the last few days I kinda inspired myself,Lol.I pulled the C5 out & began going through it methodacaly. I gave it a prime & it fired,I tried another prime & got nothing.I needed to check for spark.I went to pull the plug wire off & ended up with the plug boot,spring,& a small length of insulation off the wire.I think it's time to replace the entiore plug wire.I still have a length of 5 mm. plug wire left from another C9 I worked on last summer.There may be more involved than just the plug wire,but that's a good place to start.I rebuilt the carb 2 yrs.ago & the saw ran for a short time so I know the carb is good.I thought the saw needed crank seals,but it may have the same problem as the C9 with a hair line crack in the fuel line.Only time will tell.

After taking yesterday off due to being under the weather I pulled the flywheel off & pulled the coil assembly as well.I figured as long as I was this far I'd clean the points & it's a good thing I did because they were tarnished pretty good.Getting the coil wire out wasn't so bad,it practically fell out.I put the new wire in by screwing it in like all the other coil wires I've replaced,but the old wire had a crimp on piece of electrical fitting with a piece of plastic on the end.I don't know if these wires on the C series were epoxied in or not.I tried saving the old electrical fitting,but it just fell apart due to age.Should I try to epoxy the new wire in?I don't know as the epoxy will adhere to anything & may possibly cause problems.

Sometimes I question sealant on the high tension wire end. Seems it is superfluous. The wire cable strands inside are very well connected with the screw, being wedged tightly. The sealant probably is there only to avoid water intrusion/oxidation corrosion between the screw and copper wire strands.

I don't know if Diox existed back when these saws were made,but aut a tiny dab of that will do what the sealant was used for.Of course I don't know how long it'd last either.The 5mm.wire I used didn't fit that tightly.I've tried using OEM plug wire,but it was too stiff to work with & not as long as I'd like either.

I worked on the C5 pretty much all day & got nowhere.I put new fuel lines in the tank & to the carb.Got it all buttoned up & I went to pull it over to check for spark & it was locked up.Funny thing though,I could turn it in reverse & it was fine.I figured it had to be something with the flywheel.I popped it back off & found the lever that holds the cover on the points box wasn't quite in the right place.I snapped it in & all was good,until I put it back together again only to find it didn't have spark.I think the condenser crapped out.I just happen to have a spare condenser on hand,so I'll try to get it on tomorrow,but the lawn needs to be cut desperately.

I had to replace almost all the electrical parts on this C5.The only thing I didn't replace was the coil,points,& switch.I had to replace the condenser,spark plug (wrong one in it),coil wire,& switch wire.I rebuilt the carb 2 yrs.ago,& just replaced the fuel lines.It had a thorough cleaning too.After all of this I'm happy to say that it popped on the 1st pull & was running on the 2nd pull.The carb is very touchy,I've got the lo set at about 3/4 turn out & it's still running rich.The hi is set at about 1 turn out.If I try to set the lo any leaner it wants to run at a very fast idle,almost too fast.Right now it's got a stack muffler on it,but not for long.I'm also trying to find a 3/8 sprocket for it only because I can find all kinds of 3/8 bars,& I think I can run a D096 bar on it.Homelite did make a 3/8 sprocket for the C72,I don't see why it wouldn't fit on the C5.

The phone actually cooperated today & sent pics! Here are some pics of the C5 without bar & chain.I seem to have a shortage of C series bars.

As I stated before,the saw is running quite rich with the needle settings set at - lo 3/4 turn out,& hi set at 1 turn out.The saw is blowing black smoke out the exhaust.I just remembered that I have another HL141B carb on hand.I'll take the kit out of the carb that's on the saw & put it in the other carb & see if it makes any difference.I had a guy tell me it was sucking bar oil.I told him if it was sucking bar oil it'd be bluish-white smoke,not black.
