It's here.....it's bad ass and it's old....and freaken heavy. FINALLY after a good 6 months of searching this big tub made it to my front door. Paid to much in my opinion, but I was at the point of despair in finding one....especially when a super sweet 9-23 direct just went for $250 on ebay and I missed out. ANYHOW....she has no spark and is low on compression. Piston has some minor scoring but not enough to make me think lower cylinder wall plating is peeled. Rings are free. As far as spark....points are clean and stop switch disconnected and still nothing. Hoping a bad condenser which leads me to ask.....does anyone know if the nova II chip can be used on these coils? I know they are used on the out board coils so not sure if inboard makes a difference. Want to hear this thing run and maybe make some cuts with it before I strip it down for a resto/rebuild. 004 by TJ McCauley, on Flickr 003 by TJ McCauley, on Flickr

Nice, Nice!!! Now you're making me jealous. Looks in great shape too. I see the wire from a customer tag on the handlebar. Came from a saw shop?

No major pitting anywhere that I can see so I did get lucky as far as external shape. Came from a member off of another forum who also sells on ebay. The guy to Really be jealous of is one on facebook and he has like 5 of these gear drives and 3 of the direct versions. Made ME really jealous. lol

Great find, I can't imagine hauling one of those saws around all day long in the woods to make a living. The guy that did just that, is the one I want on my side in a barroom brawl! Hope you don't have too many issues with the saw, keep the rest of us in the loop. Sure dwarfs that 10-10 behind it

Nice find, very nice. You (we) will have a lot of fun with that one. (Thanks for buying it for us!) Get with Joyce! (NOS condensers can be bad from sitting so long, don't be too hard on her.) My thoughts are that a chip would work but having had an SXL with a chip that was a bear to start, if you put one in, hang on with everything you have when you pull that rip cord. :{) A big motor like that might be very tough to start with the ignition advanced. I have a project in mind that would match up brand new manufactured automotive condensers with uses in these old saws, I have not got to it yet. AND, what car uses condensers anymore?

I've used a few automotive condensers on oddball saws that there were no parts available for.

Hi TJ,Pls stay away from the Nova chip,they're nothing but bad newslI found an old thread here on HOH that was about 3 or 4 yrs.ago,it was in "Ignition" category.There was a member who went through 3 of the Nova chips on an SXL-923(?).& still couldn't resolve the problem.Read this thread & I'm sure you'll have w2nd thoughts about the Nova chip. houseofhomelite.proboards.com/thread/3545/keep-loosing-nova-ignition-module

Sawnami, can you add part numbers or general ideas on using the "wrong" condensers. I know that if the capacitance is wrong it can lead to shortened life of the points but I don't know how available condensers relate to the correct ones for a saws or how fast point failure would result. What have you used successfully in the past? I like your pile of parts. :{)

Another thing to think about here is,rather than using an automotive condenser,how about using a condenser from another brand of chainsaw?I'm sure that Homelite,or McCulloch,or Poulan,etc.didn't have their very own patented condenser that was made specifically for Homelite,etc.,etc.When a mfgr.makes a condenser for one company,they also make it to fit other brands as well.This makes it much more cost effective to produce at a cheaper rate per piece,& that in turn makes a larger profit margin.

That is a great thought, usually the major difference is the bracket or the wire lead.
Lawnmowers, tractors, tillers, all of them could be candidates.
The electrical size of the coil is what determines the size of the condenser, they need to be matched to enhance the spark and protect the points from pitting and wear.
Most of the time people seem to talk about .15 to .19 mfd for a size in saws, I don't know if that is universal. Anyone know? How about other ignitions, anyone know anything about the mfd on those?
I used to have a link to a great ignition page with all kinds of info and experiments that a guy had done. It got lost in a computer crash a while back.

Most if not all capacitors I have dealt with are .19 to .22 uF 400-600 volts. I have used modern manufacture stihl caps due to their small size. I once bought a few NOS caps knowing the risk and lucked out....one WAS good. I can check them with my tester which can go up to 1000v if necessary.

Wow that read up was interesting. I've installed nova II chips on 009 stihls and an 056 av without any issues. We had one sitting around at the shop so I figured I'd grab it for the hell of it and see what happens. If it blows I've lost no money to worry about and we can add that the 50's and early 60's coils are out of the line as well. Wonder if stihl coils were different.

The old beast ran tonight! One thing I've found that has worked a second time is charging an old condenser with a volt meter. This saw legitimately had no spark after a good points cleaning and verifying no bare wires and even disconnecting the stop switch. I had tried this method once on my 770GS rebuild to see if the condenser was good. Basically you take the meter and put the knob in the OHMs position and touch the ground lead to the condenser and the positive lead to the wire....allow the numbers to go up a ways and then turn to voltage and see if it has a charge. Mine had a good charge and took quite awhile to drain. Reinstalled the condenser and I have spark....good spark...enough so that with some priming and fuel in the tank she runs! Not great by any means, but it was sweet to see the old boat smoke like mad again. haha She needs rings REALLY bad though. Compression is way low. I'll try to get a video up soon of it running a bit.

It's always good news to hear that another old Homelite has been revived & can come off life support.Good to hear you don't need to pull the plug on it.Lol
