Just acquired this a few days ago. Have already cleaned it up some but man is it gunked up!

I will need the recoil starter for it- that is the only part that is missing so far as I can tell...IMG_20190824_151949.jpgIMG_20190824_152026.jpgIMG_20190824_152055.jpg

Sorry I don't have pictures of it in one piece. It has a (I guess) 25" bar.

Thanks for looking,
J.
 
Hey, that is mighty nice of you! I do have the two side case pieces as seen here, and the partly wrapped handle, but it's torn up a little.

If it helps, the 3 bolts on the recoil are 4" from each other. Thats's really all I need. I would gladly Give you a few bucks...IMG_20190824_214104.jpgIMG_20190824_214451.jpg
 
I'll check distance between the bolts when I have time tomorrow and let you know. If it looks good I'll throw the handle bar in too, it's in good shape and needs a home.
 
Just checked, should work. PM me an address and I'll stick it in the mail sometime this week.
 
I have one of these too. Currently a work in progress, I have to find a good used clutch for it or20190804_225848.jpg 20190813_220546.jpg pull this one apart and replace a broken pawl/spring/pin.

Neat saws, can't wait to hear it run.
 
Cleaned it up and- thanks VERY much to InfiniteJest, got a starter assembly on it, so here are updated pics.

I have not put much time into trying to start it. Unfortunately did not fire right up when I put gas in her... but I am getting good spark, and it pops with a little spray of starter fluid.
I will probably have to pull the carb off and rebuild or at least clean it.IMG_20190914_123657.jpgIMG_20190914_123710.jpgIMG_20190914_123725.jpgIMG_20190914_123657.jpgIMG_20190914_123749.jpg

Not that I'm saying to use starting fluid, it can wash oil off cylinders. But they do make starting fluid with oil mixed in. I use it in a pinch from time to time on stubborn snowmobiles. Never have I blown one up from it.
 
I have to figure out how to work the primer switch so as to have the best chance at firing it up... seems from what I have read this switch is not too effective sometimes and it's
better to squirt fuel strait into the carb?
