I have been going back and forth on this saw for about a year. Its old, most likely wore out. But it was my dads and I want to keep it cutting (since he passed away its like keeping his memory in the woods with me)
Long and short of it, the compression was low (after cutting thousands of face cords of wood) and was in need of a rebuild.
It got a new piston/ring/cylinder and a new muffler (Old muffler was all rusted) I cant remember what parts i bought (its been almost 2 years since i started this "project") (I believe i got a "big bore" piston/cylinder kit and the open muffler, if i have to ill resort to factory components)
Has a new carb on it, but still have the original rebuilt and super clean carb (both carbs give me the same result)
i did a leak down test and I have no leakage. So im confident the lower end isnt an issue.
It has good compression (around 160psi) so I know thats not an issue.
Great big, fat blue spark. I know thats not an issue.
I set the air gap according to the manual and reset it and reset it so im sure its as close as close can be.
It feels like the timing is off. I can pull it 2-3 times and itll cough and sputter. I can even get it to run at a very very low idle for a few seconds (2-5) and then it dies.
I didnt see anything in the service manual about the timing. if thats even a thing. I do get some crazy pull back when im trying to start it.
I am about to take it to the shop (next week to be sure) but if its something stupid/easy im missing I'd rather do it myself. My dad gave it to me with the thought that I would be the one to make it run right again (im sort of good at this stuff) and I'd hate to be taking it in to have someone else fix it.
Thank you all for your help and assistance. It would mean the world to me to get her running right again.
