So I have looked at hundreds of threads here and elsewhere. This one has me absolutely stumped...
I purchased from a guy that claimed that it was run only once in the past couple of years. I immediately thought that it would have some issues with starting. Well, I showed up, his dad said there was no way he could start it due to some back trouble. I choked it, pulled 3 times and it fired. Kicked it off of choke and it started and ran like a dream... No problems YET!
I got home and about 10 hours later attempted to start my new toy! Yipee, I finally got rid of my little toys and got a MANS saw
I did the same thing... Pulled and Pulled and Pulled and Pulled.. Get the idea? Took it off choke, pulled some more. Pulled the plug and it was firing BLUE. Thought there might be a problem with the carb due to age of saw sitting. Purchased a rebuild kit... Installed it, still nothing. Thought that maybe it bucked and sheared flywheel key. NOPE, just got my puller today and it was aligned correctly.
What now? Below is the specifics of what I have done so far.

- Compression 120 psi
- Vacuum and Pressure testing (Unknown at this time but liked thread with innertube from blsnelling)
- Spark is blue (Seems strong)
- New Plug BPMR7A and tried new Champion Comparable
- New Carb Rebuild kit. Carb was exceptionally clean, no crapola
- Adjusted metering to flush with carb body
- Adjusted carb L/H to 1/4 and 3/4 as indicated on body of air cleaner
- Checked Exhaust (CLEAN) - other than excess fuel draining when I opened it.
- Pulled flywheel - Key in tact and flywheel positioned corectly
- Depressed Decompression Valve and Pulled it back out, will not start either way
- Seems that when the decompression valve is in running position and choke is engaged, the saw pulls better (Sounds like rotation is clean). When decompression valve is depressed, does not seem to rotate as freely. Of course it sounds as if air leak is present then... What I am saying is that it seems a better chance to start when the decompression valve is not depressed and the choke is on???
- When looking through the decompression hole, the removed plug hole and the exhaust port, the cylinder and piston look very clean. No scars.
- No fuel anywhere on bottom of saw that would (TO ME) indicated a bottom end leak somewhere... Waiting to obtain vacuum pump...
- PLEASE HELP!
What the heck? It starts and runs. Now it needs adjustment but what in the world? Any ideas?
