hey guys, I got brave and deleted the base gasket. Used motoseal in place of the gasket and checked squish. End result was .020 at the tightest. the squish was .034 before modding. I let the motoseal sit for 30 mins before firing up the saw. Ran quite good for about 30 seconds and now its having idling problems. Wondering if I have an air leak somewhere? I played with the carb adjustments a bit but to no avail. the saw pulled hard in a log for a dozen seconds or so and then started having the idling issues. I'm confident I haven't burned it out from running too lean, the saw barely even got warmed up. Psi to begin with was 115 psi and motor is essentially new. inside was clean and flawless. Ran like a champ before the mod so I know it had good compression, I feel my compression tester doesn't give the full psi. after the mod it was showing a 7 to 10 psi gain. is that normal? saw went start now so I'm wondering what it might be. I will post a video I got right before the saw quit. it was running on full choke only and is showing symptoms of a possible air leak by getting picky about what carb settings it will start with. Choke, no choke, choke with throttle, then no throttle. Last symptom was the saw would fall on its face when I began to throttle up. played with the screws to richen or lean but no problem solved. should I re do the motoseal? what do you think?
