I've got a question. I got a grey Craftsman/Poulan 3800 off eBay last week. Had 140 psi, good spark and not much wear on the sprocket and chain. Put in new fuel lines/filter and vent line, cleaned and rebuilt the carb. I did have one funny thing happen when putting the carb back on - the gasket between the carb and cylinder didn't have a hole to match up with the carb impulse hole. The saw would fire, but not stay running when I got it, so I figured this might be why. I used a gasket punch and made a hole in the gasket for the impulse hole in the carb.
Got the saw running well. Was cutting with it the other day and after cutting up much of a good size maple I decided to take a break. I hadn't refueled yet so I topped off the mix and the bar oil which were pretty low. When I went to start it, not even a pop.
Pulled the plug and it was wet. Checked for fire and got spark. Pulled it over a few times to clear it out and re-installed the plug, still no pop. Tried a new plug, checked for fire - got spark again, but no pop with the new plug installed.
Switched to another saw and finished up the day. Tried to start the 3800 again after it had cooled for a half hour or so - still nothing.
Any ideas on why a saw that had just run well for maybe 45 minutes would suddenly not even give a pop, despite having fuel, spark and even a new plug?
I figured it might be a coil going bad, but it is still getting good enough spark to see it in bright sunshine.
