Hello again. I hope my posts are not becoming a bother. I am solo w/o anyone to coach me. 2 cycle is new to me. AC, no worries. You got me to take the next step which was to dump the bar oil and see what the heck was going on in there. Some basic use of eyeballs and brain yielded a positive result. You prodded me onward! Much appreciated. I get the concept of wanting it a little rich. Fuel acts as a cooling agent and a lean, hot piston is not good for a long life. I just wish I could get back to having it run for more than 5 seconds. Currently I am trying to figure out my next step. When I first got the saw I could get it started with some Gumout and (ether....which I now understand is a no no)....anyway, I got it to run with fresh gas and some placebo cleaner. Reved well, would hesitate when you jump the throttle but then rev great. Would start and run, but no power when put to wood. Backed off H and power issue was solved....then bar oil issue. Now, after sitting for 12 hours it will start on say 3rd pull, run, responsive to a few blips of throttle and then die and not restart after 5 to 10 seconds of running. Sounds like basic starvation caused by the fuel vent line being clogged. But, the fact that it ran until I shut it off just a day earlier, after tuning the carb, makes me think I have a different issue. The air vent is not going to clog up like that IMO but what do I know. Did I tune the carb in such a way that once started and warm it runs....but now, cold, it won't start due to improper adjustment? Coil...from my limited experience, if working once, likely still working as failure mode is zero function or 100% function. In short, it seems like a fuel issue to me, not electrical. What stumps me is that it was running continuously prior to the bar fix and my effort to "tune" the saw. Me thinks I have caused the problem. Or, am I still fooling with a saw that already proved to have a "stuck" bar oil check valve from non use and a saw that likely sat with stale fuel. All this may point to a carb rebuild. So, would AC say; "..PULL THE CARB and go through it with carb cleaner and replace......stop over thinking it...". Thoughts? Wisdom? Thanks!
