Re: MS 310 engine won't fire

Well, the saw is finally running. After going through every step suggested, it still stubbornly refused to fire. I decided to give it one last try before giving up on the thing. I pulled the carb and the 2 connecting lines and and  a vent line (I guess) back to the  tank.  Verified that the vacuum pulse line  and diaphragm pump in carb were working and the fuel line and filter were clear - could hear the air pulse activate the pump. I sprayed Sea Foam through the carb ports and blew air into the ports (although the carb is new) and cylinder chamber.  Then put it all back together and cranked it 4 times in full choke and high throttle and it fired - open choke and half throttle got it running. Apparently lots of oil residue in the chamber because of much white smoke from the exhaust. But, it settled down and ran well.  I'm using 91 octane ethanol free gas in every small engine that I have now in the hope that I'll have less of these problems in the future.  I appreciate the help that I received here in troubleshooting this problem.
