So after a long winter, its finally getting nice out so i went to start the 340 and it wont start. It was last started about 4 months ago and ran fine but was sitting outside all winter. It turns over fine, has spark at all the plugs and is getting gas in the carb and to all the plugs. The timing was not changed at all. I put a different coil on it thinking maybe it wasnt getting a strong enough spark, but still wont run. I tried starting fluid in the carb too. Wont even fire once. Any other ideas? Any help would be awesome.
