Thanks for the suggestions. Went through the carbs last spring but have it on my list to check them out again. When I first got the bike it had some trash in the fuel line that stuck a float open so at that time I cleaned everything that touched the fuel but time has passed. I have an old one eyed cat that hangs around and probably brings me an average of 20 mice or rats a month and has done so for 5 years so i can probably discount that problem. He has to hunt in a field a couple of blocks away since he cleaned out the neighboring lots/land.
