The motor has a rough idle but is great from about 1/8 throttle all the way up to WOT. Some times after I shut it off it won't start and if I pull the plugs they are soaked...I can put new plugs in and it will fire right back up...any ideas

It's just a single carb. I pulled it tonight and sure enough there was some jello in the jet...I noticed that the carb was a mikuni...were those original equipment on this motor?
