Went to check my plugs last night,with everything apart on top of the engine,(very easy BTW),I put a balled up paper towell in each of the carbs to keep stuff from falling in,(they face almost straight up),well checked the plugs,(burning fine),little bit of dielec. grease,some antisieze compound,everything goes back together...do a once over,O.K. lets fire her up..nothing,she cranks but wont run,thought about it for a minute or two,well come to find the engine is not gonna run,not with paper towells stuffed in the mouths of the carburetors!!! :bonk:
