I have been noticing that I smell gas lately when I drive my 250ex....I did not notice this before.....is it the cold weather...also my spark plug got fouled out a while back for no real reason...is there a problem in my carb? I don't seem to have a leak however..nothing on the ground and my garage does not smell like gas.

 

Just talked to a guy a work...he said that he smells gas all the time on his snowmobiles in the winter, the gas does not disapate like in the summer...same principle as a cars exhaust or your breath being visable in the cold...does this sound about right?
