My son's eton rascal 40 cc is leaking gas, I thinks it's coming from the side, not directly from carb. any ideas.

 

gas tank? shut off valve ? , gas line ? would be my first looks and inspections. "I thinks it's coming from the side, not directly from carb. any ideas." Does not give much to go on for specifics.

 

it's leaking where the air cleaner meets the carb

 

my guess without seeing would be a needle valve in the carb overflowing out the breather tube from the cleaner

 

how do you go about fixing that.

 

I'd take the air cleaner off right where is bolts to the carb. I just bought a used Hi-Bird and brought it home, the carb wasn't adjusted right and when I checked the air filter there was a puddle of gasoline in it. There could be multiple causes, but get the air cleaner off first and try to see whats going on.

 

I am not that knowledgeable on the newer carbs and injections as they are now. I am going on guessing and misguessing. I know carbs from 40 years ago which is a different animal but similar .

This to me sounds like a good start . Trial and error and deductions if you dont have a mechanic close to call.
