Smell fuel when starts and stopped By thekidman96 (Read 541 times)

Hello people, i have a Boatian rebel 50cc moped/scooter, and when i start the engine it smells soooo much of fuel, and when i also stop, i do not know when riding as its probably behind me, (the smell), my scooter is 4 stroke too.

I have recently bought a new exhaust that doesn't fit to well and i had to make my own bracket for it, it is a straight threw exhaust, the weirdest thing is i thought it smelled rich but when i look at the spark plug its running lean... strange

I was wondering if the smell could be getting out of where the exhaust meets the engine on the down pipe, as I cannot see if it is gap free

Would appreciate all the help guys

Thanks

i'm no expert but i do believe that changing exhaust will sometimes, if not always, require you to adjust your fuel/air mix and or change the jets. That could be making it run too rich...but like you said it's running lean. Someone smarter will be along soon lol

Right after you start it check the carb area for any leaks, also check Drain Hose it could be leaking there. If you have to keep on cranking it to start it that will produce the smell of gas. If after you have been riding it for a bit and you smell gas it could be the ENRICHER not shutting off the extra fuel and will run really rich at low rpms.
