Longjia 125cc raptor had problems with fuel leaking from the bottom of the carb and though the air filter. Just put a new carb on OK for a few day now doing the same any clues please


New carbs aren't known for leaking unless you had it open and altered some thing. A float can get stuck if you let it sit without using it. Should put stable in your tank and run it so thestable gets into the carbs.
Check above the carb for a gas leak from the gas hoses and check the gas tank. They may be running down onto the carb and just appears like the carbs leaking

Fuel leak cx500


there are orings, you need to unbolt the carbs apart. you might have to synch the carbs afterwards. you might as well try and get a rebuild kit and clean all the jets and replace all the rubber parts in the carbs.

I have a 09 455 rancher that will start with choke on . Idles with choke off but bogs when throttled up. I believe the bottom carb gasket is leaking. Parts houses say call for carb parts.


If gas is leaking from the carb, can you see if it is a damaged fuel line with a leak or coming from the carb itself. If it is the carb tighten the screws on the carb itself. If neither one is the problem you probably do need a carb kit installed. Hope this is helpful. Best regards and good luck.

Sumthing is wrong with the carburator


hi,
to get a good combustion inside the engine, you(engine) needs fuel-air mixture, since it leaks fuel the mixture is too rich on air. Where does the carb leak? maybe it's just the connection that leaks...I mean where the fuel line connects to the carb, If it leaks there it also sucks in extra air instead of fuel, and therefor the engine doesnt run smooth, choke or no choke, that makes no difference. Check that and if it leaks there just change out the fuel line with a new hose.
It could also be the little rubber ring that seals of the carb, If it leaks from the top of the carb...it's the little ring. Take off the top of the carb and check the condition of the ring, if faulty.. replace it with a new one.
Hope this helps....can be pretty dangerous riding around with a leaking carb... Good luck, Gilbert.
