Have the baby Falcon 110 Kazuma. Thing has been hard to start after sitting a while. Added clear fuel filter, and i could see that the fuel is draining out of the line. It has 2 shut offs, 1 at tank, 1 at carb. I always shut them both off, but line is still draining. Thinking of adding another in-line shut off right before carb. With fuel lines disconnected at carb, tank valve is working, and took valve off carb, hooked to fuel line to it, and it is shutting off as well. How is line draining? Seems as oil has a slight gas smell, so I assume it is draining through carb. Anyone else have/fix this?
Thanks.

 

the flote in the carb is stuck or there is a piece ov crap under the float needle.

of the chinese flaot needle rubber tip has hardend and rotted and does not seal anymore. you need to drop the bowl off of teh bottom of the carb and check the float/needle/needle seat. you can probably get a new chinese carb for like 20 bucks somewere on teh internet i bet.

 

Wondered about the float, but why doesn't the shut off at carb prevent line from emptying? Think will clean carb after son rides it this weekend. Thanks for reply.

 

if you take the fuel hose off of the carb and fuel flows out of it with the shut off valve closed. then the valve is bad period.

but even with a bad shut off the bike would run fine and would be no problem.

if fuel will not stop draining out of the tank when the engine is not running ,then something is messed up with the float needle.

 

Valve at carb is good as I took it off to check it, and good at tank also. No leaks that I can find anywhere. But somehow, fuel line empties as it sits with both valves closed. Can't tell for sure if oil has gas, but may, has slight smell. Some sort of vacuum forming? Gas back into tank or into carb? I have had to pull fuel line to get it to prime, as gas would not flow once line is empty and tank valve on. I have checked fuel cap/vent line and is working, and have had cap off and still will not flow. Little flustered, thanks for replies.
