fuel leak

  1. C

    Engine has no power after break in

    Hi I have a black 80cc engine that I got off eBay. It’s done a 1000km according to my speedometer at 750km I change the fuel mixture from 16:1 to 20:1 after I did that the engine started bogging I got rid of that by replacing the spark plug. But the engine still has a hard time accelerating...

    My petcock is useless

    Whether it is on or off, fuel goes through. I can run my bike in the off position. So because of this, fuel can freely go through when the engine is off and I can't do anything about it. Will this hurt my bike or is it fine?

    Carb Leaking

    I just filled my bike with gas for the first time. I was priming it and then after a few pumps, fuel started coming out from the primer and from under the air intake. Anybody know what is going on? This is my first project and I know how engines work but I'm no specialist. Thanks in advance. :)
