Engine wont start

Hi, I just finished building my motor bike, and I only got it to start once. Now, i everytime i try to start it, it starts for a few seconds, then dies, then a lot of fuel just leaks out of the carb and exhaust. What should I do?

Are you forgetting to turn the choke off? If not, it could be as simple as a stuck float in the carb.

Did you do the stuff I told you about on the chat?
Is it still giving you problems?

Sounds like it could be that the float level is set to high.Adjust the tangs down a little till the problem resolves it self. Don't forget to clean your plug!

How do I fix a stuck float in the carb??

bend the brass tabs so that the float does not rise as high it looks like a brass y it holds the float

Welcome to the forum, glad you joined us.

Bend the tab circled in red to adjust the float level, Down for less fuel, up for more fuel. Make very small adjustments. You may have to do it several times before you get it right.

Any luck yet? Have also come across pin holes in the float...that will weigh down the float allowing to much fuel to flow in. The floats are made of a very thin plastic and are virtually impossible to fix as they seem to always have the leak on the inside seam were the float floats up and down were the needle and seat are and the tolerances are to close to put any sort of patching compound as it restricts the movement of the float causing the problem to compound itself even worse...remedy-get a new float and replace. You will be able to tell if this is the problem by taking the float out and visually look to see if there is fuel inside the float itself.Hope this might shine some more light on the problem that you are having.
