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. :)

When you push the button it holds the float down so it can't shut the fuel off by raising the float needle. If it stops leaking with the button released your ok. If not and it just keeps leaking you need to service the carb.

It's not a primer it's a float tickle, and a badly designed one at that, however has something in common with a primer, using it too much floods the carb.

That button doesn't seem to help much and even falls out of carbs too, the last one that did that I plugged the hole with a quarter 20 bolt since it never gets used anyway.
