Problem figure out

are u saying that once its running,,,u have some raw fuel coming out of the exhaust,,explain your problem better

yes once the engine is running there is fuel in the exhuast. I can see fuel ontop of the water.

Are you sure its gas, and not oil?

check and see if your carb float isnt sticking,,,and letting gas dump down the intake,,,or swap carbs,,to see if your problem goes away:drink:

Make sure you don't have a miss. What size carbs are you running?
