I recently removed and cleaned my carbs. Now that it's back together, it only runs for a short while before dying due 2 of the carbs flooding (the two on the fuel pump side). I reopened up the carbs and checked the floats they didn't seem stuck open. Spark plugs fouled up? Spark plug wires? When it runs initially, it sounds OK so I don't think its the plugs, but I'll pull them out to check. What else could it be?

Thanks!

Are the float heights set properly? That can be a cause for carb flooding.

 

I had the same problem and it ended up being my fuel inlet floats. They kept getting stuck open causing the carbs to overflow.
