I have a B & S Model 28B707 1153-E1 10 hp electric start with electronic ignition. It starts fine when cold, but will not start when hot. When trying to start it hot, it will occasionally pop. Any ideas as to what the problem might be? The carburetor is brand new. Spark plug is gapped to spec., but not new.
I would start by making sure the fuel solenoid on the carb clicks when you turn the key on and off, make sure you have spark at the spark plug. if those two things check out when the engine won't start, the I would let the engine cool then adjust the valves.
