Just assembled an engine and am in the break in process. During one of the runs, the motor coughed, spit and died. My first thought was timing (34*) or ignition, so I checked the flywheel key and coil gap (0.045). They both seem to be good. Rechecked the valve lash and its at 0.002 to 0.003. The spark plug is dark but not fouled. When I try to restart, it backfires through the pipe sometimes. Is it possible that some trash has got in the carb? Maybe something in the new fuel pump gotten into the carb? any other possibilities?
Thanks in advance
