I got a briggs thats being stubborn! Brand new carb usually starts up 3 or 4 pull. Runs about 2 minutes then dies. Won't start for at least an hour later. Runs smooth for the 2 or so minutes. Was thinking either intake valve hanging up or coil? I have good spark even after it dies and its got good compression. I had the head off no build up
Any ideas?

Runs then dies is typically a fuel line blockage.

I suspect that the inlet needle is sticking.

If it starts to hunt really bad and pop, burp and fart and catch itself with a puff of black smoke out the muffler at 3600 rpm even though the carb checks out for fuel flow, jets open, float adjusted right, carb vent hole is open, fuel cap is not clogged and gaskets are sealing correctly then it is the coil breaking down when hot.

 

Switch out the plug to a re-gapped good known plug and run until hot, if it dies then pull the plug and crank over, if the spark is red/yellow then 9 time out of 10, it is the coil, if pretty blue/white, it is the carb.
