Having problem with pz19 on 4hp b&s. OK for two laps then quits and won't restart even with new plug. Plug black but not wet. Rich?
Help! Thanks in advance.

I don't know anything about that particular carburetor but the problem you describe sounds like a stuck float or needle and seat. It may be running a little rich but that's not what's causing it to quit. Carb bowl is not refilling and it's running out of gas.

Really? I ain't buying it, not to be contrary, but the symptoms are against that. The dry black plug after 2 laps does indeed indicate running rich, whether during a hard run, or more often by putt-putting around (running one of the so-called racing plugs) before the starting gun. It's the failure to restart that cries out against an empty float bowl. If it ran out of fuel during a hard run, then it should be ready to go again by the time you start trying to crank it again.
With the rich mixture situation, I would look to the carb for a lousy tuning setup first for sure. After that, there's so many things that could be wrong it ain't funny. It might be assumed that heating up could change things, but there's so many things, what could it be without more info?
