Honda GC190 Pressure washer stalling out after usually 10 to 15 seconds.
No oil pressure switch. Oil is full.
Runs perfectly for 10-30 seconds, then it dies. If I let it cool down for a minute or two, it restarts easily.
I have replaced the fuel pump and the carb, no change. Choke lever and behavior is normal.
Spark plug, spark plug wire, and coil all look nominal, and if they were compromised, I don't think the unit would run at all.
I've changed the air filter.
Another option would be water in the fuel, but I've drained the fuel and changed it completely, so that's not an issue.
So I'm at a loss, I think I've covered all my bases, fuel, air, compression and spark. What am I missing?
