Runs Flawless for 10 minutes then acts like the plug fouled and/or detonation.
I have cleaned the carb 4 times. run with and without the pump. turned the air screw from 1 to 1 1/4 to 1 1/2 to 1 3/4 to 2 and 2 1/2 with the same result.
I have no tools for compression or leak down. I know I can rent compression.
