Kohler SV720S Twin Courage 23hp.
Both modules are firing. Unplug #2 plug (drivers side) and it fires up and runs on the #1 actually pretty smooth.
Plug in #2 and unplug #1 and engine just turns over, but no crank.
#2 plug is dry.
But the carb is a single barrel carb. Just inside the intake, it's wet on both sides.
Both plugs are good. (Not new)
I've adjusted the valves earlier and replaced fuel filter.
Compression test on #2 cylinder was over 200lbs. While #1 was about 150.
Thermal temp test was 350 plus on #1. About 150 on #2.
How is this even possible that if both mudules are firing, and it's a single barrel carb, could the #2 cylinder not be getting air and fuel?
