I have received one of those carbs where the fuel seat was not pressed in far enough. I think these are either untested, or failed units they sell. Cost more for them to take the return than to just ship another. I have the same running issue, ( not electrical) on two Kohler single cylinder engines SV590. Either surges badly or runs for short time on 1\2 choke. I have tried all new gaskets, governor adjustment, and valve lash. I'm really interested to see what you come up with here.

If that engine have a plastic cam gear, the plastic gear could have slip on the metal shaft and the engine run a bit out of timing. Just an idea!!
That's right, one test I did was remove the rubber stopper, didn't have a bolt short enough to replace the solenoid with. Right now I'm working on the ignition problem waiting for a new coil to get here. Not all that convinced it's the coil even tho it did not cold check properly. Because the spark seems to be time and voltage sensitive it would make more sense if its the replacement SAM module acting up.

Yes I found the seat problem as well and corrected it so the float was parallel, but before I could test with the adjusted carb the ignition died. I' ll get back on it when I get the coil next week.
After ignition fixed, may want to see if plunger rod partially blocks main jet with rubber stopper removed.That's right, one test I did was remove the rubber stopper, didn't have a bolt short enough to replace the solenoid with.

On the anti-fire solenoid, rather than just removing the rubber boot, cut the little shaft close to the body with side cutters. Once everything is running correctly, replace the solenoid if you wish. Not cheap.

Sounds like a plan, thx.On the anti-fire solenoid, rather than just removing the rubber boot, cut the little shaft close to the body with side cutters. Once everything is running correctly, replace the solenoid if you wish. Not cheap.
