I have all the the TM's. (Thanx for having those available. My main issue is time. An hour here & an hour there to work on it doesn't work well. The unit was starting & running, but no juice. It wouldn't flash. Figured the speed swith was the issue, so replaced it. Didn't help, but I think I may have installed wrong or got a bad one - the rubber bushing on the drive shaft disentegrated - so as soon as I have time, I'll swap the circuit board to the old switch.
Meantime the engine cranks & will run for a minute then slow down & die - think there is a fuel issue with fuel pumps on the day tank. Haven't had time to test that yet...
