Done a pretty long test run on johnson 85 esl73m,about 30min,seems to be working ok. control unit did piip one time but after that i have heard nothing so i kept testing for 20 min without ant piip and it runs well i must say. The area around the two holes on upper-stem,right belov the lower engine cover got pretty hot,its normal maybe? i mean it was used on wot many times during this test,i can see a tiny bit of smoke coming out those two circle holes on upper stem also.
