Duh.... ok it looked like a machined alum step. .012" alum and
.008" Brass shim so .020".
The switch action that I was taking about was a High rpm idle that I couldn't decrease with the idle adj or end point on my radio.
and yes it was followed by soaring temp.Low end mixture too lean? Sounds right now that I'm on the keyboard. I was trying to Richen the High end because the rpm's were so high then it would die on accelleration (bogged down) Too Rich....
I think I got it now Just hadda Read it and look at it a few times to see.
So here is my mistake I think...... I leaned the low speed too much causing it to Rev High then trying to compensate and mistaking the high rpm for idle adj or too lean High end I had a mental breakdown and screwed up what I should have left alone and left alone what I should have screwed up. Therefore Screwing up everything that I have been learning......
Thankfully I was able to run one more tank through it after I turned the right screws the right way and my motor will live. I tore it down after bringing it home and everything looks ok.no scoring, pits or discoloration.
