Go to the 11:00 min mark in vid. (thanks for the link) you'll see what I mean about the air door opening affecting mixture. We are talking about a ping not a bog right? If you stay on the floor I'm assuming it keeps pinging right.
The right small screw driver will keep the tension spring from unwinding.
Yes its definately a ping and no bog whatsoever, and yes, it keeps pinging until i back out just a hair, but a hair is all it takes. I adjusted the air door years ago to fix the bog and it does great besides the ping..
