This is not for fun. I want to establish my chain elongation value. When I tried to time my ip using the bubble method, 24 degrees to the right of ot as viewed looking down from the front of the car was seriously out of whack. black smoke no power etc. I know it is not as accurate as we had discussed on a different thread, but it was repeatable several times. I have tried the drip tube method, and got no fuel at the attempt and do not know why.
