In this particular case it is doing its job. The main difficulty is timing from numerous tech articles that have been written dating back to type ones and old carburated fords etc at mountain elevations. I forget how much it is but I used to have it marked on the side of my distributor (when I had one of those) computer controlled timing adjusts for it. Unplugging the fuel pump will run the engine lean but then it will also be warm enough to start up when you put the fuel pump back into the system. There was a time when I would start up generators at altitude with a shot of ether only and then hook up the fuel lines. Amazing the difference a warm cylinder makes. jimt On 5/12/05 7:12 PM, "Karl Wolz" <wolzphoto@WORLDNET.ATT.NET> wrote: > A shot in the dark, but shouldn't the fuel pressure regulator tend to > compensate for altitude?
