Well adjusting the injector pump seems to have solved my problems. She cranked MUCH better today and the surging at idle is gone! I need to lower the idle now but that's easy enough. I took some pictures today and she'll be for sale in the next day or so! :(

So I did some more research and came across a video on Youtube about the IP timing. I checked mine and it was about 1/8" off the mark. I advanced it and it seems to be running much better . . . no more surging. Won't know if I've cured the hard start issue till tomorrow.

I'll definitely try that . . . thanks!
