OK, well I thought that I had fixed it <img src="/forums/images/graemlins/frown.gif" alt="" />. It will at least run now and I can get it to idle but not well. It still wants less air and more gas. The mixture screw is at 21/2 turns like it should be. What do you guys think about this idea. I was looking at the manual for my mityvac handheld vacuum pump amd it said this:
Worn Valve guides
Worn valve guides admit air which upsets the air/fuel mixture. The vacuum gauge reading will be lower than normal and will fluctuate rapidly in a range of about 3" HG. As the speed of the engine is increased the needle will steady.

These symptoms are alot like what I've got. I can't get the mixture right no matter what I do, the reading is low and the needle flucuates or shakes instead of being steady.
How many of you out there vote for worn valve guides as the cause?
