My engine has been completely rebuilt. New VW heads, 94MM cylinders, straight cam gear, all new bearings, new rods and pistons. I ran it for the first time on Monday, and was very depressed, after having done all that work and spent a gob of money, only to have an engine that was still sputtering and not idling well either. So, I told my sob story to a couple of very good engine gusy, one a local VW expert, and the other, Roy Szarafinski, of Corvair fame and the one who is building my Corvair engine with the Roy's Garage front bearing.
They both told me that if, when you throttle back, it backfires, then it is too lean, and if it stumbles, it is too rich. Well, as I said, it was stumbling all over the place. So today, I re-set the mixture and did some runs. The engine now has a very smooth acceleration, will idle fairly smooth at 800rpm, and has no stumbles when throttling back. It also has NO oil leaks. I still don't see any more than 3400 static, but I think that after it is run in, it will get a better idle and more top RPM. So, within two days, I have gone from down in the dumps, to on top of the world, metaphorically speaking. After I button up a couple of things and get the cowling on, I will take off and see if I can find the top of the world. Daniel R.
