At my age I cant remember if I posted that my Webers are functioning great now. The forum's total advice indicated that patience and a little luck is required. I plugged all vacuum connections to start with. The brakes are being bolstered by strong but a noisy vacuum pump that gets drowned out by motor noise, and the distributor is set at a base 18 degrees with another 20 degrees of centrifugal advance for a total of 38. This appears to be fine for my needs. Power is awesome, and much better than the 650 Holly provided. Twenty five years ago I had a wilder cam installed to go along with roller rockers and higher compression pistons but unbelievably lost all the specs, so I was flying blind concerning jets and best emulsion tubes to use. I went through many combinations and must have gotten lucky. The car wants to idle best at 900 rpm, and idles reasonably lean. There is no lag when hitting it hard, and no problem smoking the 18/305 rear tires. Nothing looks as good as a set of 8 tubes rising up from the motor.
