Well..preliminary report is very good...I stuck it on and the truck ran very smoothly. I could not get the idle down past 700 but it was a very cold and wet day (ad it got colder). I put it on the day the truck had to go into winter storage (1.5 hours away in the Valley area) and I have not had a chance to look at anything else on the engine (timing, valve adjustment, etc...) That will have to wait until the spring. I've got a Langdon dist that I'm considering installing as well.
I'm comparing this to a badly set up Rochester B that looks like it has a warped cover. The first Rochester B I took off had a very bad casting - some of the internal mating surfaces were marred and the accelerator pump fit very loosely inside the bowl (and the piston was new). It was rebuild so I guess they just used the old worn casting. Too bad.
I set out with the truck to the storage garage and hit a major temperature drop along my trip...got caught in a fairly large flurry and temperature dropped well below freezing as I got high in the hills. The truck ran great - lots of power, good response, no lag, fuel economy was much better as well. The only problem I had was when I stopped to top up the tank, the only way I could get it started again was by holding the pedal to the floor. It also shut off as I turned off the highway.
My buddy thinks it was a product of driving along in a wet, freezing temperature at 60mph with no heat duct going to the carb. When I got off on the side roads, moving along at 30mph and out of the wind, the truck idled great (at 700+) and started right up again easily so he may be right.
Overall? 2 conditional thumbs up so far. Thanks to Jon (carbking) for the advice. But then again, I did not have the best of 1b's to test against.
