About 5 years ago I posted a lot about repairing the warped body of a Rochester B or BC (or any of the other B series...they all are made using the same 4 screw scheme). It isn't a tech tip because that section is not being updated, but I designed this so that anyone can do this simply using only your gas grill and here it is:

To hark back to the original question, there is only 1 reason I would keep a Rochester instead of a Carter YF...and the reason would be that I could not find a Carter I could afford. For one important thing the Carter will not have the Rochester power circuit. This may have worked back when we had real gasoline. Since we got unleaded (and ethanol laced unleaded is MUCH WORSE) all bets are off. Now that gas will cause the power piston to stick fast in the bore and that will make the thing run horribly rich. Plus (and this is another given) virtually every Rochester B you find will have been run through some "rebuilder's operation" and that will have violated it completely. All springs, the power piston, etc will have been mixed up with many others. It matters less if this happens to a Carter as long as the model types are kept in the same group.
