Just did a search, and didn't find what I have seen before, I have the Rochester B 1bl carb, and it starts and runs good, but seems that it's running a little rich..Looked in my manual, and it was saying to turn in the adjustment, and back out 1 1/2 -2 1/2 turns..Really don't want to do that..My question..should I turn it in until it starts to stall, and back it off, or should I turn it until I get the best idle speed? Thanks
