Any carb trouble you have should be easily fixed by purchasing some new step-up springs from Edelbrock for you Q-jet. Edelbrock #1994. Check your vacuum at idle..in gear. You need the spring that is rated about 2" below your guage reading. I think your engine is way too rich when you load it down with the stock converter and is just signing off when you drop it in gear. After the correct spring is installed you should be able to dial in the idle mixture screws for a fairly clean idle. Please do not drill on your Q-Jet without really understanding why you would be. Holes are hard to make smaller. The idle restriction can't even be reached by a standard set of bits, its too far in the well on purpose. Bits are sold in sets of 10 and about $3.00 each. Beware!!! More to come.....
