Re: '70 K20 carb options

Well, since you don't know anything about the engine, the first thing you need to do is check your timing. Incorrect timing often disguises itself as carburetor problems. You'll want to set the intial timing at 12 to 14 degrees advanced. Do you know what type of distributor you have, original points or HEI?
