Re: 78 K20 Gas Milage Suggestions

Thanks, I do have a vacuum gauge and timing light. I dialed it in after I rebuilt the carb. I'm going to advance the timing and re-tune this weekend (as well as try a few other suggestions people gave). Its seems like most people are thinking that is where I am most likely to gain economy. Please feel free to add other suggestions, but Ill let you all know how it goes.
