My 1970 Blazer is pig rich right off idle always sputtering and trying to stall on me. I need a rebuilt and someone to tune the complicated thing. Back in the day we would say 'tear that Quadra-bubblegum off and put on a Holly' but Hollys are gas hogs. I get decent gas mileage w these small primaries even with the worn out seats and needles, plus this old beast is all original soo.. I need a rebuild. Check this out kids, in the 70s gas station pumps had only two digits for the price per gallon because they never figured a gallon of gas would ever cost more than 99 cents!
