Cliff, earlier this year you reworked a qJet 7040256 (1970 Olds W30 4-speed car) for me. Someone had gotten inside the carb and really buggered it up, like installing a power-piston when that part is not used in a 7040256. Anyway, things happened and I just now installed the rebuilt carb you did for me on the car, and the engine fired right off, and ran beautifully! I am forever grateful to your for seeing that the job is done right. Thank you. Stephen
