rebuilt Q-jet model number 7043240. i have over 250.00 in this carb but because there is a repair fitting on the fuel inlet i will sell for 100.00 the carb does not leak and is ready to bolt on and use. the threads on the inlet were questionable but i didnt notice this until after the rebuild and opted for the fitting you see on the carb that uses O rings to seal. I tested this carb on my 70 GS and it does not leak
