This carb was stock on many early model 998cc engines and came factory on some of the 1275cc engines with the proper needle..This will fit the 2 bolt diaginal or 4 bolt intake manifold. Ideal if economy and performance is your objective! Uses the pre 1980 red jet tube and comes with all new seals, gaskets, needle & seat, jet tube assembly, and new throttle bushings if needed. All parts are inspected,cleaned,and polished. The air filter to carb elbow will not be inncluded unless you specify in the comment field you would like one.
