The HMB 46W carbs on my 74Z are leaking alot of oil into the intake manifold and generally making my engine run bad. My question is is there anything I can do to fix the problem or should I replace/rebuild the carbs. Also 20 weight oil is hard to find around here any ideas on a substitute? Any hel[p would be greatly appreciated.
