My engine lunges when starting out in first gear. It does not make any difference cold or warm. It runs great going down the road, but when starting out it really jerks, or if I slow down then shift into second and start out it lunges also. My neck can't take it anymore! Could this be a carb problem? The carburetor has been rebuilt, but the base shaft has a lot of play and tends to leak. I have checked the normal things such as points, plugs, timing , etc. Also, this engine only takes 4 quarts of oil. It does not have a filter. Is this normal?
