I can get the engine to turnover, start and run for about 3 to 5 seconds with no problem. It runs real rough and sputters. Looks like it is sputtering gas or something out of carb when oil bath filter is off. Points are set correctly and when I pull on throttle I can see gas shooting out of the little needle in the carb. What is the likely cause of my problems? | | |

I'll try to answer your question anyway! These engines (216-261 or 228-302)are very sensitive to manifold or vacuum leaks. Check to see if you have a hose going from the manifold to the windsheild wipers, and if it is in good shape. Also check for any open vacuum ports amd plug em. I bet your engine will run much smoother.

If you know for sure you have spark and fuel, check timing. I'm assuming it has compression since it's trying to start. It may be low since the cylinders are getting washed from the fuel being pumped through it.
Good luck and keep us posted to what the problem was,

PS. can you keep it running with carb spray? If so, look at having a fuel delivery problem. | | |
