stupid motor

I think I have done everything to this engine and it still doesnt run right. This is a international 301 gas. I have adjusted the valves and the carb is adjusted right. It sounds good when it is running at one rpm. But when you snap the throttle it slobbers and sometimes dies. It did this before I installed electronic ignition. It did it afterwards as well. It is timed correctly and the spark is good. I think the advance in the distributor isnt working right. What do I need to do to rebuild the distributor so that it runs smoothly? Where can I get the parts? What do I need to watch out for so that I put it back together right? Also the tractor pops back out through the carb sometimes while I am starting it. Could this be part of the distributor not advancing correctly?

I think Id double check the carb, sounds like it could be a bit lean to me...

my 300 did that and the timing was off, also snapping the trottle, remember, you dont have a accelerator pump on these engines like cars do. (popping back sometimes indicates a lean mixture)

It isnt lean.

I was going to say a plugged passage somewhere in the carb. Still a good place to start. But when you mentioned it popping through the carb when starting, it reminded me of a small block Chevy I had with a worn out camshaft.

"It isnt lean." That may be the case, but some of the described running problems can certainly be caused by lean fuel mixtures.

ck the intake manifold for cracks or lose bolts ck the intake manifold between intake and ex it will run lean at times
