I bought a 4000 SU Gaser. It had some issues with the holley so I talked them into putting a zenith carb on it for me. They did put a rebuilt one from Wengers on it as well as new points and condenser. Ran awesome! Way more power than my worn out 3400.
So they said they had to remove/bypass the fuel pump because it would flood the engine using the zenith. I couldn't find reference to that in the forums but took their word.
I got it home and went to go straight to work with it. Drove it down to get my plow and let it run while hooking up. It stalled out after running a total of 10-15 minutes. Wouldn't restart. Eventually did holding choke full out and limped it back. After dinner I noticed the carb was spewing gas from the top. Drained it and rapped with a rubber mallet. Seemed to work. So next day again went to work with it with it assuming it was now fine and same - died after about 10-15 minutes and couldn't get it started at all this time. (Carb not flooding this time)
[b:2c3a8f9e6d] I'm assuming maybe ignition or coil but I question whether the fuel pump should have been bypassed?? And it's just running out of fuel?? When it runs it runs strong- when it got closer to 10 minutes it really struggled under load.

It's a 2-hour haul to take it back one way. Which I'm already waaaaay behind in my work without a running tractor.
Thanks for your thoughts and advice.
