Either it has a vaccuum leak, or your carb needs cleaned/overauled. The latter is more likely!

I had the tractor running nice and smooth with the choke on and took a spray bottle with soap and water in it and sprayed every place I could think of and it made no difference in the running. So I guess I can deduct that it is needing a carb kit eh!!

As for a carb rebuild, some here say that it should only be a genuine CNH kit, not some aftermarket. You may find a seized/corroded accel pump piston.

BTDT before I tossed in the towel on the Holley. Not cheap to do. CNH does not stock replacement Holleys for 2000/3000/4000, only the Zeniths.

What were you hoping to see with soapy water?

Try spraying starting fluid(CAREFULLY!)around the throttle shaft, the carb to intake manifold interface, and the cylinder head to manifold interface. if you heaar the engine speed up, you"ve found your leak. look for vcracks or rust holes in the intake manifold also.
