I had that carb apart again today, re-cleaned and used compressed air on all passages. I sprayed carb cleaner thru all the passages including the idle and main circuits. Everything is open. I am leaning (no pun intended) toward a too lean mixture from a vacuum leak. Manifold is the only source I have not examined. New gaskets on carb halves and carb to manifold. I also resurfaced the carb halves by using a sheet of sandpaper on a sheet of glass. They are true. Gaskets seal good and I changed throttle shaft seal. I'm missing something here but I can't see it. I've had less trouble rebuilding Allison automatic transmissions :^(

Use propane torch (unlit) wd-40 or start fluid, and start tractor, and hose down the manifold to block areas.. see what you get.

Very ocasionally I get debri that the spray carb cleaner won't cut.. but the dip style cleaner cuts easilly.. though I'm sure you've cleaned it good... just mentioning it.. etc.

I soaked her overnight in a new tub of gunk. That stuff has not gotten any better smellin either, ya still have to wear it off, no amount of soap and water will rid you of the odor. Gnight folks, thanks for the ideas.

now I'm gonna throw my 2 cents worth in.I'm sorry I didn't see or here what your problem is but useing Gunk carberator cleaner won't help you.I've used it and you could leave a carb in there for a week and still have dirt.Go to NAPA and tell them you want some of the good stuff,Its not cheap but it'll clean her.oh and if shes still not fixed restate the problem and let everyone hash it over again I have faith these guys will figure it out.

I use the chemdip myself. Takes paint of instantly, disolves rubber in seconds.. starts eating plastics on contact... turns skin white in about 5 minutes.. and leaves a smell kinda like kerosene for hours to days afterwards..
