Main issue is to get it spotlessly clean inside and out, blow out all the passages in it, clean and free up the linkage parts, and know how to tune all the settings on it.

If you get another carb - you take a chance that it won't be tuned right anyway, and it may also not be quite the right one for your machine.

I recommend looking in at MyTractorForum.com - Tractor Forum & information, Discussion Board and Heavy Equipment Information

It is to tractors what FTE is to FORD TRUCKS...
