Need some advise here. The 3020 has a Zenith OE-2219A on it and it suddenly caused the engine to run really rough (Good fuel flow, sediment screen in place and clean). I took the car to a guy who cleaned it up....and there was alot of accumulated crud in there...cleaned the orifaces, floats good. The fuel shut off solenoid is bad and had been bypassed and no amount of adjustment would make it work. The vacuum pump is worn. Is there a way to bypass the solenoid needle so that it can be functional? But that doesn't deal with the other pump issue.
I have a MS USX 36 that came with the tractor and it has a bad diaphragm and some other parts.
Here is the dilemma?
*Try to find parts for the Zenith solenoid and pump (?$$)
*Get a kit to repair the parts for the MS USX36 and try that ($60)
*Buy a new/rebuilt carb ($300-$600)
