Old MF Tractor Questions

   / Old MF Tractor Questions #11  
My 1955 Ferguson TO-35 uses the Carter UT carburetor . All of the aftermarket fuel system parts I've found are now made in China, and they range from poor to useless in quality. I bought a replacement fuel shutoff with glass sediment bowl assembly from Tractor Supply. It's a Chinese job. No fuel would flow through it when I first bought it, and I had to do some drilling to solve that problem. Also, the shutoff valve leaks, so overall the unit is worthless. Also, I've had a heck of a time stopping the carburetor float bowl from flooding since changing to the Chinese needle and seat. I've had three of them in , and after a few days they all start to leak and flood the carburetor. That problem is driving me nuts, and I have to use a shutoff valve I installed at the carburetor to make sure the fuel is shut off unless the engine is running. I have an aftermarket fuel filter in line, and I've had the carburetor off at least half a dozen times to look for the usual problems such as a blocked vent, a sticking or misadjusted or leaking float, a bad gasket at the seat base, etc. Everything looks ok every time, with no evidence of dirt getting in.
Prior to this, the oddest carburetor flooding problem I ever encountered was with my riding mower. There was a tiny float chamber air vent that got clogged by a mud wasp, and the mud survived my carburetor cleaning. That took a few tries to find !
