WD overheating?

[James Glendening]

After recently getting the new alternator installed and wired correctly in my friend's WD I took it for a test drive. I've driven it twice before but only briefly. This time I drove around the back yard in 4th gear at max throttle to check things out. I noticed that the left wheel when turning right knocks. Something I can fix by replacing the assy with parts from my junked WD but after I was finished running it I parked it and noticed that the fuel seeping out the air intake in the carb (the hose is not installed) was boiling. I've run 2 WD's and never ever seen fuel boil in the carburetor.
The temp gauge reads 170 degrees but it's a perfect, zero rust/wear, temp gauge. Im wondering if it's functional or just for show.

Could well be just a thing that was caused by not having the air tube hooked up and in turn cause it to pull in hot air instead of pulling in the air above the hood. Fuel now days boils at a lower temp then it did years ago since it has the alcohol in it and alcohol boils at a pretty low temp

The temp gauge is so simple not much can go wrong other then the needle stick so if its moving it should be just fine. How long did you idle the tractor before you shut it off? If not long I could see the carb easilly getting hot enough to boil the gas out

When I bought my wd it was doing the same thing under load. I flushed the coolant system with prestone super radiator flush and it took care of the problem. A lot of people say that just flushing with water will do they same thing, but I tried that first and it didn't do anything. As long as you get the correct amount of the flush and follow the directions it might take care of your problem. Good luck.
