Boiling Fuel

Thanks,

Alex

When I first got my TE-20 I had the same thing happen to me. I parked the tractor and the fuel was in a full rolling boil. I when I opened the cap some came out and rolled off the tank and onto the manifold and instantly vaporized. Good thing I don't smoke and there was a light wind that day. (No Fire, but I was very nervous for a time)

What I found... I was low on fuel so the smaller amount was more prone to boil (though even a small amount should not boil.

2) The Radiator passages were plugged with years of chaff and grass debris from cutting. Fix: I blew all the debris out using a compressed air tank and blow nozzle. The passages are clear and I have not had a repeat of the problem.

A quick check of the gas/air mixture to see if it is running too hot is to run the tractor at night and see how bright the manifold glows. A dull red is normal getting more cherry red may indicate a need to modify your fuel mixture.

Might want to check your engine timing, your carb mixture, clean your radiator fins and flush your radiator, maybe check your thermostat. Those are the usual culprits causing overheating.
