IH 424

Two Banger · Jun 21, 2010

The tractor will run fine and start fine until it gets hot. When it gets hot it would drain the fuel filter and would die because it was not getting enough gas. We checked the fuel pump and its working and the fuel lines are open. Any suggestions on how I can keep gas comeing to the carb?

Have you removed the fuel shutoff / sight glass from the fuel tank and checked it out? Every time this has occurred on one of my machines it is debris in the tank blocking the shut-off. Last time was actually on my 424... remains of a dead fly... Couldn't see it until I removed the shut-off and took a look.

if the tank is vented (and not creating a vacuum as fuel is removed by engine) there is absolutely no reason fuel flow should be restricted. Unless there is a blockage...

First off, put a spark tester on one of the plug wires and watch it as the tractor begins to warm up to verify for SURE that you are not actually losing spark.

If the spark continues strong as the the engine begins to act up you KNOW it's a fuel problem.

"We checked the fuel pump and its working and the fuel lines are open."

If you are indeed having fuel problems, that statement probably isn't 100% true.

First off, do you have the proper vented IH safety gas cap?

First thing I'd do is (SAFELY, with the tractor COLD, outside, fire extinguisher at hand), take off the gas cap, then blow backwards into the fuel line from the sed bowl with compressed air.

(If you're too aggressive with the air, gas MAY spatter out the filler neck.)

This will clear out any crap that may be in the fuel lines or the fitting/valve at the bottom of the tank.

take a compressor and blow backwards into the tank...
