Farmall H carb problem

Harold Evans · Jul 1, 2009

My H will only run for about 30 seconds and then it shuts off like it"s out of fuel. I have cleaned out the gas tank and RedKoted it so I know there is no rust now (used to have lots of rust, however). I cleaned the carb and installed a new kit a couple years ago (before the rust problem, though). My question is: does this sound like there is some dirt or rust in the carb? I"m guessing the tractor is burning the amount of gas that"s in the bowl and then can"t get any more. Does that sound right?

One more clue: if I don"t turn off the petcock on the gas tank, the carb will leak gas at about a drop every three seconds or so. Does this sound like the same problem? I don"t know enough about how these carbs work, I guess.

Thanks for any advice you can offer.

I would check the screen at the inlet to carb. When you have it off, turn on gas at tank and you should have a nice full stream coming out of pipe. Also, take plug out of bottom of carb or open petcock if it has one to see if a constant flow will keep on coming with fuel line hooked up again of course. So far as the drip when shut down, your needle and seat are most likely the problem but would not be cause of engine not running unless crud is plugging inlet to seat and also keeping needle from sealing good. Lots of problems with getting them to seat properly. I always "coin or stake" the seat but you need something with same degree angle as the needle to do this. Few very light taps will shape the seat so it holds. I use an old pintle from an injection nozzle to do this. Not something everybody has laying around of course.

to add to what pete said, some of the other problems i ran into on my h carb, the float was a little crooked in the carb and would catch on the side of the bowl, also, check to see that the cross pin that holds the float in stays in the bracket. also, check the bowl gasket, i had one that was a little too wide and stuck into the bowl and would hang up on the float. for a simple carb, that lil rascal will make ya pull yer hair out!!!

Thanks for the helpful hints, guys. I will try these techniques this weekend, for sure.

Just in case I still have problems with this carb, is there a place I can send it to have it rebuilt properly? Aside from that, is there a place to purchase a rebuilt one or maybe even a new one? I'd really like to be able to drive my tractor. Right now, a half minute of driving isn't very satisfying at all.
