Throttling going uphill - then it dies.

dactura · Oct 15, 2018

This problem first occured when I was pulling a scraper full of dirt uphill. Throttled as if it was getting fuel, then it wasn't, then it was; doing the herky jerky until it died. When I started again, raised the blade and continued on, it was okay... until it started doing it again when it was not under a load.

I guessed it might be a heating problem because it died and would not start until it sat for a while. I changed the thermostat. That was not the problem.

Now I think it might be the governor - but I'm not sure. I don't want to start taking stuff apart until I'm sure.

My battery is getting ready to crap out. Would a weak battery cause the tractor problems like that?

Any ideas on this?

Check the fuel flow from the bottom of the carb bowl remove the plug and catch the gas in a pint jar.It should fill the jar in about 2 minutes. If it dosen't check the screens all 3 of them.If screens and flow is ok,then check the carburetor float level it may be to low.

Thank you Den. Failed the pint in 2 minutes easily. Carb screen was clean, but fuel bowl contained sediment and lots of silt came out of the tank when I removed the fuel shutoff.

I had a problem with the standpipe becoming plugged, ended up having to replace the complete unit.

Yes, that may be my problem. After cleaning the screens that were not dirty, fuel dripped back into the bowl and then stopped dripping. If I were ambitious, I'd blow out my assembly and try and make it work, but I think I'll just go buy another one and investigate why the old one isn't working.

I also might see about converting the crappy one into a device that will conveniently empty my gas tank: attach a hose to it.

I think Bruce's rule 10: "• Carry (or mount) a fire extinguisher and make sure you shake or tap the powder loose about every two months. A fire extinguisher can be easily mounted with radiator clamps or secured with velcro to the left side lift arm (the one without the leveling box)." was made for people such as I.

This could also mean your sediment bulb gasket and float valve are sealing properly.

Scenario - Gravity fed fuel delivery system. Float bowl full of fuel. Float valve closed. The positive pressure in the sediment bulb (air lock) stops the bulb from filling. Start the tractor or remove the drain plug from the float bowl, the air lock is obviated and you get fuel flow.

"fuel bowl contained sediment and lots of silt came out of the tank when I removed the fuel shutoff."

How far are you opening the fuel valve when using the tractor?
Two full turns is normal operation, all the way open is the "reserve".
That reserve picks up far more contamination from the tank.

Problem solved: I replaced the fuel bowl assembly.

The well inside the screen filled up with sediment. Blowing it all out with an air hose from the opposite side inlet hole cleaned it all out quickly. The old screen was sitting inside the well, but the new assembly has some kind of glue on it that holds the screen tightly to the inlet so that all that stuff on the bottom cannot easily get in.

The old bowl assembly, the gasoline dripped in like an IV, but the new assembly, the gas came in at a steady slow stream - so next time this happens, that will be my test.

Any idea what kind of glue they used to glue the screen to the assembly? I'd like to fix my backup fuel bowl assembly so that the screen is attached to the assembly.[/img]

Glad you got it fixed. See that little stand pipe inside the screen?
With the valve open two turns, fuel is fed through that pipe only.
The screen doesn't really come into play.
When you open it all the way, there is a second hole, down in the
bottom, inside the screen, that fuel is allowed to flow through.
Obviously, if the screen is full of crud, fuel doesn't flow well.
But it may get you home if the gas is lower than the stand pipe.

Dactura, I recall checking to see what that glue was, and came to the conclusion that it was epoxy.

Thanks Showcrop! I'll mix some up and fix my spare assembly.

Royse - I read about the "two turns" system but never used it. After all the trouble of replacing the fuel bowl assembly it makes more sense to use the "two turn". I had been peeking into the tank now and again; running out of gas randomly.

Getting the tractor back to working order gives such satisfaction as one might get from a two week trip to Europe and I didn't even have to get on an airplane! Thanks amigos!

dactura,

let us know of the epoxy works
