Engine dies

Sun May 27, 2007 2:41 pm

Hi All,

I just got my Farmall Super C painted, and I put a kit in the Carb (Carter Carb). I don't have any specs on what to set the float at, and when I first put the carb back on and tried to start the tractor, it was getting too much fuel, and fuel ran back into the air cleaner. I continued to work to adjust the float until I thought it was close to being right. When I fired up the tractor, and ran it up a hill on my place, it ran good for a few hundred feet, then it started cutting out like the fuel supply was going away. It dies after it cuts out a few times but will start back up. When I turn it around and head back down the hill toward the shop, it seems to run fine or like it is continuing to get the fuel it needs. I don't know if the float still isn't right or what. Any ideas?

I would start by checking the inside of your fuel tank for dirt and obstructions to the fuel outlet. Then I'd move down to the fuel strainer. Make sure the bowl and screen are clean. Do you, by chance, have an inline filter installed in the fuel line? Don't know anything about the Carter carb, so can't help much there.

I took to tank off and cleaned it out with mauratic acid, and put in a new in-line see through fuel filter. I can see the fuel in the filter when the tractor is running. I just thought maybe the float isn't adjusted right yet, and it is burning the fuel out of the bowl, and is dying. Then when it gets fuel back into the bowl it will run again. I could be totally wrong.

How about the fuel strainer? Was it cleaned good, also? Try temporarily replacing the inline filter with a short section of steel or copper tubing. If the Super C is like the Cub, the fuel system is gravity flow. Not all inline filters will work on this type of non-pressurized system.

Fuel level inside the tank. Add a couple more gallon of gasoline.

Hi guys,

I put on a new fuel strainer also. Speaking of the gas, I thought about that too. I only put about a gallon in when I got the tractor ready to run. I wondered if the fuel was running back when going up hill. I will put in more fuel and try that. I know it's a simple thing, but that could very well be it. I hope!!

Thank you all for your replies!!

Well, the saga continues as they say!! I now have about 6 or 7 gal. of gas in the tank, so it should have enough fuel. It still is wanting to cut out going up hill, and acts like it wants to die but this time it don't completely die. The last time I do believe it was too low on fuel. I am wondering if the float adjustment is wrong, and maybe hanging too low, not allowing enough fuel into the bowl.

Any thoughts?

I would still try bypassing your inline fuel filter before I pulled the carb and played with the float.

I agree with Don. If you are using a Fram G1 or G2, or something like it, they often times will not flow fuel in a gravity system. I use the small lawn mower type filters that are designed for gravity feed systems. I also often have to remove the hose from the carb inlet and run some fuel into a catch can to start the fuel flowing, then quickly slide the hose onto the carb fitting and tighten.

Hey Guys,

Well, I think I have the problem solved. It was the float level after all. The float was set too low. In other words when the top was turned over, the float should have sat level. It actually sat at a 45. I re-set the float to level, put the carb back on, and it works great! No more cutting out. Apparently with the float setting as it was, it wasn't putting enough gas into the carb. The level was low enough that when I went up an incline, it tried to die because it was deprived.

Again, thanks to all who tried to help me. I know it's not easy to diagnose problems without actually being there.
