Colt Case Ingersoll Garden Tractors

Well the 446 has developed an issue. I used it to gather hay bales yesterday and it ran great, not so much as a sputter. Today on the other hand, I started it up and went to move it and it died. Upon initial start up it throttled up fine but now it will just idle, if you try to give it more throttle it will immediately die.

I didn’t have much time today but I did take a quick look. Here what I know.
I have spark.
The fuel pump is working.
I can get it to idle but can’t give it throttle.

I’m thinking my next step is to pull the intake and carb and look for problems or leaks. I’m curious to know what you guys think. Any thoughts are appreciated.

Don’t want say this, but, out of gas ?


Noel

If it starts and idles fine but stumbles/misses as soon as the throttle is increased the condenser has failed.

Bob

Bad ground on the condenser will make it run funny.

@propane1 @myerslawnandgarden thanks guys.
I does have gas and the fuel pump is pumping. I hadn’t thought about the condenser I’ll have to see if I’ve got one and switch it out.

Even if you don't have the correct condenser, you can take anyone that you have and connect it at the negative terminal of the coil and ground it where convenient. That will at least tell you if the condenser is the problem.

I found a new condenser on the shelf,I think it’s for my Farmall Cub. I wired it in and it made no difference. Except now it won’t run at all. I pulled a plug to verify spark and it’s good, but the plug was dry, no gas getting to the cylinder. Since I know the fuel pump works I decided to go ahead and pull the intake and carb.

I think I found the issue!
That’s where I had to stop for now. I’ll have to clean up the intake and reseal it and I guess I might as well go through the carburetor while it’s off. At least now I know what’s going on!

That's some good troubleshooting! Good thing it didn't overheat and bend your heads. A dab of grey gasket maker and you're back in business! Or?

Thank you. I don’t think anything got warped it was running fine when I shut it down. My plan is Permatex grey and then Seal all over that. Noel has me hooked on it!
Seriously though I’m impressed with Seal all enough that i have no problem reaching for it on stuff like this.

Sounds good. Is Seal all ok with the temperature of the intake?
