ford 2000 3cyl fuel starvation

[kenbob]

I love my ford 2000 3cyl and has been mostly trouble free engine wise. I am now having a fuel starvation issue. It runs fine at 1800 but push it beyond that or up hill and it now wants to cut out after running at that speed a few minutes. THe filter in the glass is good. I understand there is a filter into the carb and filters at the fuel pump. Both are incredibly hard to get to. I think the carb filter is on the back of the carb and would like to attack that first, but is there any secret on how to get at that? I also noticed their is a valve at the bottom of the carb (Holly). Doesn't look like a drain valve? Is that a mixture valve. T-type screw in. THanks all in advance.

what are you doing that you need to push it past 1800 rpms? Hill problem sounds like a float issue!

It shows 2000 rpm and actually will rev to 2200 when wide open on the road. It isn't just hills. On the flats past 1800 rpm it does it after the carb gets starved. Ease it back and it straightens out. but 1800 on a steep hill causes same thing. I am pretty certain the carb bowl isn't getting enough fuel. for running past 1800 as when you start out all is good. Only after going a while does it act up. Cut back to 1600 rpm for a few minutes and it is good again for a couple of minutes and then starvation sets in again.

You are going to have to bite the bullet and go after those issues are they will keep on defeating you.

You can shine a light into the fill neck of the tank to see if there is a lot of gunk in the tank. If it looks clean, then it still might be the screen on top of the shutoff valve, but not that likely. That screen is actually pretty easy to access by removing the shutoff valve, but you have to drain the tank to do that. The filter in the back of the carb is inside the connection where the line from the sediment bowl connects to the carb, also pretty easy to access.

My experience is with 4000 series 3 cylinder gas engines, I think the 2000 system is basically the same tho. There's a screen in the fuel tank attached to the valve, there's a screen in the fuel pump which is located behind your generator which you'll want to pull to gain access (your tractor still has its fuel pump, right?), there's a settling bowl/screen in the line behind the carburetor, there's a screen at the inlet fitting to the carburetor. And there is the carb itself which, despite all the screens, can accumulate nasty stuff in the bowl.

Clean all the screens, drain the carburetor, and see if there is a difference. The fuel pump is 'low pressure' (3 psi, I think), my carb has a plug opposite the inlet where I can attach a gauge. Yes, the fuel pump filter is a bit of a PITA, but not 'incredibly difficult', same with the carb fitting. It's a 7 minute operation to pull the carb off and take it to the bench.

Also wouldn't hurt to check the dwell, somebody here made the comment that '90% of carburetor problems are electrical' and there is a grain of truth to that.

Your picture was helpful. At least I know what I am looking for. You are very knowledgeable. Is that t handled valve in the bottom of the carb an adjustment or just for draining? Thanks.
