Guess what.. another issue

Postby pokitisme » Wed Sep 04, 2019 11:54 am

So I put a brand new carburetor on my 1948 Farmall h. I have gotten the bottom and top screw adjusted on the carburetor so now it starts up every time. Here is the issue I'm having. Whenever I try to put it under load at high throttle. It will go a little bit and then die. If I try to go up a hill in first gear it will almost die in any other gear it will definitely die before the top of a very small hill. if I try to go up any Hill with an implement attached it will definitely die. It starts to go up the hill engine sounds normal but sputters out as I get higher and higher. I could probably make a YouTube video and put it up on my page. for others to see if you guys want me to to help me diagnose this issue. I believe the top screw is set to 2 and 1/2 turns out the bottom screw I am not entirely sure but I know it's supposed to be one and a half.

This sounds like a fuel starvation issue that may have nothing to do with your carburetor. When it dies, make sure it isn't going to roll away on you and immediately loosen the fuel line at the carburetor. A steady stream of fuel should run out. If it doesn't you either have a blockage in the tank or in the sediment bowl (or a kink in the line restricting flow). I would check that first. This all makes sense as when you go up a hill, the governor will increase the throttle position which will kill the engine if not enough fuel is available.

If you can record a video and post it, that will help diagnose.

Did you ever do a 100% engine tune up?

Low fuel level in gas tank?

On my H you have to have several gallons of gas in the tank or else any hill will cause starvation. If you are trying to debug it with only a gallon or two of fuel that may be your problem. Otherwise it sounds like possibly the governor isn't opening the throttle correctly, recheck those adjustments since you replaced the carb,

Could be fuel, but I was thinking like Rick that the governor may be the issue. Have you checked the governor or did any work on it lately?

I have never done a 100% tune up about all spark plugs are firing. The gas line is a home-built rubber hose gas line. The tank is nearly full with gas. There is good gas flow to the carburetor. The video is YouTube it's listed as "Farmall h test run"it could be possible that the governor might be slightly off but I do not believe it is. The adjustments on the governor are different now with the new carburetor. It used to idle at three notches now if idols about halfway.

I haven't watched your whole video yet, but it sounds like the tractor is not running on all 4 cylinders. The oil puked out of the exhaust and all over the hood may have something to do with that. You need to pull all of your spark plugs and see which ones are dirty and assess why it is misfiring. Do this before you make any further carburetor adjustments or start messing with the governor.

When was the last time you did a complete engine tune up and lub/oil job?

My guess on oil being pumped out between the manifold and exhaust - - rings allowing oil to be pumped into the combustion chamber. This would foul the spark plugs, thus lack of power.
I'm pretty sure you problems are related to your previous post on the topic.

Put a complete engine overhaul in your budget.

With that much oil blowing out, I fully agree.

Definitely not firing n all 4 cylinders. Be sure the plug wires are in the right order, and/or check plugs to see which ones are black and fouled. That engine is not well at this point....

yes I understand what you're saying but that is not oil all over the carburetor. My cousin bent the Damned exhaust pipe. LOL. For some reason when the pipe is bent like that it is heating up all of the creosote and other accumulations from years past. It's causing that stuff to melt and drip down on the carburetor. That is definitely not oil.

as far as I can tell the engine is still in full operation of shape. I think what the problem is is my gas line. As stupid as it sounds I have used a rubber gas line but it is not in the same configuration as the original metal gas line. I can sit there and let the engine run on high throttle or low idle for long periods of time without one single issue. when I start to put it under load and up a hill or even just up a hill by itself. That's when the problems arise. like I said as stupid as it sounds I think it might actually be the gas line which I'm going to have to invest in getting a new metal one with the little turn in it and everything else. If you watch the video my gas line is not in the same configuration as the metal line. I think that little twist in the middle line might be what's causing the issue.
