Hello!
Although I am newish to the Super A, I am not new to figuring out mechanical issue or carbs. My favorite car was a 77 Chrysler Newport Royal with a 383 4-bbl. I spent a lot of time loving on that car, and she ran great! Left everyone in the dust, too! (I put my money in the engine and drive train, not the bling!"
So, to the Super A. I believe it is around a 53. I'm not sure how to tell what the age is.
SHORT HISTORY:
This was my grandparent's tractor, until my grandmother passed away fourteen years ago. My brother was 'running' the tractor every once in a while, just to keep it in good shape.
Now I have a need to use the tractor, but have found out that it sat for eight years with gas in it!
When I found out, I was FAR from happy!WHAT I HAVE DONE:
Needless to say, the battery needed to be replaced. I also pulled the fuel strainer and flushed the tank...three times...to get the junk out of it. It's still not one hundred percent, but the fuel is cleaner.
I replaced the strainer as a whole. It was easier than getting the pieces I needed to fix this one (Bowl was cracked, screen was torn, gasket cracked).
I removed the copper line and put a rubber 5/16" hose in it's place. (Sorry about that, purists!) I'll probably go back to copper, once I am past this headache.
I rebuilt the carb. The old float still works fine, so I didn't replace that, but it DOES have a new needle and seat in, and I flushed it well with carb cleaner and air.
I cleaned out the oil bath air intake. What was in there was more like tar than oil.
Pulled the plugs, cleaned them and gaped them. They looked pretty good, so I was ok with leaving them for now.
Nothing wires yet. I have good spark.
Points look ok. They probably need a filing, though.
THE PROBLEM:
I can start the engine with the choke, and then push it in and it will run fine. Far better than I expected. And it will idle for fifteen minutes without issue.
BUT, if I try driving it around, I can get MAYBE five minutes, then it stalls - like it's out of gas. (There's three gallons in the tank)
If I let it sit for about five minutes, it will start and run again for four or five minutes. Idles longer.
I check the ID of the copper tubing. It is less than the ID of replacement nipples I put on the strainer and carb.
THE QUESTION:
Have any of you seen this issue before? Can you give me any ideas of what else I should be checking?
I have considered a low pressure, 6 volt fuel pump for the tractor, with a pressure regulator to drop the pressure down to under one pound, but I really don't want to corrupt the tractor any more than I have!
Any HELPFUL feedback is appreciated!
