My 4cyl Ford 4000 started running rough. I shut it down and left it. Fast Forward a few months (to yesterday), it restarted once, I left it to warm up, it ran for about 3 minutes then quit. It sounded a couple times like it wanted to turn over again, but it never did. It had a tune-up, about a year ago, ran well, until it did not. It has ethanol-free gas in it and I threw in some Heet gas dryer as it was sitting, covered, but sitting for those last few months.
I pulled the plugs, they looked clean, though I could not see the spark (maybe because of the sunlight?) but I was holding it wrong, grounded myself and felt a jolt. The plugs seem fine; wires seem fine. Compression was strong - no tester - just felt it blowing out the spark plug hole with force.
Perhaps the carburetor needs a rebuild? When my ATV started running poorly, rebuilding its carb fixed the problem so why not the tractor... (as my logic goes).
So digging around, leads me to believe the carburetor could need some attention. The sediment bowl was filled with junk, so cleaned it out. The screen had some junk, I cleaned it out. I pulled the drain plug and some fuel came out, not a gushing stream but it was flowing. When I put the plug back in and sediment bowl back on, the sediment bowl filled up quickly. (I have an inline fuel shut-off 1/4 turn valve in the line).
Anyway, the carburetor is a Marvel-Schrable - but the tag was removed. It was not a brass plate, but a metal tag attached with by one of the screws in the carburetor body.
The ONLY identifying marks I can find is a 10 that was part of the casting and the name Marvel-Schrebel that was also part of the casting.
In the absence of an identifying tag, is there a reliable way for me to identify the model of Marvel-Schrebel carburetor that is on my tractor so that I can determine the correct rebuild kit?
Here are a couple images of the carburetor in question.
