Thanks immensely for all your help on this problem with my dear old 2N ('Beulah'). After nearly 30 years of suffering with this issue, she's *finally* working right again! The people on this forum are amazing!
I can't tell you how exciting it is to drive my old girl anywhere I want to now, without worrying about which way she's leaning. I actually took her down across the side-hill of our hayfield last evening, leaning hard to the left all the way, and she purred like that famous kitten!
I ended up jacking and blocking her right side up about 8" in the barn and checking her over while up on the blocks. Made it a lot easier than dealing with this out in the field, that's for sure!
Even after rebuilding the old carb, as soon as I turned the gas petcock on, fuel overflowed out the air intake, so I knew, finally, that the float was definitely the issue.
Coated the floats with candle soot and carefully reinstalled them, then turned the carb upside down and back upright a few times while leaning it left (had already checked them for leaks).
With no marks from the floats rubbing the bowl, and having checked everything else about a dozen times, I bit the bullet and ordered a Zenith #13876 (Btw, YT had the best price I found anywhere)
I'm really impressed with the Zenith so far; this Ford runs better than it ever did! Smooth acceleration from idle - something I could never get 100% right with either the original or replacement M/S TSX33 - and much smoother running all around.
I should've done this a couple of decades ago!
It has always just boggled my little mind that two M/S carbs would have the same issue, but they did - one brand new, right out of the box.
And I appreciate that the Zeniths are still made in the USA. That's rare these days.
Anyway, Thanks again, you guys, I *really* appreciate all your amazingly generous help. Guess my wife's right, I don't get out enough, but I'm so excited to have my tractor back, I'm looking for any excuse to use it today!
If I can ever be of any help to any of you, please get in touch.
God bless you all,
New Albany, PA
