A little help/insight, please.
I bought a 59 Oliver 880 with a TSX775 Marvel Schebler Carb. The listings and rebuild kits and shop manual say this carb is for 550/660, though a Steiner listing hints that 880s did have a large body Schebler at some point.
It is running lean, and a rebuild kit helped some but not a lot. Can't get it to run rich, and have to run with choke pull out 1/2" to get it smooth.
Is this just flat out the wrong carb for the tractor?
Since it is large body, could I size the venturi, idle, and nozzle for an 880, maybe borrowing that used by a 1600?
Or should I ditch it and replace with the aftermarket Zenith?
Thanks for the thoughts.
