I use this site when i find a carb to figure out what tractor it came off of... Not saying its 100% right, but i have not had any problems so far...... Look at the YEAR on the left, then verify the tractor model ---- carb manufacturer --- then carb number

Yup, that's one of the sites where I did some of my research. I used just about every carburetor related site that comes up in the first 50 pages each using dozens of different search terms. I found many sites that contradicted each other in various ways.

Here's an extract from an old Zenith PN/price list. Seems to show PNs 09705 and 09706??

I believe the 9705 and 9706 carbs are from the C, not the CA, so they would be older. They have almost completely different sizes in the jets, vents, and venturi compared to the 11141/11142 that was used on the CA. I imagine those "sized" parts needed to be changed for the CA's higher engine RPM and power output.

Do you happen to know the serial number of the CA with the MS carb? Curious if it is an earlier one.

I have 2 CA's, one with a MS carb(1953) and one with a Zenith(1955). The tractor with the Zenith runs like a scalded cat. The other I cant seem to get right. I'm planning on swapping to a Zenith if I can't get it figured out soon.

Check out your carb my CA with the M-S has run perfect for over 20 years that I have owned it.Previous owner I knew well had the tractor for over 20 and don't think he ever touched the carb.On AC tractors and other brands of that era I'll take a M-S over a Zenith

Jed... what exactly does the CA with the MS carb do that you dont like ??... jet pluggage is a problem if you cant get full throttle.. Governor adjustments can be a problem if there is bad throttle response ... etc.

It dosent seem to have the same power as the one with the zenith. It runs way hotter will spit and spudder. it has new plugs, wires, cap rotor, points, condenser ive been through the carb a few times. i have replaced the intake gasket, and torqued. the manifold is not warped. I plan on pulling the carb and swapping with the zenith to see if its the issue or something else. not sure what else it could be.
