I'm going by the name BudTuba because among other things, I am a tuba player in a Dixieland Band near Rochester, NY. I live on 6 acres and have been doing "gentleman farmer" things out here since 1972. In about 1978 I bought a 1954 Farmall Cub with several accessories: land plow, sickle bar, cultivators. Later on I bought of front push blade and use that in the winter to plow my driveways. I also bought an belly mower of the Mott type. This has a horizontal shaft and many small blades attached to short rods welded to the shaft. This works well with regular mowing of grass, but the height of the Cub is a problem when clearing under trees. Consequently, I bought a Ferris mower that I use to mow the roughly 2 acres lawn.
I rebuilt the engine in the mid-1980's and somewhere along the line bought an International Cub carburetor to gain power. I still have the original carburetor that I would be willing to sell if someone is trying to rebuild one and wants the original parts. I also converted it to 12 volts negative ground and have a charged-capacitor ignition on it. Since the starter spins over faster than with 6 volts, this really helps starting on good days. I have to nurse the engine with the choke control for a minute or two for it to start and run smoothly.
Herein lies my problem. Even when warmed up, I sometimes have to pull the choke out when starting up or pulling tree, etc. I do not understand why this happens since the governor seems to be working OK, but possibly I need to readjust that. Any help on this issue would be useful to me. I will repost this section of my message as a seperate problem, considering that some people are less likely to look through the new member's posts.
I would be glad to share my alterations made or other problems with somebody who contacts me via this board. We could then exchange phone numbers for more direct communications.

Welcome to the Forum Bud. Lots of great folks willing to share their knowledge.
Not sure if you have recieved your answer yet, but it sounds like the enigne is starving for fuel. Have you pulled the metering jet out to see if you have trash in it?
Let us know how things work out.

Welcome to the Cub Community
Yup, definitely sounds like fuel starvation. Most likely this is a result of dirt/gunk/crud buildup probably originating in the tank and finding it's way to the jets. Please read the Cub Pointer Text below and follow it to the Welcome Wagon. There are a number of links there that will assist you in solving the fuel problem. Also, don't forget to check that the vent holes in the cap are clear of dirt and buildup as well ok? That can be a little thought of problem. There are a number of really good resources here including the CBoK and others, please do investigate them.
I have a feeling that you are describing the IH 3/4 Updraft Carb when you state: I still have the original carburetor
and are talking about the Zenith when you state: International Cub carburetor
Both of these carb diagrams can be found in the TC-37 Series Parts Catalogs and will help in identifying and cleaning the jets.
Hope this helps and again, Welcoem

Hey Bud I am near Oneonta. Couple of guys up your way. Take the main jet out the brass hex head in the carb bowl. Push a soft copper wire through it. Then blow it out with compressed air. This will cause the number one suspect. Generally if this is the case you can get it to run stronger with the choke partially or all the way out. Another possibility is the timing off or even valve adjustment. Plugged inlet at the tank, plugged screen in the sediment bowl as well as a plugged screen in the inlet for the carb if you still have one are suspect as well. Some have added filters into the fuel line that will not pass enough fuel at one time to run well under a heavy load. A misadjusted float in the carb can do it it as well.
I know this is a long list but start at the top and work through is till you fix your problem. This list is not all inclusive for a failing coil or condenser may cause your problem as well. This is not to say the coil or condenser has failed completely but sufficiently so as not able to handle a full load. This is rarer the the other possibilities.
