Quality carb kit?

Postby FrankenCub » Wed Jul 12, 2017 9:05 pm

Can one of you recommend a quality carb for a 154 with the IH carb?
I thought I had governor issues so I dug into it today, that seemed to be adjusted properly. Once I disconnected the linkage again to check throttle operation I found it has a catch in it, not allowing the governor to open the throttle and in the end not allowing it to keep the proper RPM.
Looks like I'm going to need a new shaft and bushings in the carb body. Honestly, not looking forward to doing that lol.
I've been putting it off but now that we will be moving to new property I'll have about a 10 mile drive with the 154 so I guess I better get around to fixing it.

Check McDonald Carb website, they have individual parts or complete kit.

UHaul rental has a 5x9 utility trailer with loading ramp that is not expensive and works really well for Cub and LoBoy tractors.

Thanks, I'll see what they have for parts. Got to thinking today I really don't need a rebuild, other than the throttle issue she runs great. Maybe I'll just pick up a new throttle shaft, gaskets, and a bushing kit. If it has bushings.

Can't use a Uhaul trailer. My truck has a pintle hitch and is pretty tall, military CUCV, and I don't want a receiver hitch on it.
The throttle issue needs to be fixed before I can use it at the new property anyway so might as well fix it and drive it over. Cheaper that way too lol.

McDonald has the replacement throttle shaft. No bushings. The IH carb uses felt donut shaped seals to keep dust out. McDonald also sells the seals and retainers.

Thanks ;) Glad there isn't any bushings lol, I'm good at messing them up. If the rain holds off I'll get the carb pulled and see just what is causing the catch. Hopefully it's just the throttle blade hanging up when the shaft rocks over and hasn't done any other damage.

With the engine not running, and you disconnect the throttle cable at the forward end where it connects to the governor and the "yoke" connection on the throttle rod from the radiator to the carb does the rockshaft including the lever where the governor spring attaches all move freely without any binding or restriction? If not you probably have a problem with the lever on the shaft coming out of the governor.

Yea, as Stan says, many times the governor rod to the carb will get bent a little, and rub against the engine block, ever so slightly, but if there's a little rust or dirt, it will hang up and cause the enging to hunt or run rough. Sometimes it's hard to see, especially if the tractor has been painted and there's paint gobbed inbetween the two pieces. I've fixed many just by taking that rod off and scraping the paint off or bending it a little so it doesn't touch the engine block. It's more likely that than the throttle shaft in the carb binding up.
