Throttle linkage

Postby Dominic » Tue May 23, 2023 12:17 pm

I have a late 70s cub that I am in the process of bringing back to life. I can’t seem to figure out how the throttle linkage connects to the carburetor. I believe there are missing pieces but can’t find any diagrams to lead me in the right direction. Any advice helps. Thanks

Dominic,
Pictures are worth a thousand words.
Late 70's Cub could have an IH Carb or a Zenith Carb, two very different linkages.

Hi,
Cubs with serial number 248125 and above originally have Zenith carburetors. 248125 was made in mid 1975.
Below that serial number they had IH carbs.
Below is a page from the Cub parts manual showing the governor and linkage. Number 7 in the pic, the spring, goes at the governor housing.

Peter, the rod ahead of the carb, number 1 in the parts pic, has the same part number in the Cub parts manual from 1949, as it has in the parts manual from 1979, both manuals are on here. I don't know what you meant is different.

The Zenith uses a choke cable, the IH carb uses a choke rod.

Below are pics, from TM Tractor Parts, for you Dominic, to identify the carb.
The 1st pic is an IH carb.
The 2nd pic is a Zenith carb.

Thank you Glen. Based on the pictures, I have a Zenith carb. However the link you provided gave me the information I needed. Thank you for your help
