Carter carb 1.75 interior measurement across bottom opening . Should be a 261 carb at that measurement. The vacuum hole on the base of the carb looks to be in the correct area for a 235 and centered on the wall of the carb at about the 10 o’clock position. Also below the base of the carb was a steel plate in the shape of the base gasket only squared off on one corner. 1/8 “ thick. No hole for the vacuum hole on the carb base on this plate. Base gasket was a 261 gasket. The one with the four notches. The notches on the gasket doesn’t line up with the vacuum hole on the base of the carb. What do I have here? Should not the gasket at least allow for the vacuum hole ? Thanks | | | | | Joined: Jan 2014 Posts: 3,677 'Bolter | | 'Bolter Joined: Jan 2014 Posts: 3,677 | Rochester made a B specific to the 261. Carter had a YF model # for a 261...but never actually produced it (according to some info carbking has posted here).
Are you sure your carb is a carter? Posting some pictures would help if you can.

I guess my questions are not so much for the carb but the carb base which bolts above the insolator. And i got to start posting pics thanks | | | | | Joined: Nov 2015 Posts: 84 'Bolter | | 'Bolter Joined: Nov 2015 Posts: 84 | Update . After a new set of plugs she started right up.one bad plug wire and numerous dead plugs. She started up but no idle.just ran on choke. After fixing a vacumn leak she idles like a champ and starts easily. | | | | | Joined: Nov 2002 Posts: 2,763 Carburetion specialist | | Carburetion specialist Joined: Nov 2002 Posts: 2,763 | Isn't it amazing how a good electrical tune-up will solve a "carburetor" problem?  Glad you found the solution. Jon.
