Cushman Cub 2 hp Carb Issue

Dave Neal

I recently brought home a Massey Harris model 14, eng # 6540,750 rpm. These specs are from the brass tag. Upon research I believe this is a Cushman Cub manufactured for Massey Harris. The carb, or fuel mixer, is a puzzle and has been significantly damaged and I would like to replace it. I believe it is made from magnesium or some other metal. I found one on "Engineadds"and I believe they are associated with SmokStak. The puzzle is that my carb and "intake manifold" are threaded--1- 1/2 inch diameter and 18 tpi. The carb on engine adds is brass but appears NOT to be threaded.
Any help would be really appreciated. Thanks

Hi Dave.
They used both threaded and smooth carbs not really interchangable. How is yours damaged, maybe it can be repaired?,

The 'pot metal' (zinc alloy) that Cushman used for their carbs was a crappy metal. It distorted with age, was very brittle (tended to break), and it developed stress fractures that rendered them useless. You might try a want ad in the Engin-ads section of the Stak, or see if one of our engine parts sponsors has a replacement. Good luck!:O
