My grandfather is in the final stages of restoring a 1970 SS12. He had it running like a top when he started doing the restoration about 8 months ago. The engine was rebuilt last winter, and maybe had 4 or 5 hours on it since then. The tractor for the most part has had an easy life. But when he got it together last weekend we couldn't get it to run. No matter what we do. Now ive search and have found the carbs for like 150-200 bucks because we want to kick the problem in the butt, but he doesnt want to spend that amount of money after already putting enough money into it. Would we be better off spending the 30 for the carb rebuild or just a whole new carb? I perosnally own IH Cubs so have no idea about these sears machines. Any info would be greatly appreciated!

Welcome to GTT :wave:


If there is nothign seriously wrong with the old carburetor I'd rebuilt it , I would need to know the carb numbers off the body but I do stock the kits for them.

Other option is converting them to a new Tecumseh made carb which is $100


If your air cleaner mounts like this picture it will be a bolt on replacement

Can the original carb be rebuilt as mentioned


Rumor has it that the carb for a Kohler K321 (14 hp.) or K341 (16 hp.) will bolt right on

Around 20 to 30 dollars off Ebay shipped to your door

According to this thread 




I believe you will need a Kohler air cleaner for proper choke operation
