Hello all,

Was talking with a coworker of mine yesterday and he learned I was into antique tractors. He stated he has a Case/Ingersoll 448 with an 18 HP Onan, and is in search of a carburetor (his father pulled it off to rebuild it and it's been a few years and he cannot find it). He stated the carb is a DD13. With the little research I have done, that makes it a Marvel Schebler carb, I believe?

Any info in locating a carb would be helpful, and I can pass the information onto him. Thanks!
 
Hi Boomer is your best bet, you can see what e bay has but they are pretty rare and many times are in poor condition ( that is the same carb used on the Sears Suburban SS16) a DD15 can be used also. Chances of any of the small engine stores having one a about zero.

Boomers may be your best bet.

Since Cummins (the diesel engine people) bought ONAN years ago Cummins has become about the only place to get parts for a lot of ONAN engines.. I had an old 1000 watt ONAN generator from the 70's that had a 5 hp Kubota engine. They were the only place that I could get a new carb for it and I was not about to pay Cummins $650 for a carb to fit a 5 hp engine.. The generator got trashed.
