Engine runs rough in cold weather

Post by CAPTAIN-D »

Anyone run heat from the headers or muffler to the ventura on the carb to keep the moisture from freezing up and causing the engine to run rough in cold weather? If so I would like to see how it was done.Thanks.

Here is a previous discussion on it, should be easy to do , construct a aluminum shroud around the exhaust system and plumb a piece of scat tubing to the carburetor air cleaner housing.

Most of us AV motor guys here in Utah run those hot air exchangers from the headers to the carb. i think they work great.
