How can I get my Quadra 35 equipped with a Bennet muffler to run quieter? There does not seem to be ANY baffeling in the Bennet muffler. The engine is mounted inverted on a Balsa USA Cub and it's too loud. Can something be added to the Bennet muffler pipes to reduce the noise?

I'm Looking for the stock muffler for a US35 or 41 gas engine. It's the black, stamped original style muffler. New or used. Anybody have a stock muffler to sell?

Someone must have replaced the stock muffler with a better one and have the old one kicking around.

Thanks, Wayne
