Anyone running the MACS 6720 on this engine? The MACS web sites says it will fit but no guarantee when used on a gas engine. Is vibration an issue.
My engine starts easy, runs great and makes plenty of power. I'm done with the 3 piece muffler. What a PITA to keep it together.
Ha........NM. Should have searched first.
