Hi Guys: Just modified a 26CC homelite. The problem I am getting is low RPM's...only 5,400 witna 17X8 prop. I am testing with the stock muffler. Does this may be the reason for low RPM's? Thanks

Note: I installed a CDI ignition on it and timming seems to be right.
Take the muffler of and see if you get a RPM increase. You may have to retune the carby a touch! Capt,n P.S. Most engines run good at 28 degrees BTDC
