got a 24" redmax cht model. it starts fine, bogs down at wide open throttle. checked fuel filter (tried running without it). cleaned spark plug (didn't have a new one). i can get it to rev by feathering the choke. tried fresh gas. i couldn't figure out how to remove the cover to get at the muffler to remove/clean spark arrestor. it's got one screw on the top, and removed the plug wire, somethings hanging up.
