OK. Well at least we have isolated the engine starting problem to the carburetor. Then again, there is a strange clunking sound whenever you shake the saw. Mufflers for these saws are all discontinued. Sounds like the guts of the muffler have all come apart and are rattling around inside the muffler housing. Is that something to be concerned about? I figured I would just let that slide until I got the engine to start running. opcorn:Why a 100 buck fix? Get the carb off, get the number, order the kit by make/model of carb. Pay attention to which bits go where. Clean it out good with carb cleaner, and the little screen inside is sorta critical. New lines, etc. Should be under 20 total, not 100.
