clogged jet due to something like dirt in the tank? partially plugged silencer somehow...i looped a bike once and didn't notice my silencer was partially clogged until performance sucked. worn or chipped reed? plug starting to go bad? any substantial elevation or temp change halfway thru the day?

i bet you've got junk in the carb bowl and everywhere else in the carb. i'd take out the reed valve and make sure its clean as well
