I changed plugs, coils, sparkplug wires, new filter element, new gas with some sta-bil added. I can get to wide open throttle now but it's slow to respond and still kinda sputtery around half throttle when i'm both powering up and powering down.....i'd like to clean the carb but i'm not sure how...i can't figure out why the throttle response would be slow?? ideas?? Thanks for any help yall!! 
Oh yeah, it's an 1986 25hp merc tiller 2 stroke long shaft.
