i bought a used powerhead with all ignition parts and fuel componets.it has a intermitit miss at idle and on acceleration it hesitates. at about 3/4 throttle to wide open theres no change in rpms but you can hear the sounds of the carbs change. my old powerhead ran at 5600 rpms this one won't get over 5100 rpms. i have put all my original electrical parts on and its firing good . have cleaned the carbs ,throttle plates and checked the reeds . i also changed the fuel seperator filter . it has 125 lbs comp. on port and 130 on stb. i,m stumpped . any suggestions????? the only thing i can think of is putting my original carbs on. one thing i did notice was the 1994 carbs have low / intermediate /and high speed orfices. but my original carbs from the 1996 has intermediate and high speed orfices and a ajustment screw for the low/idle speed. are the 1996 carbs a better design??? just because thier newer doesn't always mean thier better???

Did you check the timing after changing all of those parts?
