hello,
I am stumped. I have a 1986 225... new stator, timing base, VRO pump and power packs, carbs rebuilt, good compression (almost 110 lbs per). It idles a bit rough at times and sneezes and sometimes stalls. This is corrected by bliping the choke a bit. Secondly when i throttle up, it will let me go about 1/4 throttle, then start to stall, then I blip the choke again and then I can procede further with half to full trottle. It will allow me to stay above that throttle point and within that throttle range with no problem. As soon as I drop back past 1/4 throttle and try to trottle up again, she starts to stall until I hit the choke. Sounds like the low speed circuit. Thats what I thought. I took the carbs apart and cleaned them again and even ran a wire through all the emulsion tubes and thru any hole I could find. The problem doesnt go away. I even ran an external fuel tank to weed out a fuel/air leak and that had no results. The guy at the shop thought it was the emulsion tubes so I cleaned them with a wire and there is still no change. As a last resort I am thinking of jeting the carbs richer. I think there may be an air leak somewhere that is only affecting the low speed circuit. Is it advisable to jet them a step up? Also, which is the current low curcut jet... the 14 or the 20? and if its the 14, should I go to # 15, 16, 17? Fuel is new. Have a water seperator. Just a lean flat spot that I do not know what to do with. Please help.
