    twin 800 challenger high idle help

    Hey guys just got a challenger 1800 with twin 110s in it and cant seem to get the idle to come down past 3200 out of the water, unless i pull the choke, I have cleaned the carbs, and there is no gray fuel lines, it just sits at the rev limiter in neutral, i havent even put it in the water or on the hose yet. It starts right up no problem both motors but they just rev out at like 3200 or so. I am getting so mad any help would be awesome!

    yes both do this, i have full adjusted the idle screws and everything, both motors have been sitting for 3 years but have get comp. and everything seems fine, i dont know what i am over looking as i have adjusted the throttle cables, do the oil pump cables need to be adjusted to pull the carbs closed even more, cause it seems that the carbs are connected to the throttle cables this is the issue, i never worked on a boat like this before i have done tons of the 800s in the skis.
