[QUOTE="Jake11, post: 362427, member: 14133"] been a few days since i messed with it but after taking a good look at it i noticed that the throttle follower arm was already contacting the control cam or whatever its called when the throttle was in the start position by about an inch past where it should be at that point. loosened the screw and set it so it was just contacting that cam at the start position and it fired right up and idled like a dream for about long enough for me to set the idle screw...... then started running rough and vibrating.... pulled it out of the water and popped the plugs out. spark on the top cylinder no spark on the bottom cylinder... the coil i didnt replace popped on me... showing open from where the plug wire attaches to the ground on top of it the good one shows short. i knew i should have not been a cheap skate and ordered both of those coils. oh well lesson learned. new ones on its way so hopefully i'll get it on the water by weekend.
