1993 JOHNSON 70 HP WILL NOT RUN IN IDLE

VJ70TLETS

problem im having is if you put throttle into fast advanced boat will run on all 3 cylinders great ,but if you start at idle you have 1 spark or none and it will never start. I did replace power pack cause i had no spark at all previous and i used a new Johnson oem. any help or ideas would be great. ive been going through the cdi trouble shoot and i hope to find it soon enough. thanks for any help

How did it run for you last season ?-----Post actual compression values here.----And does the telltale hose come off the side of the block , or off the top?
