[merc]

.....or lack of.
I have a 1980 GN400 that we have been trying to get running again, after years of neglect.
We have it so that it will start with one kick. And it sems to be fairly smooth. However I can not seem to get it to go over 30 mph.
We have changed the oil, regapped the plug, cleaned the carb's reservoir, and cleaned the air intake.
Any suggestions?
thanks
