"I am learning maybe more than I wanted to know about 2-cycle outboards, trying to resurrect an engine out of storage. Thanks to this group I haave cleaned carbs, #2 had float stuck wide open and disintegrated gasket. Finally got it started but has no idle and linkage seems a little screwy.
Also checked compression, #1 150, #2 135, #3 125 think there is head gasket problem? Will this cause ldle issues?"

"w/25psi diff,there's something going on...i would try a decarb first---frees up,sticking rings..u really need a factory service manual to help w/all the link and sync adjustments...u may do a decarb 2-3 times to help it.."

the linkage issue is another matter I know forward, neutral, reverse, but I do not have a fast idle is this a linkage adjustment or a remote failing? Also I can start in any position. Any suggestions?"
