Hey guys.
I went out today and ran around abit, then the engine(1990 force 120hp) started idling poorly. After messing with it for a bit with no improvement I decided to limp it in to the dock and then home. After popping the hood I noticed oil around the plugs and then I realized I forgot to tighten the brand new plugs in. Yup ...well my question is
is this going mess anything up? They were just finger tight and yes the wires were on
thanks!

Tighten them up and go boating. The motor will run much better.

Yeah - Fix it. LOL

The only thing I know about Forces is by watching NHRA nitro drag racing. :D

If it runs better with the cover off??
Then you probably have a problem???

There is a rubber bellows between the driveshaft housing and the rear cowl.
Sometimes they get moved?? Sometimes they split(usually on the bottom where you can't see it) and leak.
Sometimes the factory clamp rusts away??

Take the cover off, go for a ride.
If the bellows is ok?? then the spacer plate's gasket could be leaking.
I fixed mine with a blob of sillycone, until I could get back to it(never did) :)

Thanks Jerry

I took it out today again after (duh...loose plugs) in hopes of recalibrating the carbs since I reinspected them after the engine developed an idle sneeze or cough. I paid close attention to "Franks linc and sync" sticky but couldn't relieve the sneezing. I thought maybe the slight exhaust leak may have a lot to do with it, I decided to deal with it at a later date. After bobbing around for a couple hours and trying various adjustments to shaft tower idle control screw, air screws on the carbs, cam follower arm adjustment and the little plastic roller thingy- it finally came to me...I decided to adjust the lower carb with the little plastic roller thingy slightly more forward/ open than the top carb...THIS IMEDIATELLY CURED THE SNEEZING IN frwd gear/idle speed...the motor calmed and became noticeably more responsive to the throttle. I am still having a lack of throttle but at the moment im happy with 44000rpm/29mph (according to gps), throttle maxed out. Sorry admins; probably should've began a new thread...

SORRY for the hack!

Jerry, where exactly is this spacer plate/gasket?

Don’t quote me but I think the spacer plate Jerryjerry05 is referring to is the “spacer” right bellow the block, where it connects to the lower. On mine; going up; there’s the lower case then gasket( or maker) then a spacer plate approx 1”thick which sits on perimeter of the lower then another gasket (or gasket maker)
