Re jetted my 1990 Force 120 hp L Drive engine and it helped a bunch with power. Ever since I can remember I have had a running issue with this engine. It will run like a champ for about an hour (from first start up) then start running like crap. Starts missing and sometimes will only hit 3000/4000 rpm then all of a sudden jump right back to running great. Checked all wiring and am baffled as to the issue. Installed a fuel/water separator filter assembly and it helped a ton. It's just so intermittent and it always seems to take a little time to develop from the first time I fire it up. Im at a loss.Can anybody think of what/how to check when the issue happens?
