    1990 Force L-Drive 90hp -- Can't get it to idle -- losing my mind :D

    Yeah this was my feeling; I'll see if I can find a new diaphragm.

    1990 Force L-Drive 90hp -- Can't get it to idle -- losing my mind :D

    Thanks for the detailed write up! I think I still may be out on my timing, what I thought was 28 might be 32, so I need to keep loosening it.

    1990 Force L-Drive 90hp -- Can't get it to idle -- losing my mind :D

    So I re-examined the manual which states: - Put the throttle IN GEAR at Wide Open Throttle - Set the timing to 32 degrees You can also get a digital timing gun that advances/retards the timing on the gun, but I just happen to have a shorted neutral switch anyway, so I was able to pull the...

    1990 Force L-Drive 90hp -- Can't get it to idle -- losing my mind :D

    It appears that my timing is probably too far advanced, will adjust tomorrow: https://www.comeanddriveit.com/engine/detonation-and-knock#:~:text=Too%20Much%20Ignition%20Timing%20Advance&text=This%20causes%20long%20burn%20times,the%20remaining%20mixture%20to%20detonate.

I posted this on a FB group and they're like "ROD KNOCK" don't run it. So I'm thinking my timing could be off by 2 degrees, because I just double checked...

    1990 Force L-Drive 90hp -- Can't get it to idle -- losing my mind :D

    Someone mentioned it could be bad reeds, I'm not yet educated on that... Thoughts? The leak would be occurring on the carb side, right? One of the idle screws is lose, I'm not using the right spring, but if I tighten it all the way down it does its job and will kill the engine. So its running...

    1990 Force L-Drive 90hp -- Can't get it to idle -- losing my mind :D

    Hey all, 1990 Force L-Drive 90hp 1) My buddy got it running at idle and it sounded really nice -- but would sputter out and die when going into gear on the lake. On the muffs the prop spun just fine. I did play with the carb idle screws and actually got to do a few circles on the lake, but she...
