Idle RPMs don't seem right!

[raveng60]

Just wondering what's a good rpm idle for a force <br />1989 50hp... its 2 cylinder 2 cycled engine with a 50:1 fuel mix.<br />right now its idling at around 1500-2000 but that seems kind of high. if i go with lower rpms it seems not to start as easily and die at idle.

Idle should be 700-800, when engine is in water - in forward gear.<br /><br />Have you checked the compression on your motor?<br />If not, time to do it.<br /><br />Also check for a hot spark on both plugs.

And a decarb would be good idea after the compression check. then check it again after you've done the decarb.

so 1200-1500 rpms would be about right in neutral and out of the water???

In my opinion, still too high.<br />I would think 900 for being in neutral, and maybe 1100 for neutral and out of water.<br /><br />Been a real long time since I ran a motor on muffs instead of in a tank.
