Re: evinrude 15 hp trouble

I would recheck the timing first, if that is off it would make it run bad, especially at idle and since that is the last thing you messed with it would be the first thing I looked at.
As far as the torque ? I am certain that nut needs torqued but to what I don't know.
As a tip, when you post be a little more specific in your title like "timing problem" or "fly wheel torque spec"
It will help get your question answered sooner I think, but if you have an outboard and it has problems you are in the right place.

doing a link n sinc, and proper adjustment of the low speed jet would greatly help your situations. use the segment of this most. link n sinc in your manual.

When you put the flywheel back on are you sure the key did not slip out of place?

Also it it not torqued down and the engine back fire or stumbles it can sheer the key and then be out of time.
