I recently replaced the stator, trigger assembly and flywheel on my 1986 Mercury 75HP. It's a project motor that had some mysterious and intermittent no-spark occurrances. So I threw as many ignition parts at it as I had on hand.
Motor ran smoothly before I swapped the parts, with a nice steady idle. But since the swap it runs like crap. Super-high idle that I cannot bring down, and it's running extremely lean. I fear I may have re-installed the flywheel incorrectly. I admit not paying attention to the "compass" position of the flywheel when I pulled the old one off and put the new one one. I just set it back down on the splines, thinking it didn't matter where the magnets are.
I now know that the position matters for timing reasons, but "IF" the flywheel is off by a little or a lot, what would the effect on the motor be?
Feel free to call me out for being naive about the flywheel. Deserve it totally.
