is that normal?

Absolutely not normal.

What are you testing it with because a motor runs about 140 which means 10 times hotter is 1400 deg. Get a temp gun flywheels can get hot how much hotter you need to be more specific. I have a 1986 70 hp evinrude after i run it if i lay a forearm across the flywheel it will burn me.

No not normal.
Sounds like it's rubbing somewhere.
Look up under and see if the magnets loose or rubbing.
The magnets a long thin strip that is glued inside the flywheel.
I never tried touching it after it's ran but if it's spinning it shouldn't get hot as the air should cool it.

i looked everywhere for the rubbing i cant really see anything rubbing.

i did tighten the flywheel nut with my impact to make sure it does not get loose due to when i followed the specs 90ft pound it sheared my key.

could that be the issue?

or can it be a ground goind to the stator and creating a heat due to both shorting? im guessing that could not be because that should short instantly and also not be able to work

No Title

sorry about previous post did find after what i think is the colprit.

one of these plates of the flywheel is a little biiger and i could see it made a small grouve in the trigger..

should i just grind the excess off??

thanks

i removed the weaken ring on the inside. i filled down the sharp ends. ran the engine for awhile did not really get to hot just warm. did touch the winding around the stator was a little warm also, unless anyone objects this is solved.

thanks

Warm is normal. And yes, the rubbing made the flywheel hotter than normal. I believe you are in the safe zone now.
