Can anyone help me with removing a flywheel?

[Calebc]

I’ve got a Johnson 25R70E and it’s not getting spark. I decided to remove the flywheel and check the points etc. but I cannot get the flywheel off. I’ve got a puller and tightened it as much as I can as well as used PB blaster, an impact, ball peen hammer, and even a blow torch. It’s not budging. Is there something I maybe missed? A secret nut or bolt I don’t know about? Any help would be greatly appreciated!

soak soak soak .
if heat does not work try freezing... a keyboard dust spray can.....can cool things down fast A can from a dollar store will shoot pure spray held upside down and should help... spray the bolt only then heat up the FW fast to create a shock....try puller while heating the FW surroundings .

or a teflon spray may have better capillary effect to soak the threads .

Sharp blows to the puller its self while under tension sometimes helps as well.

Steering wheel puller, impact or hand wrench very tight. One big smack gets mine Everytime. Big hammer.

Show picture of your puller.

Hammering on a Flywheel/Crankshaft is NEVER Good Idea.
Thermal Shock might work, though heating the Flywheel can create other problems, there are Magnets in there, and their Positioning can be disturbed if the Flywheel warms up, resulting in Contact with the C

I would leave it under Tension, and check it every few Hours to see if it can be tightened some more

I wonder if someone had it off in the Past, and Over Torqued the Nut when putting it back together?.. That would also ruin the Flywheel
