200 HP 2 Stroke Squealing

[Ddingman]

Hoping someone can help me here. Took my boat out this weekend and cranked up the motor and it was making a loud squeking noise, seemed like it was near the flywheel. Got it off the water and cranked it up with the hose and was still squeking. Hit the top of the flywheel with some WD40 cranked it back up, ran for about 5 seconds then died. Then trying to crank it up and it cranks, cranks, cranks, then backfires. Will not start now, just trys to crank then backfires. I'm stumped. Hope someone has seen this issue.

what did you think WD40 would do for the flywheel?
if something is rubbing on the flywheel, you need to find out what it is.

if there spark to the plugs?

Yes, checked the plugs. They are all good.
