Test the compression using a compression tester.
My guess a valve is stuck closed.
A compression test will show this.

I'm pretty sure that has a stator and oil in it is normal.

1. Place the transmission in first gear

2. Rotate the lockout switch forward to unlock reverse gear

3. Shift into reverse gear

When you shift back out of reverse gear, the lockout switch will reengage automatically to prevent accidental shifting into reverse

Yes you do or just go to the store that you bought it or return it to the person that you bought it from. Thanks for my option

First be sure to check oil level if you haven't. Many have a low level shut off switch. If the level of oil gets below a certain point it can shut off. Just a thought.

Maybe, vapor lock. Gas cap is not venting.

Thats not much info but ck the fuel supply and or coil.

have you checked the valve clearances?

having same prob with my preditor 500 any advice
