I finally got the drive belt in place!
Then I had to straighten a bent bracket and add two washers for a pulley to get lined up. Was able to get the motor running, I went for a drive and everything looks, feels and smells like it’s all good!
NOW I’m back to the motor won’t start!
Has my engine jumped out of time?
The motor starts to spin then I guess the spark plug fires, I hear a loud pop and the engine goes backwards. I hit the key and it will be spinning one way, but it’s like when the compression gets into the cylinder the engine turn slowly till it gets past that and then it’ll spin kind of freely till it hits compression again and it will slowly go past that. If the gas fires during compression it moves engine backwards!
Where do I start fixing this problem!

It helps to have the product label information off of the machine, so we know what engine you have and how to better help you.
Rider engines don't just jump timing or shear a flywheel key.
When it comes to push mowers, they will shear a flywheel key when the blade strikes a had object and suddenly stops the engine.
From your brief description it sounds like this engine needs the valves adjusted properly. When the valve lash is too wide, the compression release doesn't work efficiently and the engine fights higher than normal compression. This will cause a stop in cranking and reverse rotation issues.
