Here's how to make it easier, pull in the clutch lever and lock it, then turn the flower nut in a few notches then release the lever and test. Repeat till you slide the tire or the engine turns over.
Awesome thanks for the tips very much appreciated. I got it running and it sounds great. It bogs when accelerating and gas smoke but probably it the lubricant i put for the cylinder and piston rings.
Now that it's running do several short 2-3 miles runs letting it cool between rides, check the spark plug color, the white porcelain part should be brown. You probably had a air leak that caused the over heating and piston failure.
