Chain break in

Ok so i put my mini bike together to screw around on it before i go to get the frame painted. So when i first rode it, i rode for 2 mins and the chain was so loose that it wouldnt stay on. So i tightened it, and repeated this process about 8 times, only riding it for 2 or 3 minutes each time. (by tightening it i mean moving the engine forward. So the chain just keeps loosening up, i don't know how it does after 8 times.

If i had to guess... sprocket/axle gear is outta round (isn't traveling in a circle)... or possible that your producing enough torque to slip/drag the engine back... or could be both...?

Well atm i only had 3 bolts that were holding the engine so that most likely it, the torque of the 212 probably pulled it back. I feel stupid for not realizing that Lol, i could get away with 3 bolts when i was missing one for the 79cc engine but not the 212 lol, too much power.
