"Further more after I have the chain fixed how am I to get it around the gear of the motor when its not enough room to wrap it around after removing the cap."
If I'm reading your question right, you need to remove the cover plate and use a socket to advance the engine chain gear (if you loosen the spark plug first it is easier to move). Turn the gear as you feed in the chain and then you can pull it by hand. Engine kits come with a socket for doing this. Hope this helps. Welcome to the forum.
Someday when I grow up I will probably lose interest in toys with wheels, but until then...
