So this is really my first mechanical project I have attempted by myself. It ran for a while but I have come to realize the spark plug is crap. My crankcase was leaking, I tightened the bolts on that run through the cylinder head and the case cracked right under the head. I am pretty sure it is called the crankcase anyways I will put up pictures in my next post. What I was thinking about doing is just ordering a new crankshaft and putting it on, getting a new spark plug & cable, & getting a new carb but I have no clue where to start any help would be appreciated. I have the 2012 Grubee Skyhawk GT5 66cc with the new carb everyone hates.
