more problems

[frantic84]

so I'm starting to get really stressed here (Vegas) 300cc Mechanics are hard to come by and when you can find one boy do they charge!

anyway,
so the pipe leading from my engine to my muffler cracked for the 2nd time (this was a brand new replacement part too), my carb is bleeding gasoline (most likely a stuck needle), and my cylinder base is leaking oil (need new gaskets), this is my get to work vehicle! 300cc icebear magnum 2011,

I got it used for $2000 and have put at least 150 into it so far and have a lot more to go!

any Ideas, can/should I part it out/sell it? who would buy it in this condition? what could i get for it? and if I do sell/part it out, what should I replace it with?
