Re: 1st build and rough running
I thought your rear hub blew? I guess you were able to find a replacement?
Need some more info, what kind of motor, what modifications (if any) have you made, how many miles, what is your fuel/oil ratio (assuming it is a 2 stroke), etc.
My WAG would be you are running rich, both on the needle and main jet, but that info is pulled completely out of me arse... lol
