Lowering the needle will lean it and rasing the needle will make it richer
But you said the plug is wet and it cuts out if it aint the cdi black box it must be fuel related.
I don't have the ohm reading on the cdi maybe we will get someone to jump in that has these reading handy. If not I could check mine and get back to you.
Don't give up.
