Jasen, I would try obvious things, like is the gas tank venting. Does your petcock flow enough gas? Is your float set right, damaged needle seat/valve/float? Yours has an FCR as well, I think you said. Is the thing set up right? Will it start choked?
Look at the coil, is it connected right? Is your spark plug good? Is your plug wire/cap, etc. undamaged? Any water in spark plug hole? Is the drain from the plug hole clean? If you bring it by, I am sure we can heal it, but I am way to lazy to come up there, sir.
I cannot think of anything else, you do have an E, so make sure your CDI box is a 72?
Check on TT at Eriks post to see which you should have.
I am now officially out of guesses. Maybe I helped, maybe not, but at least I occupied you for a bit.
