It turned out after doing everything everyone told me to do, i finally figured it out when i was driving i reached down and turned fuel petcock to the prim position and the bike stopped studdering and started running good. i went home and replaced the right petcock with a spare i had and the bike has been running great ever since, good luck, morgzilla.

Hi Morgan,
that post just made my day.
Reminds me of my apprentice days riding to work on my trusty Cyclemaster moped.
Pedal to start, drop clutch, engine starts, runs 100 yards, quits.
Pedal another 100 yards, drop clutch, engine starts, runs another 100 yards, quits.
And so on until in sight of the factory gates.
Reach down, turn gas tap all the way on, no more problem.
