I think you can be successful with a conversion.... but at the cost of a trip to the racetrack these days.. I think either purchasing a carburetor or having it converted is the way to go.. I have had dealings with Mark sullens and pro systems and both have been very good... they both have completely different ideas which both returned great results.. I think five or six outings to the track. Figuring out the carburetor... You will have spent more money and more wear and tear then it's worth
