goodo jack and yup , it needs the engine fan to work the G3 gove' flag . blow it out then relaxxxxxxx revs up revs down . might be possible though , never really thought about it before .
drill out the main jet for more fuel .... but thats a whole nother story !!!
if the inlet manifold wasnt so RARE you could put an oftake in it but you only have one chance to get it done right .
i know a lot dont and never will like G4 and LM's but a hard thing too do is change from one to the other
