process of elimination homie, if you smell gas check the fuel lines, obviously if you have a leak the line would be wet, it could also be your carb not being properly adjusted and flooding. as far as the starter goes, you could have some damaged or missing teeth, either on the starter or the flywheel, there's a cover on the rear on the passenger side next to the starter, take it off and inspect. oh, i wouldn't jam it into park anymore, you could fuck up the tranny.
oh and adjust those rockers, it's not going to matter how well you tune it if one of your rockers slips of the pushrod, you're going to have to do it sooner or later.
