1997formula583 is an unknown quantity at this point
Default carb tunning for bored over engine?

at low end I think it is rich and pretty close to good at top. I think the carbs are from a 670 mxz (40mm?). it had 60's for the polite I have already went down to a 50 and it is still rich I think should I go down another size or keep playing with the idle air screw.(does that even change anything with the polite?). what are the symptoms for rich and lean?. also if anyone has an idea for what jet should be used its a formula 583 but it has been bored over .030, if you have any ideas I really needs help with it right now
