carb/jetting+electrical problem

[wodeman]

My son and I have a 92 banshee with FMFs, we just got used carbs off a 99 with 310 mains and 27.5 pilots with a toomey 2into1 intake and a single K&N. Our banshee had stock carbs, NO tors, with an airbox (stock mains, stock pilots 3 turns out, needle on 2nd clip from the top). We put on the newer carbs because the old ones had a bad float, and newer is always better, these were jetted with the K&N etc right? (HA). After I cleaned them out, put them on. Pilots 1.5 turns out, needle on 3 clip from top. Tried running it and it had a BAD bog right off bottom. Runs fine on top. We thought too much needle since it was 1/4 to 3/4 on throttle so we put the needle on 2nd clip. Still had a bog, but it seemed to run better with the choke on, so now I think an air leak somewhere. BUT now is where it gets WEIRD...as my son was pulling it into the garage, it was late evening, the right headlight went out, then we noticed the low beam from the switch were not working, THEN the headlights went out totally. We then thought we would try putting in the stock 25 pilots at 2 turns out for one last run, still had the bog as my son went down the street, good on top end. But when he came back, now the taillight is out WTF!!(?). Any ideas, all I could think first was wiring for the headlights, but why? Can the CDI or the stator be giving me problems causing the carbs not to work i.e ignition timing ? Gonna check the wiring today, I'm TOTALLY lost on where to start! Maybe put on the stock carbs again....HELP (3 weeks til Oregon dunes......Thanks
