carb help-mixture screw settings??

[awesomeame]

rebuilt my carbs, first time since i bought the sled.(used) found some interesting things:

==>the mixture screws were all at different spots. one cyl at 1.25 turns out, one at 3.75 turns out, one at 0.75 turns out. The manual calls for 2 turns out. so what the heck??? i put it back the way it was, but shouldn't i put it to factory specs?

==>the clutch side cylinder, i can touch and hold the exhaust pipe, while the other two i can only touch for a second. i noticed there's an exhaust leak at the pipe to the muffler, when i held that as tight as i could the pipe got hotter, but not sh1t hot like the other two. there's spark, compression and the plug is wet a bit. it obviously burning something, but the burn isn't the same as the other cylinders.

which bring us back to the mixture screws mentioned before. should they all be the same, or wtf? i think that may be part of the prob here
