Hi Max, not sure what you mean by different carb’s, have they been replaced at some stage?
As regards the fuel mixture screw all I can tell you what mine are set at (factory setting) Front 2 1/4 turns out and rear 2 1/2 turns out. They do recommend that you don’t alter the factory settings on these but if yours has been tampered with you could try the settings above.
Marcel is the best one to ask as regards the main jets, he supplied me with larger main jets front and rear (rear been larger than front) I did not change the pilot jets, my original main jets were 8.25 front and year. The theory behind having a larger main jet on the rear carb is to aid cooling of the rear cylinder, but as I said Marcel is the guru on these matters.
The two screws on the the float bowls is just a drainage screw so should be screwed closed, not too tight.
Alan.
