sounds like air mixture screws should be about 2.5-3 out your rear shouldn't be out that much make sure you do this when the engine is warm it will change from cold to warm its a pain to do this without the special tool if you can get your hands on one it will make your time easier

Anything past 3 out doesn't do any good. Probably need new pilots. I've got mine about 1.25 turns out.
