on an 85 110 which way should the au=ir mixture screw be turn and how much

 

If I remeber right it is all the way in until lightly seated and backed out 1 1/4 turns. That should be close anyway. As far as adjustment goes just remeber when you screw it in it makes it richer and when you screw it out it learns it out.

 

I believe on that carb, its a mixture screw, in which case, turning it out is richer, and in is leaner.

 

Pretty sure its an air screw.
