    1983 ATC185s factory jet size.

    Hello all, I was doing a complete rebuild of my ATC185s' carb and the kit had new jets included.Problem is,the new one for the main jet nozzle has 95 on it;the factory(?!) jet had 98 on it,which is correct? I left the #98 jet in it

    98 is richer, the 95 will lean the motor out a bit, so if its newly rebuilt, then the 98 will do no harm.

    My book says that stock is 95. Run a pulg test to see what one is needed. If it had a 98 in it before then the former owner may have found that it needed it.
