    125 is the start point for the main jet on a 172, then run higher or lower depending on plug chops - if its the 25G carb you can only keep the standard 50/100 idle jet, though if running a 24E carb I'd bump the idle up to a 55/100 and run a drilled filter or without one.


    ... now what do I win? Laughing
