Okay so i finally got around to seeing what jets this thing has in it. Not sure if im gonna get the names correct but here it goes.
At the bottom of the bowl the primary fuel jet is 140, the secondary fuel jet is 155. On top of the carb/bowl (air jets??) The primary air jet is 170 and the secondary air jet is 160. Do those sizes sound good for a 2.0?

Background, truck runs rich around 16mpgs. Choke has been set, idle mixture adjusted, idle adjusted, float has been adjusted.
