Rough Idle :(

[FMS88]

Thanks! The truck is completely stock and it just has the stock Mikuni carb. It looks a little rough so I had bought a rebuilt kit I've yet the get thrown on.

The Mikuni is a bear to rebuild; many small parts like springs, plugs, check balls, o-rings, diaphragms, etc. some of which are not included in the rebuild kit. A Weber (if legal) or an aftermarket rebuild are easier options. But if you go for it, separate the three major parts (air horn/float chamber cover, the plastic mixing body and the throttle body) first, then disassemble each separately to manage better all the small parts. Layout the parts on a big table and take lots of pictures to help the reassembly. Also, ignore the exploded diagram included with the kit; it's for a different carb model. You need one for a 32-35 DIDEF-435MT carb (87-89). The FSM has a pretty good diagram and steps to disassemble and reassemble. If you need more info, just specify in a post.
