My truck's blowin black smoke out of the exhaust when i start it and for awhile until it warms up. Im thinking it could be my carb, where could i find some information on adjusting it to run nice?
It idles rough aroud 500 rpm when its warmed up.
Also, what kind of fuel mileage do these trucks usually get? because my 87 b2200's getting only 200 kms to a tank and that seems a little low.

Any information helps, thank you.

yeah black is fuel...I would clean your carb with spray carb cleaner first, check your air filter...and you are getting really crappy milage you should get 450-500kms
