hey guys i have a 1990 2wd pickup with the 22r carb motor and a 4 speed manual tranny, is starts and idles just fine but when i went to drive it today it just wouldn't hit mid to high rpms. if its in neutral and i roll on the throttle real slow it revs fine and doesn't skip a beat but if i hit it to hard from an idle or under power it cuts out. Maybe not getting fuel? i'm not really sure where to start, i'm thinking it may be to fuel filter or something in the carb, any ideas?
