My F250 started having problems when I put gas in the aux. Tank and I shouldn't have. It started stumbling and sputtering after about 20 miles. I limped on home going 20 mph and knew it was the bad gas in the tank. I cleaned the system up and changed the fuel filter, ran all the bad gas out of the lines, pulled the carb off and cleaned it out inside and out. Still ran like crud. This time I checked the plugs-ended up changing them out with new cap, rotor and coil pickup. Pulled carb off a second time and cleaned again with carb cleaner, inside. (Even pulled jets out and blew all orifices out) Bottom line- still has low vacuum (10-13 in.) And lacks any power. Still acts like its missing for some reason. Tried to narrow down the vacuum leak by spraying carb cleaner around the carb and vacuum lines. Anything I may have missed? Oh, I also put my timing light on it and had 8-10 deg. BTDC timing. Even checked the distributor vacuum advance, it has a slow bleed off; not real bad.
