Bro, this was hands down the best carb tuning tutorial I have seen on youtube! I've been looking for a quick to the point yet informative video for my truck with the same exact motor.
Thanks! I appreciate your video, since I own a 1984 Cargo/Utility van that's running a bit rich. Seems to be sucking a lot of gas and fumes are a bit strong!
the air cleaner is easier to install bottom first then the top with the thumb nut, the breathers on the valve cover and has nothing to do with carb adjustments
They're either a throttle return spring so your throttle doesn't go full open while your driving or it is the return spring for a automatic transmission kick down lever
