How do i adjust the carb on a McCulloch super airstream 4 gas blower vac? How many times do i turn out the fast and the slow throttle screws once they are in all the way?
There is no set adjustment on any blower or chain saw. If it were that simple there would be no need for adjustments. The problem is that most equipment manufactured in the past 10 years can not be adjusted by the user. Carburetors are now equipped with either adjustment limiters which limit the adjustment to less than half a turn or with adjustment screws that require a special tool to make the
adjustment. More than likely you will have to take it to an authorized dealer for those adjustments.
If you do have an adjustable carburetor, then gently close both needles and open each on 1 full turn. This should allow the engine to start and the final adjustments can be made at that point. If it still will not start then open each needle 1/8 to 1/4 turn and try again. If this still does not work then most likely your carburetor needs a good cleaning and a rebuild kit.
