I purchased a carburetor for a Stihl Blower BG-85 which was shipped priority mail but when I opened the box and checked it out I noticed one of the primer bracket screws loose and contaminated gas in the primer bulb further inspection showed that the regulator diaphragm was hard and rigid and the main jet stopped up which only allowed the blower to idle. This carb is not repairable!, I'm returning it as received . The nice lady I talked to said to return it for full refund. Customer service was good but the carburetor bad. Quick service bad part.
