its raining in new york and i wanted to go for a ride in my truck but the wipers no longer work. i know they worked a few weeks ago before i sent the carb out for a rebuild. the truck runs perfectly but when i turn the knob for the wipers all i get is a hissing sound and a slight increase in idle. how do i trouble shoot this? thank you
