Needle Valve
by Stanley from Sherwood, Oregon on April 16, 2013

Most diagrams didn't show the spring, and my out board would run but not like I thought it should. For my crab it needed the spring now it works better.

This is not the problem of Iboats but maybe the part indentification for the carb was wrong. The part received was not the right part.
