$4.95!!!!???? the local mercury dealer could not come off of one of these things unless I bought a new carb for $350! Why mercury protects this screw with an armored aluminum shield is beyond me, but it was the key to my carb being tuned correctly. Mike - thanks for the youtube video, showing how to clean the carb, and most of all thank you for carrying these oddball parts the dealer charges and arm and a leg for.
