    wmb-4 carburetor question

    https://ibb.co/ckM5g8C It fits pretty nicely in that hole. Could it just be a plug for the body? the channel goes towards the fuel pump but I removed the pump cover and the hole doesn't connect. Am I missing something or could this be its home?

    wmb-4 carburetor question

    Hello, as the titles states I have a WMB-4 carburetor off of a 7.5hp outboard. I was taking apart the carb to clean it and I think I heard something drop. I picked up a pin about 5/16" long. I have no idea where this might go or if it even is a part of my carburetor. I didn't see any obvious...

    1964 Merc 500

    Hello! I am the proud new owner of the family's old boat. The boat has a 1964 Merc 500 on it and I would like to know if it is worth restoring it.
