I'm now the proud owner of a 1978 Merc900/90. Bought carburetor rebuild kits.
Plugs in kit will not fit into recess, too big, so if someone would be so kind and let me know what is the measurement of the plug in an 1978 Merc 900/90 serial number 5033721 WMK 23 carburetor it would be very much appreciated. And where to purchase same.
Please don't ask why I removed it
