Hello all - new member with a new to me boat. I bought a 1964 Starcraft with a 1964 Johnson 28HP RX-12M that is electric start. after first starting the engine it ran like crap. That is when I discovered fuel leaking out of one of the spark plug holes. At some point it had a heli-coil done that came loose (I could actually feel play between the plug and head). So I bought a new OEM cylinder head and gasket - now I just need to know how to install it (proper torque, proper gasket sealant etc.). Any help from the pro's is most appreciated? by the way I was amazed I could still get a brand new cylinder head at a reasonable price - pretty cool.
