I have a 1985 Sylvan V171 with 200 murcruiser MGM 305 with thunderbolt ignition ( serial # S389755 ) would not go over 2000 RPM
I changed spark plugs rotor and cap and coil ,wires ohm good Now it runs fine
The disrtibutor cap has a port on side should it be capped or is there a hose attached to it and if so where does it go
also the ignition sensor is rusty can i clean it or should it be replaced
