I have a 1984 Johnson 15 I just revived after sitting for 5 years. I have read the SSCHAPTERPSA articles and had a few questions for the experts. I have rebuilt the carb, water pump and fuel pump. New plugs and all new fuel lines. Engine starts on 2-3 pulls but turns over a little slow on the electric starter. 1) How far should engine move from front to back? Mine is moving almost 2 inches. Are the upper thrust mounts shot? 2) Will engine performance improve after running in the water compared to running on the hose? Should I limit RPM's until I have an hour or two on it or should I run it like I stole it. 3) Last question, Have any of you ever seen the plastic intake fitting or black top of the fuel pump with a pinhole in it. Mine is leaking from around the inlet tube when I pump the fuel bulb. I took the cable tie off and put a hose clamp on but it appears fuel is coming out from around this area. I took the fuel line off the carb and fuel pumps through when bulb is pumped.
