Need some help guys...I am working on a 86 Johnson GT 200
1st off this thing is running champion plugs # ql77jc4. Are these the best for this motor or is there a better plug or heat range? WHAT SHOULD I SET THE GAP AT? It sits on the back of a bass boat.
2nd does anybody know how much compression is normal at cranking? It has about 12.4 volts.
3rd this is turning a Raker s/s 467 prop, what is the pitch and so forth. Is there a place I can go and find out more on this prop.
4th there is a manual jack plate....what is a optimum height for this motor? How far can he push this thing without scaring the guys or blowing the prop off?
5th should I be running a different prop 4 or 5 blade?
6th oil injector burns real fat at start normal for the older system or not?
Thanks for any help
