yes the spark plug makers also tell spark torque most show 15ft llbs, max. on new plugs i can acutally feel the hollow spark washers collapse just as you near 15ft/lbs.
if spark timing looks ok maybe the cam is timed right. compression is the only sure fire way to know it is.
the compression is a bench mark at sealevel, and very repeatable.
"My 91' 8 valve, pulls 155 psi. (dead cold at 72F) Suzuki minimum spec for hot coolant is 170 PSI " most do that warm to hot. easy.... g16A
the reading as function of altitude and compression ratio and not displacement. (sure cam profiles but all are same here)
this check at wOT shows the Previous owner did the cam time correctly
then set spark time next,
if both are good then work spark or fueling.
you have vacuum advance there?
