I recently did one on my UK MkIII (1296 cc) and got:
#1 - 163
#2 - 161
#3 - 173
#4 - 163
Throttle open, dist. disconnected at coil. Any ideas why #3 should be higher?
#2 oils its plug
pretty efficiently but looks OK from this, yes? Are these the right sort of
number, they seem
quite a lot higher than Ray's figures?
Cheers,
Martin.
