Goeff---It's interesting that you find the bluntness between #2 & 5
intake ports. The port on my '73 looks as if #4 doesn't get its fair
share. This is somewhat confirmed by #4 sparkplug always being the
cleanest of all, thru the many miles this engine has gone. Compression
is always equal to the others, so I don't know what to make of this. If
you do something that seems to make a difference, please let me know.
Does anyone else consistantly have a spark plug that shows up cleaner
than the rest?
