gets a good lube job. I have nice duals on my 39 convertible. If I didn't put
MMO in the last tank of fuel when I start it you can hear the sound of the
pipes. They boom, boom, bip, boom, boom, bip. The bip being a miss from
a sticky valve. I then drizzle a little down the carb while running, put a pint
in the tank drive 20 or 30 miles, come back and it just sits there with a
steady boom, boom, boom. If any of you ever talk to Skip or you can call
him he has heard it before and after MMO a number of times. I can also
detect a stuck valve which you may feel a little miss at 40 or so MPH this
is definite when in high gear slow down to about 8 MPH and slowly step on
the gas and you get a little bucking. After MMO it pulls out with no bucking.
