Remove the valve cover and watch the dripping of the oil from the rocker arms
with theengine on. It sh;ould only drip. If you are geting more than just
drops, you need the rocker assembly re-built. This excess is being sucked into
the rear carb via the hose from the T to rear carb. I've been through this as
have many on this list.
