Hi All,
I spent last week in Michigan where I worked alongside a car guy. We talked about valve lash and how it’s set. The nuance about setting lash escaped me. I was encouraged to set the base so the rocker just made contact with the pushrod and to not focus on the spinning sensation of the pushrod as the indicator. I used this approach as I rotated the motor one cylinder at a time, rolling the motor four complete rotations. I used the rotor cap as a visual and the increase in resistance to approximate cylinder position. I used the rocker arm movement to find the zero play point. Once satisfied with the zero lash, I set all valves by a 270 degree additional turn on each nut.
I fired it up tonight and it is purring with just a slight idle fluctuation. I haven’t even set the timing. I may have to pull the manifold apart again because the front valve cover may be leaking. But I have that process down to about an hour now. It sounds so cool.
