Tappet settings for a Williams PW3 Cam

Hobbes · Jun 25, 2014

Hi, can anyone tell me what the valve clearances should be for normal road use with a PW3 cam, I've seen 0.011" and 0.013" mentioned on some forums
Thanks

Why trust those other forums :wink:

And why not read the spec sheet supplied with it? Or contact the supplier?

I plan to start Peel off conservative as manual suggests then creep down on lash checked fully heated till quiets as good as can with some reserves left of course. Done V8's while running till best lack of sound effects gotten on each lifter. Not possible on our moving rocker end adjusters darn it.

In the Norton engine rebuild video, which Mick Hemmings does, the pw3 has 11 thou valve clearance.(As I remember)
