If you go to www.vintagenorton.com they have a copy of the owners manual for the WD 16H that shows and describes how to set up the valve timing. That should help.

thanks bobh it was helpful

spoke to mike pemberton at pushrod ,great guy who gave me some pointers ,got inlet @ 30 BTDC and exhaust fully closed @ 28 decrees ATDC using a degree wheel

mike also told me on the pre 1947 16h with only the exhaust cam driven by the pinion, the best setting are 30 inlet and 25 exhaust ,i just could not quite achieve that but i got close

also used the 3 slot pinion ,one slot = 1/3 of tooth to get as near as i can ,i will drop the engine back today and see if i am correct

if anybody else experiences the same problem please ask and i will post how i did it ,the hard part i found was getting me head around it ,the actual timing part isn't as hard as it seems
thanks again
