Timing marks are only on cam covers (B200/230)??
Got new cam in, timed. Had little play with adj. pulley, massive increase low down, over 3K bogs down..tried advancing cam, same??????????????

Marks are on cover of B200.

What timing did the manufacturers recommend?????

4.2mm lift @ TDC

Sorted!! fiddle with cam timing and colder plugs..

Cool.
What plug you end up running?????????

It's a B200 isn't it?
