T.D.C may not be marked in the correct position on the pulley
the dizzy drive may be in 180 degrees out (installed opposite way), may be it is no. 3 that should be firing.
are the two rockers on number three cylinder both "rocking" as you turn the engine back and forth past what you think is TDC?

B4 u rip things out etc, try rotating the eng by hand or getting someone to do it while you watch what the rockers r doing on no. 1 pot. The cycle is
of course (if u'll excuse the double entendre) "suck, press, bang, blow" with the spark occurring at the press stage when both valves r shut. That
will expose any errors in TDC marks etc.

Well got it sorted.Seems i forgot to allow for the swivel feet adjusters that are fitted to the new rockers.As i screwed the rocker assembly down it
was holding inlet and xhaust open!So I shimmed the rocker arms up and checked for valve bind. I found three bent pushrods!I did notice the pushrods
are very close to, if not touching, the inside of the pushrod tubes.Is this normal?
Thanks for all the advice.
