It is done...(well almost)

[rocco16v at netzero.net (L F)]

IF the timing was the problem, it would seem that would be the case. 
A broken belt however means the cam(s) just STOP...almost instantly.
(I can't remember what caused this problem in the first place)

  It didn't dawn on me till after I sent the mail. But...
  If the timing were out enough for #4 to hit, how come 1-2 & 3 never did? 
  Thtas what we were trying to work out.

  In a running engine, the occurrance of the piston rise and valves opening 
  happens in milliseconds. After #4 crashed, the #2 should have been smacked a 
  few milliseconds later. (1-3-4-2 firing order). See what I mean?
