<VV> Cam Timing Question

[larry at forman.net]

I don't think so.   I believe it is possible that if the car was jump 
started and the clutch engaged then it might be possible for the cam 
gear to shear.   I was off a tooth and a half off on my Devin C and it 
would barely run at all.   I finally dropped the pan and found the cam 
gear was WAY off.   Except for the time involved, it is a simple 
operation to verify and once done then you know for sure if the cam is 
right or off.
