Oops ... the lift isn't checked at TDC, but at some point on the intake stroke.
Don't know the exact procedure, offhand.

Sounds like valve timing is off. You'll need to check the lift of the #1 intake
valve at TDC to confirm, one way or another.

After having problems with the poor running of my BN4, I put an electronic
ignition in the distributer (which was also overhauled) and rebuilt the carbs
using a carb kit. However, I still can't seem to get any power.
I am pretty certain that the timing is right (having checked it with a timing
gun), all the electric connections (plugs, cables, etc.) seem to be sound and
I cannot identify any specific problems with the carbs (ie leaks around the
inlet manifold, etc.).
So I think the trouble is with the setting of the carbs, but I have been up
and down the adjustment nuts (rich to lean and back again) without any
success.
The symptoms are ... a smooth idle, smooth but very sluggish pick-up on
acceleration accompanied by a loud machine-gun type rat-ta-tat-tat!
Any ideas?
Thanks
