My apologies.
I forgot to say thanks to everyone who took the trouble to write with their
advice.

Subject: Re: [Healeys] Strange Timing Setting
I will assume everything is correctly installed & the #1 piston is at TDC on
the compression stroke & not TDC on the exhaust stroke. Also, I assume your
engine includes the angle drive pedestal for the mechanical Tach drive. Is it
not possible to re-install the distributor drive gear such that the rotor is
pointing at the desired location for #1 plug wire? I.E. "Re'clock" the
distributor +/- 120 degrees CW? I understand that this will result in the
distributor drive slot not being at "20 to 2", but do you care?
Your description stated "Number 1 piston is top dead centre and the rocker gear
is rocking." Is that not a description indicating that the #1 piston is on the
exhaust stroke?

Perhaps someone has come across this before.
About to start the engine in the BN3 after a complete rebuild. The engine is a
very early C-series six-cylinder and the rebuild included new bearings
throughout, pistons, sleeves, valves, vernier adjustable timing chain etc.
When setting the timing all the settings were done by the book. Tappets at 12
thou, the pointer on the timing chain cover is pointing to the notch in the
harmonic balancer, the gear shaft drive from the oil pump/camshaft is at 20 to
2 and the offset distributor drive is correct. Number 1 piston is top dead
centre and the rocker gear is rocking.
Imaging please looking down at the open distributor and it?s a clock face.
According to the book, the rotor button arm should be at 2 o?clock or firing No
1 spark plug.
However the rotor button is a 10 o?clock.
So it?s not 180 degrees out, but 120 degrees.
Of course you could get around it by changing the spark plug leads, but the
result looks untidy. An alternative is to rotate the geared shaft drive
clockwise by 120 degrees.
Any suggestions?
Thanks
