Also worth checking if the engine is flooded. Too much fuel getting
to the cylinders will cause a non-start condition. BTDT story: With
SU carbs (Herald 948cc motor, pair of SU H2), it was as easy to fix as
lifting the pistons (basically no depression on the fuel jets, so no
fuel drawn in) until the cylinders were cleared and it fired. Then
released the pistons and it was running. Dunno if it's as easy to do
that with Strombergs (I assume a 71 TR6 has Strombergs.) And with
spark just about anywhere between 5 or 6 before to 5 or 6 after, the
timing should be close enough to start. Not optimum for economy,
emissions, performance or any of those good things, but it should
start. 12 before is too far advanced (IMO) for a first attempt at
startup on a fresh rebuild. I'd retard it to around TDC, get it
running, then start the fine tuning.

AMEN!
