I feel honoured to have commented on such a rare beast!  I am confident =
it is valve timing and all will become apparent on checking.

Thank you to everyone who responded. Much appreciated.

We will start inspecting next weekend.

Just a reminder that the 100 BN3/1 is Warwick built Austin-Healey and is =
not a four-cylinder car and is fitted with an early C-series smooth =
crankcase six-cylinder engine.

When it=E2=80=99s sorted, I will send a message to the list.

Upon assembly of a 100 engine, if you replaced the cam, cam gears =
etc.with new parts, the indicated punch mark for the 100 is not correct. =
IT IS ONLY CORRECT FOR A 6-CYLINDER engine. You cannot use the mark and =
must follow the diagram in the manual and add a mark after you locate =
top center to the cam angles. (photo) They do not sell a cam sprocket =
for the four cylinder engine and you must correct the one supplied or =
your valve timing would be way off as you found with no compression. You =
should have 120-150 lbs on each cylinder-equally-even with an new engine =
that does not have the rings seated. After correcting the cam timing be =
sure that the distributor is not 180 degrees out. Good luck, Hank

Is it possible to install the cam backwards?  It is on some cars.

Hello

=20

No amount of churning over with a new battery will induce the =

the road failed to instill any life into the engine.

=20

Everything is spot on =E2=80=93 timing, spark and fuel.

=20

Anyone have an idea as to what the compression be on a rebuilt engine =
should be?

=20

Many thanks
