Almost sounds like the cam is <i>way</i> out of phase (I think even
unlapped valves would seal better than that). The 'count 13 links'
cam install 'system' is wonky at best and confusing. Fortunately, I
don't think the Austin is an interference engine.<br>

Hello Patrick,</p>
<p><br>
</p>
<p>Between 5 and 10lbs can barely be called a compression so
something serious is amiss. It should be well above 5bar for any
engine. Depending on C-R and wear. Even with a slightly burned
or not lapped in valve.<br>
</p>
<p>If it is not the clearances it really looks like a head off job
to investigate and sort the valves. Luckily not too big a job on
the A-H.</p>
<br>
<p>Cheers,<br>
Kees</p>

<p>Did you check the firing order, camshaft timing, valve
clearances? Does the distributor shaft turn when the engine
is turning over?<span
style="mso-ligatures:none;mso-fareast-language:EN-AU"><o:p></o:p></span></p>
<p>Check the bypass wiring of the ballast resistor. Check the
correct wiring of the coil, you would not be te first to
have the polarity wrong.<o:p></o:p></p>
<p>The compression on a freshly rebuild engine is lower than
on an engine that has been properly run in. It also depends
on the tolerances and surface finishes used in the rebuild.
Assuming that it is a proper rebuild the compression should
not be an issue here. Whatever the compression the engine
should start.<o:p></o:p></p>
<p>Timing and fuel cannot be spot on as the engine is not
running and fine tuning of mixture and ignition should be
made on a running engine. It is however not an issue either
as you set ignition initially statically as you do with the
adjustment of the carbs and it should at least run on that.<o:p></o:p></p>
<p>Are the spark plugs wet or dry after churning? Try spraying
some easy start fluid (mainly Aether) into the throat of the
carbs during turning over and see if you get some life. If
so it is a fuel issue.<o:p></o:p></p>
<p>Good luck.<o:p></o:p></p>
