Yeah, but if the valves
are closed and you got a broom handle in the spark plug hole, then it's gunna
push air if it is on the compression stroke. If #1 doesn't push air and #3 does
then I'm 180deg out!!
well you do actually cause you could be 180
degrees out...Its easy with the rocker cover off as you can see where the
valves and rockers are

you don't need to take the rocker cover off to
do what errol suggested....

Mmmmmmmm, OK...
Thanks. I didn't want to take the rocker cover off if I could help
it.
I wonder what the
missers will say when she finds her broom has been shortened... :)
Maybe I could say it was a performance mod... :)
Geordie, Take the plugs out
of the engine and put a clean piece of wooden rod (old broom handle cut
off etc,) on top of the plug hole and press down As you turn the
engine over if on compression stroke you will hear compressed air
escaping between the dowel and the plug seat. Cheers Feral

Sorry if I appear dumb, but what sort of
engine are you using this home-made job on? I am interested in
finding out more from you about this, I have just bought a microtech
EMS and am going to hook it up to my SR20t tonight. It appears to be
a very simple system as far as wiring, but the software appears
quite detailed..
Another thing is that when I got the engine
the Crank Angle Sensor was removed. I believe that to install it is
similar to a Dizzy, you put the motor on TDC#1, install the dizzy/CAS
with TDC1 mark or rotor posi lined up with the sensor/#1 pickup, and
then offset it by the timing angle, ie 10deg or 8 deg or 15deg
whatever is required?
Is that the correct method?
Also, if
that is so, then how do I know I've got TDC on #1 and not #3? Do
I have to pull the rocker cover off and check which one has both sets
of valves closed?
If anybody on the list knows any of these
answers I'd appreciate it... Maybe Pete
knows?

Just a little
update on the home made engine management system for
anyone interested.
The ignition part of the system works now –
I was up most of the night with the system plugged into the back of
my computer throwing sparks all over the joint. Great stuff –
really wakes you up ! All that’s left now is to mount the crank
angle sensor and it all should work. It’s actually quite
amazing how much stronger the spark is compared to the old dizzy
setup.
The Fuel injection system is coming along as well – I
obtained some old Webers which I’m going to use as throttle bodies.
All I need now is to construct an EFI manifold which has inch
and a half exit ports to mate with my
head.
Jeff
