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 Errol

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
