REFLECTOR: ALL FIRED UP

[Tom Martino]

So far this has been the most helpful suggestion.  I NEVER knew about
the inner plug!  Once again the Reflector comes through ... because
there are a whole bunch of people smarter than me - including Dave!
Thanks Mr. Dent.

I just noticed your problem with the prop.  You said you removed the
plug from your engine so you can run the C.S. prop.  But did you install
the inner plug.  In order to run the fix pitch you have to remove the
inner plug and install the outer plug.  But if you go back to a constant
speed you have to install the inner plug.  In order to do this you have
to order the right one and place it through the crank pass the governor
transfer tube and tap it in place.  Some times they may have just
drilled a hole through the  inner plug.  If it is the right size you can
tap it and put a plug in it. But it is best to install a new one.  Look
at the engine parts manual and you will see it.  The outer plug is the
same on most of the Lycomings.  The inner plug is different on most
because of the size of the cranks inner diameter.  Make sure to check
this.  The C/S will not cycle without the inner plug installed.

	I'll help break the silence.  I have fired up my IO-540 about 5
times so far.  It runs great and has a Lightspeed Electronic Ignition.
	 
	However, when it comes to cycling the prop ... I never notice a
change in pitch!  (I have an MT 4-blade)
	 
	I know the governor is working and I removed the plug from the
shaft ... 
	 
	Someone said you really have to crank it up in RPM to get a
change in pitch or it'll be too slow to notice.
	 
	Unfortunately, I did not have my tack hooked up for these
initial firings.  The tach is part of my EFIS system which has not yet
been calibrated.  So, I can't really say what RPM I was running.
	 
	It sure felt like enough to get at least some indication!  Any
ideas?
	 
	I am using straight mineral oil on my new engine (if that makes
a difference).
