I added a couple of parts to seal the throttle
push pull control rod with a small Teflon encapsulated
silicon O-ring..

BTW we are dropping all people on AOL in one week. We are still
getting too many bounces.

Paul,

Yup.   That's what I was thinking. Looks great.

Doug,
I thought you said you didn't like 'O' rings here! I was starting to wonder
why - were you alluding to the possibility of too much resistance or
something?
George ( down under)

George,

No you are correct.  I don't a O-ring in that application.  It will
eventually wear unevenly, ingest grit and not seal as well as other seals
designed specifically for that purpose  but it is a mute point now because
for the prototype it should work fine.  BTW I liked your design because it
eliminates the possibility of air leakage "BETWEEN" the two ports which
could be a factor in the timing.

So... George I am starting to come around to the P port way of thinking. You
warned me about this:)  I will be totally convinced when we get within 10%
of the famous "one half Lemans engine" output at any rpm setting.  More dyno
time is needed of course and I wonder if it is a money constraint or Dave's
need of the dyno for other purposes?  Is there a possibility of setting it
up on another dyno in another location?  Paul has done a lot of work and it
seems a shame to install it in an aircraft without further tweaking.

I still can't get my mind around the advantages or disadvantages of a
RENESIS P port though.  Someone will have to make one and dyno it to be sure
I guess.

Cheers


Doug

A little of both. Money and time. I am will to do more if we
can find another dyno.
