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.

This looks very good, but I have a question.  I think looking at your
drawings and the pictures you have the unit set up to open when you PULL
on the clevis, am I right?  Normally on the dash you push to accelerate,
will you have a mechanical reversing unit or bellcrank somewhere in the
cable line, or could you make the main plates a tad longer so the slide
could open when you push?  I am hoping this is helpful.

It just depends on where you place the 1 and 7/8 holes on the Teflon
slide it self. Push or pull you option.

I like to add a comments on PP.
I can only confirm what Paul is getting on PP testing. PP does work! it is
not sensitive to port timing. It runs with carbs just the same. Potential
improvements are mainly limited to tweeking as in any engine where there is
not much data available to start out with. Throttle response is not a
problem, even out from a bad idle situation. It is allways smooth.
Extreme ideas such as combination  PP and side port are a totally different
story. I tried this and I could not make it work.
Noise does not seem to be different from side ports. I am running my
tangential muffler on the test stand in AC configuration, and the noise is
tollerable.

On fuel consumption, it is only BSFC that count, ther rest is airplane and
settings specific.
I only wish I could have access to a real dyno soon.
The testing I do presently is for making sure the engine mods on the weight
savings are holding up, before i go to final and flyable components.

getting too many bounces. Seems like if I put the name of the bad
ISP in the message they bounce it :)
