Well we got it all set up. Tried to start it and fuel poured
out of all four injectors. Injectors full on all of the time.
No spark. Flodded the engine.  37 pin D submin connector wired
backwards. Way too easy to do. I got  on Tracy case years ago about
this connector. More about that soon. Hopefully we did not
fry Tracy's computer. Will know more about that on Sunday
night when Tracy gets back from a flyin.

BTW if you are building a slide throttle seal it well
around the bottom. You want the fuel to flow into
the engine and not out between the plates. I'll
makes some changes in the drawings to make this easier.

Does anybody know of a good fuel sealant to use between
the plates of the slide throttle?

Sealing of  the slide throttle will have to be 100 per cent effective
as any leaking fuel will end up on the hot exhaust.  This is one place
where  the butterfly throttle body has a major advantage.   Jerry

Only the bottom half needs to be sealed as any raw fuel will then flow
into the engine. You will also have to seal the bottom part of the
butterfly shaft. Same situation.

Paul Lamar

My butterfly shaft is .250 dia that turns in bearings.  No way it will
ever leak.   The slide is a much larger and much more of a problem to
seal,  I think.  I like the slide and I hope it works.  Jerry

A .250 dia shaft is a large obstruction and that is why we are working
so hard on getting the slide throttle to work.

Paul Lamar

Yes,  I enlarged the bore of the throttle body to compensate for the
obstruction of the of the shaft and butterfly plate.  Jerry
