Paul,
I'm a bit like yourself, I did it all myself , and although I'm not
terribly
skilled, I had to take my time - I have the basic equipment.
Lets see, $20 for the aluminum and I purchased 10 bearings for $5 each. 4
for the bottom, 4 for the sides ( as per photo) and I only have enough
room
for 2 as a spacer guide for the front of the slide. Another couple of
dollars for screws and washers for the bearings.
I will make my own jets from threaded SS and the fuel cut off the same
way.Not having the complexities of many types of carbs makes it doable.
I did order a velocity stack from Velocity of Sound and I will make a
trombone type inlet for tuning. Thanks for the latest info on lengths etc.
BTW I support both Larry's and Doug's comments on the testing of the RX8
engine - couldn't have said it better myself.
On Machining - perhaps this is another thing for Larry to consider - it
would be so easy on a CNC. He could machine the parts and builders could
assemble their own (labor intensive part). The beauty of this you can make
any size inlet you want.
I now have to machine O-ring grooves - that should be fun!

Got any more pictures. I can't quite figure out what you are doing.
Is it something like this old one I did for the turbo engine?

Paul,
Quite right! I did get the basic ideas from your slide design and then I
researched a dozen or more carbies on the internet. I did however find the
half circle on half circle to give the best linier opening with the shortest
slide length. Also recessing the bearings is better for a number of reasons.
I do have more pictures on the slide I will attach a couple for you - better
still I will include new photo's as it progresses. Perhaps Doug will do the
same.

I also found that shape to be the most compact. I assume that when the
slide is 99% close there is only a small eclipse (new moon) shape remaining
to allow it to idle? Let me build a working prototype before I send you
some pictures. I am trying to make it as small as possible so I can hug the
engine. It can be motorized if desire.
