Hi Paul;

I'm curious what gasket/sealing material was used on the slide throttle.
Did you end up using just hylomar?  paper gasket?

Also what size gap did you end up with between the teflon slide and
aluminum throttle housings?

I ask because I did a quick? prototype with about a ~.003 gap on each
side of the teflon with paper + hylomar, seems to work well enough, but
I suspect it will bind with temperature expansion differential.


Thanks
Cary
