  You are probably talking about Skip Gorman, his web site is revolutionrotary.com
 
 One thing that I forgot to mention is that I use the high pressure fuel injection pumps and use a bypass regulator like a Mallory or a Barry Grant, the low pressure pumps will not flow enough volume and pressure and with the high pressure pump it will hold the pressure that you set it at regardless the fuel flow where the low pressure pumps drop pressure as the flow increases.
  This may be over kill for a street car as you will not be holding full throttle for long durations like we do on aircraft as you have stop signs and corners to go around  not to mention speed limits and cops.

Ok, got some more info from my friend.  I haven=EDt
actually really been working on the car consistantly
so I=EDm sort of trying to help secondhand.

The carb is actually a SK Racing carb which apparently
is a copy of a sidedraft Weber.  Three nights ago he
and I both thoroughly went through it and cleaned it
and it appears to be flowing fuel well since last
night I had him hold up a funnel full of fuel (yaa, I
know, not the safest thing to do!) and feed the carb
by gravity and he said the car seemed to run fine that
way.

Also, he doesn=EDt even have a muffler hooked up so I
don=EDt think there=EDs any problem with flow restriction.
 That sucker is LOUD.   Crazy loud.

The engine (including carb, etc) was built by some guy
named Skip who it seems everyone knows but no one
knows how to get a hold of.  There=EDs another rotary
guy here in town (just across the runway from where I
work) that has a *sweet* setup on a tiny little hotrod
jet boat that is just freakin unbelievable.  It has a
blower on it and just screams.  He=EDs been helping my
friend a little too.

Anyway, I digress=D6 the car had a fuel injected engine
in it so has the fuel injection high pressure pump.
He has a pressure reducer that looks kind of suspect
so his next try is to take the pump out of his other
parts car and try that.  He thinks it=EDs a low pressure
carb pump but isn=EDt sure- how can he tell just by
looking?  Otherwise he=EDs thinking of getting an
aftermarket low pressure pump and just mounting it on
the firewall but then he would have to do something
with the one in the tank.  Suggestions?

Sorry this isn=EDt aircraft guys but really appreciate
your help.

Joa
