Paul,

I have been reviewing my p-porting notes.  Could you tell me where the
throttle is on these pictures of Allen Toole's engine is.  I am guessing it
must be in the intake chamber surrounding the air filter but it is not
shown.


Thanks

There are two butterflies almost in the rotor housings.
The pressure drop across these and the smaller size
of the runners, about 1.75" OD instead of two inches OD,
limits the HP to about 215 at 6500 RPM instead of 240
to 250 at 6500 RPM we got using 2 inch OD runners and
a Weber carb. You will get more with the slide throttle.
