Could somebody load this into MS Word and export it as a pdf
for me. Open Office has problems with it.

Paul--

Saved what you asked as a PDF. Hope it worked.

Thanks--Tom


Thanks Tom. That did the trick.

And thanks to everybody else that also sent the file.
Tom won :)

Okay, at the risk of revealing my ignorance through dumb questions, here
goes:

1) The Tillitson manual says the carb has its own integral fuel pump.  It
seems very unlikely that a pump this size that is driven through "pulsations
of the engine" (i.e. not driven mechanically with a hard link) could
actually deliver sufficient fuel for WOT operation.  What does this pump do
(starting?  acceleration pump?).

2) The manual says "Atmospheric pressure on the vented side pushes the
diaphragm toward the inlet control lever, opening the inlet needle to allow
fuel to enter the metering chamber . . . "  Will this function work when
ambient static air pressure is significantly reduced (at altitude)?

3) Dual carbs:  Just so I understand, what are the
advantages/disadvantages of a dedicated carb per P-port vs both carbs
mounted on a common rail.  The independent carb set up would have the
preferable failure mode (one carb failed would still allow one rotor to run
well and get you safely down.)  Are there ANY advantages to going with a
common rail instead?

Again, sorry for the basic questions.

They are very good questions.

(1) Tillotson makes two types. I will copy the one without the built
in pump and use an external ordinary low pressure fuel pump.
A low pressure regulator can also be used to ease the load
on the Tillotson.

(2) It will if we manually reduce the spring pressure by moving the spring
seat away from the diaphragm.

(3) Well you have a very good point there. Two carbs would allow the engine
to run on one rotor. The rotary runs real rough on one rotor as most people
report but it could extend your glide. However there are a zillion aircraft
engines out there with only one carb. Carbs I think tend to be very reliable.
