Hi, hope this is the correct place for posting
a very general question about rc fueling.

I do not have an rc engine, but I would like to use
some of the parts to set up a power jet on a 50cc
2 stroke, Yamaha Vino scooter.

Right now I have mounted an adjustable high speed
jet from Traxxas, and would like to set up a separate
fueling system for it. Initially it would be for delivering
a higher oil percentage mixture at full throttle, but
eventually I would also like to experiment with different
fuels.

Trying to keep it simple, I notice that rc carbs, mounted
right on the engine, don't use float bowls. Was wondering
what the mechanism is that keeps fuel delivery correct
anyway.... and apply that to my setup, if possible. Seeing
that I only need to supply fuel under one condition, is just a
gravity feed to the jet acceptable?

I posted here since you guys must have good fuel delivery
even upside down, so are probably more expert on
making sure everything works under all conditions.

many thanks

Walter
