Hi all.

Hope you guys can help. Is it needed to install an on board glow driver for an invert mounted YS engine? I got it to idle at 2400 RPM
for about 10 seconds before it dies out. Tried adjusting every settings, but no luck. All seals and diaphragm are new. I also noticed that fuel
was leaking out of the carb when I try to prime it for starting, but no fuel get sucked into the combustion chamber. I had to flip the plane upside down
to get it to start, then flip it back. What can be wrong? Thanks in advance for all the tips.
