I'm new to RC and need some help. I have the Hobbico NexStar w/ the OS .46FXi engine and have had much success, though lately I've been having a lot of problems with fuel delivery. I'm not sure what it may be, but I have replaced the fuel lines for good measure and confirmed there are no leaks in the tank or the lines and the tank holds pressure (even pressure tested it underwater!).
Hobbico shipped the plane with the wrong needle in the needle valve housing. I replaced the housing, then realized it was the wrong needle and out of frustration bought a Fox aftermarket needle instead--
What is a good starting point for the low-end mixture adjustment on the carb? How about on the remote needle?
What would cause fuel to flow from the pressure hose INTO the muffler while the engine is running at low-to-mid throttle? This is only at certain RPMs. I noticed it while running the engine in the garage. It only happened twice. When it happened LOTS of fuel was being dumped out the muffler through the pressure tube unburned.
Are plans / pics available to make myself an engine test stand?
Thanks!
