Hi all, I finally got my OS 52 dialed in where it transitions well between idle and full throttle and runs pretty good, got 15 minutes+ on a 6 ounce tank with 1/4 left when I finally shut it down, however I discovered a problem that will be an issue while flying. I ran the plane up on the ground with the wing off so I could play with the settings. I picked it up and pointed the nose up running half and full throttle, and then did simulated moves, up down upside down, and found that when I point the nose down to 45 degrees or so the engine quit, after a couple times doing this I found it to be air in the line being sucked up when the nose is down.
How can I remdedy this? The tank is setup according to the book, and sitting in the correct position. This is in a Kadet LT40.
Or will the fuel be towards the rear of the tank while the plane is moving and be a non issue?
I would ensure the clunk line is of the most flexible fuel line obtainable so when in a downward maneuver, the clunk will fall to the front of the tank. I've found the normal stuff you get on the spool (I use Dubro medium on my engines) isn't super flexible and oftentimes the clunk will not move to the front of the tank. Though most of my aero engines are on airboats and not planes, I dont run into that problem thus the thicker fuel line I use.
ive been flying for about 20 years and i was taught that it was not a good idea for the clunk to move forward..... anyone else care to chime in?
