Trouble with my Saito FA-62. Been flying my Hangar 9 Piper J3 Cub for a few years now with a Saito FA-62 four stroke engine. Was running great for a long time. But recently it’s been stalling when the tank gets to be about halfway full. Well, I did a lot of searching online and checking RC Plane Forums such as RC Universe and RC Groups for some advice and I got a few nice viewer comments with some tips (thanks!). The popular advice was that there must be a leak in the fuel line inside the tank that when the fuel drops to half tank, the line draws air which leans the mixture and stalls the engine. This made sense to me. So in this video I check all of the fuel, muffler pressure, and filler lines inside and out of the Hangar 9 fuel tank. I check all connections to look for leaks. Unfortunately I did not see any evidence for a cracked line anywhere and all of the lines were free and clear. But to be safe, I decided to replace the tank and lines with a new set. So in the later part of the video I show how I typically assemble a glow fuel tank. I replace the Hangar 9 tank with a nice Du-Bro 8 oz tank and show how I set it up.
Since I didn't identify why the Saito 62 was stalling, I decided that I will now check the Saito engine for other issues. In the next video I will check the glow plug, show how I set the valve lash, and check the low-speed needle and high-speed needle settings on the carburetor. Hopefully I will find out why this engine keeps stalling and fix it. Stay tuned.
I have been building, flying, crashing, modifying, and repairing radio control planes (RC Planes) for many years and enjoy sharing what I do with the radio control plane community, so I started RC Plane Tech channel for fun. I am not an expert, there are many different techniques to building radio control planes. A good way to learn about flying and building rc planes is to see what others are doing, that's what I do and that's why I like to share what I do. Thanks for watching my channel. Have fun!
