Repairing my airplane; how to solve Rotax 912 ULS engine vibrations and more - S03 E01

Описание: The closure of my home airport, due to yet another COVID lockdown, opened up the possibilities to give my airplane some TLC. Not that my TL Ultralight TL-96 Star needed a lot of maintenance, but there were some little things and somewhat bigger ones, to take care off. See full description...

I still had to fix the outlet port of the exhaust pipe heat exchanger, that feeds hot air into the cabin (my cabin heating system). That pipe was almost completely rotten away and temporary fixed by the previous owner. So I asked a pilot friend to weld a new steel pipe onto the existing heat exchanger, which worked out pretty well.

A second thing on my to-do list was to replace all the existing spark plugs of my Rotax 912 ULS, to shorten the spark plug leads and to re-attach the spark plug caps to the fresh conducting core of the shortened leads. I've been told by many Rotax mechanics that this could be a possible solution to engine vibration at low RPM (low idle). Despite all my careful work, it wasn't.

So now I'm on the path of carburetor overhaul. I de-installed both BING 64 carburetors from the engine and brought them to another pilot friend, who has a lot of experience in overhauling these types of carbs. Both carburetors will be disassembled, cleaned with an ultrasonic bath, most parts will be replaced with new ones, they get assembled again and installed and configured on my engine. All in all a lot of work.

Hopefully this wil solve the engine vibration problem. If not, it's on to a gearbox overhaul next...

DISCLAIMER

Ever since I received my pilot license, I shared my passion for aviation with a lot (and I mean a lot!) of passengers! Because I enjoy sharing my aviation passion so much, I would like to share it with the rest of the world too! But since taking on 7 billion people as my passenger isn't really practical, sharing my passion via YouTube is... ;)

Where a lot of aviation channels on YouTube focus on General Aviation at the west side of the Atlantic, my channel focuses on Light Sport Aviation in Europe, primarily Holland and Germany. Light Sport Aircraft are also known as 'Microlight Aircraft' or 'Ultralight Aircraft'.

The reason I make these videos is to exchange aviation stories and learn and improve by sharing. And because I love to share!
