First 912 start after a year....

by Keith in 912 / 914 Technical Questions 7 years ago

Planning to start a 912ULS that has been sitting in a hangar for a year. Last fuel in tank was a mixture of 2/3 parts Ethanol Free 90 octane & 1/3 part 100LL avgas

Will first be draining ALL existing fuel from aircraft and replacing with fresh. Then removing and cleaning carb bowls. Any other suggestions such as removing spark plugs and pre-oiling cylinders?

Thank you.

Once the bowls are removed turn the pump on or let it gravity drain to flush fuel lines/system with the new fuel.

Thanks Garrett.

Any benefit to removing spark plugs and spraying oil in the cylinders?

Maybe just a little. Mine sat for about a year with the new SWIFT fuel and all I did wash flush the lines and carb bowls. After running the motor the compression was perfect with almost 400 hours on a 2009 engine last August.
