I asked this question in another forum at the end of a long thread and figured it'd get more exposure in here.

I purchased a brand new OS AX .46 for my LT-40. We ran it rich during break in and it ran great. Flew 11 flights. At the end of the last, I pulled the fuel line and let it run down. I then let it drain for a bit. I emptied the fuel tank, closed the throttle all the way and plugged up the exhaust outlet with a cap.

Fast forward 3.5 years and its been sitting inside the airconditioning at my house, out of the elements for all this time. I never put any afterun oil in it or any such measure.

My plan is to just replace the fuel tubing, and fire it up in a few days and run a tank through it. Should I do anything else to it? I know some would recommend pulling it apart and replacing gaskets, but is this really needed after only 3 years and change of sitting inside a climate controlled environment?

I figure a good run on a rich fuel setting for 20 minutes would clean it out and lube it up nicely. I plan to start flying the airplane again in the spring.
