DLE 30cc. Part 1/2 Rebuild After Crash.

The owner of this engine got it as a gift. The engine was in a crash and was in storage for a long time.
There was noticeable damage to the piston ring which I replaced after cleaning the sleeve. I polished the read valve and fixed the throttle arm and serviced the carburetor.
The bearings still looked good and after assembly and the first test run some other problems arose that I will address in the next video.

some commentary would be preferable to the music - superb video showcasing your knowledge and engineering skills. outstanding

Noted! Thanks. I will work on it.

Good video, but without any commentary I have some questions. What does adding the air inlet to the metering diaphragm cover do that the hole that was already there didn't do? Also, you drilled a new hole to make the pump work? Was the pump never working? Was that a factory mistake not having that hole there? Thanks

Hi. Yes. The pump did not work and I had to drill the hole to make it work. It must be a factory problem. When the plane flies the pressure in the cowl changes(that is if it is not flown open like on a stick ) So if you tune the engine on the ground static the pressure inside the cowl is different from when it flies and the metering valve will work differently. Adding the nipple allows you to connect some fuel tubing or any suitable tubing, and run it through the firewall into the fuselage where the pressure will be more stable. The end can be inserted into an old pill container with holes and secured somewhere out of the way. This has solved some of my tuning problems.
