Last week, we ran all four engines for a few hours until we ran out of fuel.
We will be having the airplane weighed soon.
They all ran fine, but #3 never really cleared of smoke. There are a few oil leaks to take care of on it, and of course, since it hadnt been run in 20 years or so, we'll have to do another compression test on it to see what's going on.
We suspect a few things, a sticky primer solenoid, resulting in a rich mixture, a stuck ring possibly, just a rich mixture in general, and of course, oil leaks. We already pulled all the screens and they are clean and metal free.
We will sort out the issues, but overall, the engines seem like they're in good shape.
Here's a vide shot of the first 20 minute run.
