The Flavia engine has been repaired (new crankshaft, conrod and bearings) and installed on the new engine test stand and has been connected to the power meter. At the beginning it did not start because the ignition sequence was wrong. And I swear I did not change it!!! Once this problem had been solved, I shortly turned it up to 2500 rpm without the cooling water of the Schenck being running. The instrument did not move at all.
After turning on the water, the instrument woke up, while the engine stopped fairly quickly. The load lever of the power meter had been set too high. At that time, I got really nervous with the propshaft of the power meter idling right in front of me. Turned down the load with the remote control and started the engine again.
Did some playing with the engine revs and the power meter load but honestly was feared by the incredible noise the engine produced without exhaust installed while I had to stand very close to the rotating parts in order to operate the carburetor throttle for setting the revs. Made a few photos using the rc of the camera. The square instrument in the switch cabinet shows the revs. Engine revs and load interact and it needs some experience to balance them for correct measurement which I did not manage this time.
I made some jokes about the cable rc of the Schenck before, but now I see its legitimation. Even if you are not a milquetoast as I am it is difficult to observe the instruments, set the engine revs and the power meter load simultaneously while standing close to the roaring engine.
Each test brings a gain of knowledge! Still very many things to learn in order to get it right!
Next thing to be made is a remote control for operating the throttle and some emergency cutout to prevent going berserk of the engine. The throttle actuating will have to be sensitive and other than the pedal on the car will have to keep the position. The cutout should work on two features at least (ignition and fuel pump).
There is a spare Flaminia 2.5 3C without carbs on the shelf. I think I will install a 3B carb and put that on the meter next.
Just for reference: at maximum output (90hp) the meter should show 120N at 5500 rpm.
PS The engine frame is on wheels which allows to roll it under the chain hoist to install the engine, but during power metering it could be settled better. Will mount machine feet which can be lifted for taxiing
