Did the engine have its' spark plugs dropped before start, to release accumulated oil or was it somehow 'pulled through' and at what point was the clutch engaged?
Regards, Flag T
PS, Is there a natops/ pilots' notes hereabouts?

Re: UH-34d start sequence.
To start engine, crank engine for 3-5 seconds. If excessive compression is encountered, drop plugs to drain excess oil/etc. If engine cranks normally, after 5 seconds switch on mags and press primer button [ lightly on warm engine]. When engine fires and runs smoothly, advance mixture to rich. After engine oil temp reaches at least 40C and oil pressure stabilizes, release rotor brake, turn clutch switch on, keep engine rpm above 1500 and accelerate engine to 2000-2400 rpm to get rotor rpm to 1525. Reduce engine rpm to drop below rotor rpm, then accelerate engine to catch and "lockup" rotor and turn clutch switch off. No pre-drop of plugs involved and no way to manually pull engine through since there is no prop to grab. Info taken from Natops [ abbreviated since actual procedures cover approx 6 pages with all the checks and test light operations included]. Hope this helps. Anything else in Natops you are looking for? And, No, the book is not for sale. Semper Fi Joe H

Firing up the engine with stacks full of water makes for an interesting sound. Kind of a phlegm thing.
