I am trying to figure out what my hot start procedure should be on my O-320 (fitted on my RV4) and perhaps you can help me out.
Yesterday, I tried to start my engine 5-6mns after having it off (with mags off rather than leaning as I intended to restart shortly), no priming, fuel pump on, ? inch throttle : it started for 1 second and then died. Couldn?t restart it.
5 mins later after ventilating the engine (mags off, fuel off, full throttle,10 turns of prop manually opposite) still nothing.
1hr later ventilating again, little bit of priming and it finally started.
Some guys told me that it is a fairly common feature: when the engine is switched off, the heat of the magnetos actually increases, sometimes to a level where they become inoperative. The heat of the engine would actually be transferred to the magnetos when they are no longer cooled by their special venting?Does this make sense?
What?s the best advice for carburetted O-320 hot start procedure?
