Hey guys,
I've been reading some of Deakin's articles on his mixture/leaning techniques. In one of the articles he discusses hot starts on fuel injected engines. He recommends that you turn the fuel pump on (high), pull the mixture back to ICO, and let it sit for about 60-90 seconds.
Now I have never heard of this procedure before, nor have I ever been taught it by my instructors back when I was training. The principle here is to circulate cool fuel into and through the engine-driven fuel pump, up to the FCU, and then back through the vapour return-lines to the fuel tank.
So, has anyone here ever used this technique? If so, does it work?
Secondly, would this technique work if the mixture control were NOT set to ICO? Or, would this severely flood the engine? My understanding is that as long as the mixture control is at idle-cutoff, the fuel pump simply circulates fuel through the bypass and back to the fuel tank, causing no flooding.
Thanks for all comments,
Chris.
