Hot starts can be a problem. With my IO-320 I have a
method that works every time. The engine needs more air when being started
hot, so think of the throttle as an air valve. Don't prime, or if you do,
just for a couple of seconds. Set the throttle about half way full open
and mixture in cutoff. Crank the engine, and it will crank a few more
turns than normal, but when it fires, push the mixture on to less than full and
quickly grab the throttle and get it back to the idle range because when the
engine fires it will start to race. Works good. I lean agressively
on the ground when taxiing. I set about 900 RPM and lean until I get RPM
rise. The plugs will load up with too much fuel in there.
In your case, Steve, when you get a few firing rotations and
then it dies, the plugs are flooded. The engine needed more air during the
start process.
Give it a try.

Subject: [LML] Hot Starts
I have an IO-360 in my Lancair that tends to be tempermental when
trying to restart after shutting down and fueling.
Does anyone have a preferred hot start procedure that works with their
tempermental engine? I've tried the procedure in the handbook and
several other variations.
Normally, I crack the throttle, mixture is ICO, turn boost pump on,
mixture enrichen for a few seconds until fuel flow registers, boost pump
off, mixture ICO then crank. What usually happens with a hot start is
I'll get a few firing prop rotations and that's it, it will just stop.
I've tried several different combinations of mixture and throttle settings
when it starts firing, but nothing works consistently.
thanks
