Posted for erosiak@comcast.net:
I have not had problems starting the TSIO-550E in my ES hot or cold. Cold is
easy, the large Continentals like to be primed. Unless it hasn't started in
some time, I usually don't see any sniffle valve draining. I had no problems
with the
TSIO-520 in the T210 we owned prior either.
Hot starts depend upon how long the plane has been sitting. After 30 minutes
or
so, on a very hot day, pulling the mixture and cooling the fuel pump via
running
the high boast seems to work well. However, I have found on my ES that if I
simply provide full rich mixture, and crack the throttle at start, (no prime)
and turn the key she will always catch within a few turns. Then the key to
keeping her running is a few shots of prime, or low boast if it is very hot.
Just remember to turn off the low boast before takeoff.
A few years ago I did a fuel pressure adjustment with Dave Saylor of
Aircrafters
in Watsonville CA., which required numerous start and stops on a very warm
day.
It started every time, using the primer or low boast pump, as required.
When I park for a short stopover I try to point into the wind and always open
the oil filler door too. So far so good, 275 hours later.

<<But over-priming is so commonplace that TCM has required us to install a
drainage system specifically to handle this problem. Am I the only one
who finds it crazy to install sniffle valves in our 21st century
airplanes? SNIFFLE VALVES! We have somehow been conditioned to accept
that it is normal for our engines to dump raw fuel on the ramp during
startup!>>
