>We have had warm start problems we believe are caused by fuel boiling in
the
carb float bowls. This is improved by shutting off our Skydrive carb heat
before
taxiing back from landing (I strongly recommend carb heat for the 912S with
XS
cowl), and by opening the coolant inspection door in the cowl after engine
shutdown.<
It is interesting to note that fuel temperature just short of the port carb
will regularly reach 40degC after shutdown even in UK summer temperatures.
If a short turnaround is planned cooling can be aided by leaving the
inspection hatches open in the top cowl. Just remember to close them before
departure. If they are held fully open they should be visible during taxi if
they have been forgotten.
