I recently returned from a summer trip to Germany and Austria in G-IANI
wonderful trip but temperatures at 2000 ft rose in the cockpit to 44 deg C
and CO2 from the exhaust bothered me most of the time..
When on the ground the 914 was a problem to start probably by fuel being
evaporated
in the carbs and consequential vapour lock
I have the Standard NACA vents (broken but open) but these didnt work at all
well.
Ian gave me a Mecaplex vent which unfortunalty doesnt match the curve of the
screen and maybe it would if fitted foul the locking handle.
During the winter months I would like to redress the situation and would be
grateful
for advice, in screen vents for example. Is it feasible to block or restrict
the entrance where the flap drive enters the fuselage? If this is possible
the CO2 problem might improve
Any help or tips much appreciated.
I do have the vapour return line installed back to the tank as required by the
LAA and was recently checked and a logbook entry made.
Once started from cold the 914 ran faultlessly even in those high temperatures
Both cylinder head and oil temperatures were within limits.
