Thanks Gary, power to the argument for hot air carb heat.=0A=0AI forgot to
mention I do use carb heat as I reduce power below 2000.=0AI'd feel lost wi
thout it but as Gary's says and my experience is, ice forms best at low rev
s when there is the biggest pressure drop across the carby.=0A=0ARememberin
g of course, foggy mistys days are not necessarily the worst days for carb
icing conditions. They are just when you think about it...=0A=0AAs with all
these things it's your plane and you can do what you like!=0A=0ARegards, C

live,=0AMy engine never shut down at cruise power settings,although it did
get really rough as it ingested the ice chunks.If there is fog the elements
are ripe for ice,but you can have ice at temps in the 60'sF if the humidit
y is high.The only time it might cause the engine to quit would probably be
at reduced power settings and almost for sure at idle on decent.=0AG.Aman

I was having trouble starting my 3300 whenever it was below 40. The US Jabiru website
has an article about drilling out the choke jet to alleviate this problem.
This works great for me as the engine has started almost immediately every
time even down to 15 degrees OAT.
