[NSRCA-discussion] Characteristic DA behavior?

 That's why real planes have carb heat,,,to keep the venturi warm and so they won't ice up. Same happens here except the carb is kept warm by heat transfer through the case which takes a minute or two.
 I had a 1950 chevy with a split exhaust manifold for twin pipes and had to add a heat tube to the base of the carb to keep it warm for normal operation.The Carb was no longer mounted to the exhaust manifold.
 I'm sure you knew all this,I'm just reviewing.

  Well, 



  It's not always the case, but most times. I haven't been able to correlate it to weather yet. Currently it's rather cold. It's seem that many people recognize the phenomenon.

  The engine is running perfectly in flight. It's just funny that both my DA 50 and DA 150 behave the same!!

  Is this something that is only happening in colder weather?  It's very normal behavior if you had an optimal needle setting in warmer weather and then this starts to happen when it's cold outside. You have to either richen the mixture a bit, probably around 1/8 turn per needle to start, or let it warm up for at least 30 seconds before you try to give it more than a little throttle.  I would richen it a bit to be sure you don't run lean and possibly cut out during flight.

    Hi Guys,



    I was wondering if you experience the same:

    When I start a DA 50 or a DA 150 the first time of the day.



    I close the choke, ignition on and flip till it blurbs Open choke, it starts after maximum 5 flips, but then... It will usually die when I try to rev it up no matter how careful It treat the gas.

    I have to repeat the procedure a second time and then all is OK.





    Any ideas, remarks?



    Patrick
