Hi all,

  

 I know that some of you are using my old start up procedures on your 912's.

  

 I am using a modified procedure that works great, as follows:

  

 Ign A & B off.

  

 Throttle full idle.

  

 Pull choke (idle enrichment) and hold, crank enging for 3-5 seconds.

  

 Keep chock(idle enrichment) out, open throttle about 1 1/4 turn on vernier throttle.

  

 Ign A & B on, crank enging, will start immediately, release choke (idle enrichment)  then adjust warm up RPM's.

  

  

 By doing this, you bypass the retarded timing, 6 deg BTDC and rough starts.  Great on min gear box wear.

Boy. I wish my Kitfox started that easily. I'm working on adding a fuel primer to mine. She can be a real bitch some days.

Try this method, make sure your engine is at full idle or enrichment will not work, or not enough to get it started.

Anyone have any great starting tips for a 582? Mine can be a real pain if the temps get below about 60.

If the idle is set very high the enricher circuit (choke) in the carbs doesn't work.  With the idle set at 2500 on my 503 it was almost impossible to start when the temp was below 30 F.  I had to take the air filter off and prime it with a squirt bottle to start.



I finally broke down and installed a primer this winter.  No matter how long it has set or how cold it is, it starts first blade with the primer.

I was flying today  -10C  -- 

3 shots of primer and fires right up .

get ready with more primer shots until it warms a bit or use enricher .



I hand propped  mine as my battery is 5 years old and does not give enough 

rpm to fire the ducati ignition - you need about 275 rpm min to get a fire.

With the throttle all the way out it will idle a little below 2000 which is way lower then I manually set idle, about 2600-3000.  I may just have to look into a primer.  When one was not installed when I bought the plane I guess I just figured it wasn't needed on this engine.  Probably has more to do with the fact that it was built in South Florida, huh?

Exactly, James.  The farther north the more you need a primer.  Up here in 

northern Michigan it's a must.  If you're jetted right and get the hang of a 

primer it'll start almost immediately each time no matter how cold.  I've 

often wondered why they aren't used on 912x , or are they.

I don't have a primer on my 912.  I haven't had a situation where I needed one to start this winter.  Having a good, fully charged, battery helps, too.



(I've put on over 20 hours of ski flying, so far this winter with many cold starts.)

You guys must not be running clutches. I idle at 1500 and have no 

problem starting at any temperature the battery will support. (Down 

to about 25F here in sunny SoCal.) I use the standard choke.

With engine not running, I had fuel leaking from one carb on my 503. Spent 2 hours trouble-shooting. It turned out to be running in from the primer line. I think my first move will be to remove the primer. Should I just cap the points where the lines entered the carburators?
