Hello gang, 



do we know for sure if our jabirus are factory tested? I´ve removed one spark plug per cylinder in order to spray it with oil  to keep it OK for my long term storage and i´ve founded dirty as if the were used. Anyone with the same case here? 

 

many thanks ,

Yes, they are tested at the factory.  There should have been a tag on the engine indicating that.

Mine came with a red tag indicating it had been run and was drained of oil.  I also got a test run chart.

Ok, thanks for your answers. I believe the tag is under the engine, right?  I have opened it the other way around so the cylinders are on the top and the plugs easily removed if I need to. I´ll check if I can get the tag. 

 



THANKS!!!

Well Since the engines are run in for an hour and then treated with storage oil, you will see a “dirty” spark plug when you remove them before you start the engine for the first time.

 So if the engine wasn't run at the factory your plugs would look brand new.

Jim,

 I got a question about setting up  a prop for the 3300A engine with the economy tuning kit installed.  As I  see it all one has to do is assure that the ground run RPM at full throttle is  over 2800 RPM and that the inflight RPM full throttle straight and level doesnt  go above 3150-3300.  If these specs are followed we can be assured that we  are running full rich/full power upon takeoff and lean in cruise.  Does  this sound right to you?

Ivan,



Ground static and max in-flight RPM's do not guarantee that you have the right size jets for correct mixture.  Although, being way off the correct mixture will likely cause you to fall short of any RPM targets you have.



Jet sizes aside for now, your static RPM will vary greatly depending on your prop.  I have the Senenich wooden W64ZK49 prop in my 601XL and it gives me a static RPM around 2650.  Max level flight RPM is around 3150.  Other people with the same airframe/prop/engine combination get different results due to the inherent variations.



For in-flight confirmation of mixtures, having EGT information is very helpful.  The Jabiru factory documentation says that the EGT target for takeoff is 1184F and the cruise target is 1256F.  If I remember, Pete from Jabiru recommends takeoff EGT's in the 1200-1250 F range and cruise EGT's in the 1350-1400F range.  Depending on whether you are above or below these targets will tell you that you need to lean or richen your mixture.  



The variation between cylinders will confuse the matter a bit as you may see some cylinders will be above the target and some will be below it.  I have spent a good part of my phase I flight test period trying to find the 'sweet spot.'



Good luck,

Al, I was told that the 3300 I bought was "run in" already and did not require a breakin period. Bill

Dave

Thanks for the info.  My carb tuning and jets should be just perfect since 

they were tuned at the factory with no problem.  So the only variable now is 

geting the prop pitch just right again as it was before it was removed to 

perform maintenance. I got my target RPM's from the SB on the "Economy 

tuning."



By "sweet spot" do you mean peak EGT?



Thanks

Ivan

Ivan,



Depending on the serial number of your engine, I am not so sure that the

factory tuning is "just perfect".

You should follow the service bulletin : JSB018-1 Engine Tuning

I understand.  My serial number engine came complete with the "economy 

tuning kit" installed.  This was confirmed by Pete.

thanks

Ivan,



If you say your jets were tuned at the factory, then I guess you are flying a Jabiru airplane.  (I do not know what you have)  The jets that Jabiru installs onn the production line are meant to work the best for their Jabiru airframes and may, or may not, be optimum for other installations.  When they built my 3300 engine, they did not know what type of airplane it would go in.  As it happens, I put it in a Zodiac 601XL with a fixed pitch wooden prop.  In this application, the load that the engine sees in flight is much different than on a Jabiru airframe.  As Pete at Jabiru USA said up front, and I have confirmed through flight testing, the jets in my 3300 engine were too large (rich).  I have had to go down one size in both the main and needle jets to get the right mixture.



As to finding the 'sweet spot,' that is too complex a discussion to just attach to this thread.  The 601XL installation has all sorts of turbulent airflow into the carb which causes all sorts of variability in mixture to the individual cylinders.  I am close to publishing the results of my testing in a separate post in the near future.



Good luck,

Thanks Dave,

Sorry I did not mention that my application is an S-LSA J-250. All was set 

at the factory.  I had to have my prop removed so when it was placed back on 

the Sensenich ground adjustable pitch is not exactly as it was before.  I 

put a mark on the dial before removing it but the numbers are so close that 

even a bit off changes the pitch-RPM a lot. I so have RPM figures from hours 

of flying so I am just trying to match those again which did just fine for 

the plane as set at the factory.



Thanks

Ivan

Maybe we should all use the method that the Matronics Kitfox List  

uses......include our name, airplane model, engine model, prop size,  

and status, i.e. if we are building or flying, in our signatures.  

That way, all the info is there for others to see, and we don't have  

to remember to include it each time we make a comment about our plane  

and how it is set up.

Well, that idea was also before  on the zenith list due to all the post on accidents. Some builders blamed others and wrongly accused them as "other AC brands competitors" when a crash was posted. 

   

 In my sign, I think, you can get a nice idea about me. Anyway on the Zenith list only a few builder have done that  modification 

  

 Take care,

Lynn,

I think this is a great idea.  I find I can't keep track of this information

and it is very useful when reading and attempting to make use of it.

Thanks, Jim...it wasn't my idea, but it seems to help people keep  

track of who is flying or building what. In the Kitfox group we have  

a couple of moderators who also suggest that we add  the words "do  

not archive" to posts that are merely non-informative in nature, like  

mine here. I think that is pointed out in the Matronics rules for  

posting. That way when future people who are looking up a subject  

find a post of say someone who just had a first flight, they won't  

find a gazillion messages saying "way to go man" or some such  

messages. I usually put "do not archive" right in my signature, then  

when I'm ready to send the message, I can decide whether or not my  

comment, suggestion, or question is worth keeping for the ages, and  

can edit out the last line (the do not archive), or decide that this  

isn't worth reading in the future, and leave the "do not archive"  

intact. If you or others are not aware, Matronics has a system in  

place that sees the "do not archive" line anywhere in the message,  

and will not put that particular message in the archives. It helps  

keep the number of archived messages down to just informative stuff,  

and eliminates the fodder. This group is pretty new and therefore low  

in number of posts, but when it gets bigger, I think Matronics will  

want it moderated too.
