I am installing the Jabiru 3300 on the 601XL and  have got to the point of connecting up the throttle and choke  cables.

  

 My problem is that the carb. is almost directly in  front of the nose leg, so the cables have to go through a couple of quite sharp  bends.

  

 I would be very interested to hear how others have  routed their cables.

Dave,

I'm going with the dual throttle mod so my installation is a bit different.  Have you looked at the throttle / choke cable installation instructions on the JabiruUSA website?

Good luck!

Dave,



Not sure if you have seen the new Homebuilthelp.com Zenith 601/Jabiru installation video, but it gets covered there.  Jabiru recommends bending the brass cable-end adjuster to help accommodate the bends the cable is required to make.  I am putting in the dual throttle which also requires bending around the center structure.  Although not the best view, I attached the only picture I currently have showing the bent adjusters at the carb for both throttle and choke.



Good luck,

Thanks for the tip - I have been watching Jon's videos, but when I saw the 

section on installing the dual throttles, I decided that I didn't need to 

watch that, as I'm going for the single throttle - WRONG!!



I should have realised that all of Jon's videos are worth watching. I put it 

down to a 'senior moment' (I get a lot of them!)

Hi Dave,



 I am  currently doing the same task.  I found the cable end adjusters included in the FWF from UsJabiru to be completely unusable.  The distance from the carburetor to the nose gear was completely used up by these parts before inserting the cable.



 I decided to make new cable end fittings on my metal lathe.  The new parts extend only one inch from the carburetor bracket.  This made it possible to route the cable around the nose gear column and still get it to the carburetor.  I wound up making three of these fittings since I have dual throttles.  Two were used on the carburetor, and one on the center cable for the dual throttle.



 If you need the dimensions for these parts, I can send you a copy of my little pencil drawing.  Anyone with a lathe and some round brass bar could make them in less than one hour each.  You also will need a thread forming die.  If you don't have a lathe, perhaps you know someone who does or can use a local machine shop's services.  I suppose you could buy the parts somewhere, but I have no idea where to look for them.  I tried McMaster-Carr and failed miserably.



 Good luck,



 Paul

I ran into the same problem and talked with Mark at Jabiru.  We discussed at length and then I just made an extension bracket that moved the throttle cable to the OUTSIDE of the carbie connection point instead of the inside as directed by Jabiru. It worked great! There was no bend in the throttle cable since it lined up directly to the carb while sliding along side the nose gear bracket. It is now smooth and effortless. If I can help, I can send the same pictures that I sent Mark for his edification. But the Choke cable is somewhat 'S' bent so I might have to make one for that also. I will know in the next couple of days.  Wish me luck.

Send them to the Matronics photoshare. Or send them to me and I'll send

them. Attachments sent to the list (even if they do get through) don't

persist very long in the archived e-mail messages.
