My throttle cables are a bit stiff, particularly when reducing power at low power settings.  Increasing power is fine.  I think I have the cable routing the best I can achieve and the binding is definitely in the cables and not the throttle box itself.  The throttle lever arms on the carbs seem nice and free and the springs seem in good order (the throttle opens nice and smoothly).



With the cables dismantled should I lubricate the cables?  Squirt some WD40 down the outers perhaps?  Currently they are installed dry.



Cheers, Jon

Hi Jon,

 In the pas I have the same problem I take another way, Piano wire.

 I use this perfect solution since 10 years if you are interested I  send to you a Pdf Doc off line.

Me too please – I remember seeing several threads about this

BTW I have just had an issue which caused my heart rate to go up a tad.  One of the cables was sticking causing one throttle to be about 90% while the other was 100%.  Caused significant vibration…

I replaced the cable sheaths that came with the kit and went to the bike shop and bought Teflon lined sheaths. Smooth.

Teflon lined cable sheath is very nice and smooth but I would be cautious about using it.  I had some installed on my heater inlet valve (above and behind the radiator duct, so not near the exhaust).  At some stage the Teflon melted and locked the cable solid.  Not something you would want to happen on a throttle cable.  It could be that the cable I used was sub standard.

As it goes I just replaced my cables last Sunday. (Believe it ore not, it took me 5 hours. )

I have been alarmed as the right carburetor did not fully open as I engaged the throttle in the cold hangar. The part outside of the housing bend instead of moving into the housing. Don't want to experience this during a flight!

I also used high end bike parts (Jagwire) to replace them. (The original cables have got a very poor quality). 

I want to encourage at least the builders that have not already installed the 

cables that came with the kit to use a better quality ones.

Now the cables are pulled by the carburetor spring instead of pushed by the throttle arm.

Perhaps some testing would be a good idea.

The sheaths I installed during the build have performed perfectly for nearly 400hours now.

Hi! Juergen,

It is my understanding that the original type of cables should always have

been spring pulled to fully open (in the event of cable breaking ) at no

time were they to be used in the "push" mode. In my opinion the most likely

cables to be used to have a push or pull capability would be a Boden cable

specifically designed for such application and also specifically length

sized also, but as good as they are it would be unlikely that the existing

springs would be suitable under such arrangement .

Regards

Hello Bob,



due to my basic English I am not sure what you want to tell me.

I too think that the cables always should be pulled by the springs.

In my case the were pushed caused by to high friction.

That´s why I replaced them.

But maybe I got something wrong.

Hi! Juergen

Your first e-mail on the subject seemed to indicate that before you had the

plane the cables were PUSHED by the throttle then you changed it.#

yes Bob,



they have been pushed due to a suboptimal routing and the high inner friction. Now with the old, cold grease the possible, dangerous potential became obvious.

I am just getting checked out on G-UMPY after build. I used piano wire from Airworld/jodel as the originals started kinking. Trouble is these are now stiff and sticking. I had to stop flying dismantle, oil and re route. It seems they should really be longer and either PFTE coated wire or a coated housing. The orginal stranded ones are lower resistance but maybe it was the routing that was the real culprit. Not sure whats best now.

Graeme,



I replaced my kinked, stranded wire with solid, teflon coated wire purchased from McMaster-Carr here in the States ( McMaster.com ).  There's probably a similar product available in the U.K.  It seems to be working well, but only 25 hrs on it so far.  Hopefully, more time will be accumulated starting next month.



If I were doing again today, I'd probably go with hi-tech, teflon, cycle brake cable and sheath ( Amazon.com search: teflon brake cable ).  



Perhaps I'll try that over next winter down time.
