Trouble with my Model IV Kitfox with the  912S.  I need to replace the throttle cables.  Has anyone had  experience with replacing the cables without having to replace the whole  mechanism?  Let me know.

A repeat request.  I have a model IV with the  912 S engine and the throttle without the vernier. Both cables and their  housings come out of the back of the throttle cartridge.  I don't see  anyway to open the back of the cartridge up to replace the cables.  I  wonder if it would be possible to pull the cables through the cartridge with the  throttle rod if the cables were loose from the carburetors.  In order to  check this out I would have to cut the cables because the ends are all spread  out and will not come through the housings.  Then they would no longer be  useable and I would have to buy a whole new cartridge which I would rather not  do.

  

 Would someone please let me know if the cables will  come out with the throttle rod.  You can email me direct at barry(at)pgtc.com (barry(at)pgtc.com) if you want.

Barry,



I didn't respond earlier because I didn't understand the question.  The 

Model IV throttle assembly has a ridgid rod (wire) from the vernier throttle 

to the center arm on a wide bell crank weldment with arms on each end that 

pass through the firewall to each of the carbs.  From what you describe, the 

throttle has been changed to the version I understand is now used in the 

later model Kitfoxes.  In my mind, this design change was made to eliminate 

some of the welding needed at the factory to simplify kit production.  I 

can't imagine that it was done to simplify or improve throttle performance.



That said, I suspect that if the throttle you have with a splitter is 

similar to the choke linkage, you would need a total replacement.  Although 

the choke splitter will come apart for repairs, it sounds like yours will 

not.

Lowell, sorry I didn't make it clear at first.  It is easy to replace the 

cable in the choke system and it should be in the throttle.  I disconnected 

the throttle cables this morning and pulled the control rod back out of the 

cartridge as far as I could without removing the little clamps from the 

cables and I believe the rod will come all the way out if I cut the cables. 

But I would like to know for sure before I cut them.  I don't like the cable 

they used, it just does not stay together well and much better cable is 

available.



Yes, the old way was better.



Barry
