Posted: Tue Dec 04, 2007 11:55 am Post subject: Throttle to carb connection

I'm concerned that the method I use to secure the throttle cable to the carburetor  on my Jab 2200 is not sufficient or safe. Need some opinions before I redesign the connection. The throttle cable is connected to an ACS  wire grip, PN 05-16000 which is then connected to the carburetor lever. The systems worked well but I'm concerned  the wire grip may let loose at bad time.  Any advice will be appreciated

Hi Dan-

On my installation I used an internally threaded aluminum rod of  

about 3/16" diameter and about 1/2" long, as the connection to the  

carb arm/lever. I did NOT use the questionable stuff that came with  

the engine. I used an Aircraft Spruce vernier throttle control which  

uses a solid wire as the actual link to the carb lever. What the  

3/16" threaded rod does is goes through the carb lever, and allows  

the throttle control wire to pass through it...crossways. The  

internal threads are 8-32, as I recall, threaded all the way through  

the 1/2" long aluminum rod. I then used 8-32 set screws from both  

sides of the rod, and this grips the throttle control wire. I don't  

have any pictures of this at this time...sorry.

I hope I've explained it well enough. It's a pretty simple, but  

effective way of gripping the control wire, and pivots within the  

carb lever as it should. If adjustments are necessary, loosening one  

or both of the set screws will allow for that.

Dan,

        I have the wire grip on my Lycoming powered Kitfox. Seventy hours so

far and no signs of it letting go. I am going to use the same system on my

Jab 3300 engine project. To me, the spring that pulls the throttle to full

open is a hazard and will be removed. With no spring pulling there will be

little force applied to the grip/wire junction.

I think I'd rather have the throttle go to WOT and control the plane  

by using the mag switch, than to have to try to find a landing spot  

with no power. What about an over-water broken throttle control?

Thanks for the information  guys. Since Jay has been successful with the wire grip, I may not change mine. Lynn, how is the internally threaded rod attached to the carb lever. I can't picture it from your comments. More on my set up, I have a ACS vernier throttle which is connected to ACS wire grip in question, the wire grip is then connected to a rod end which is connected to the carb lever. I might add, the carb lever is special design and built by Dave Jalanti. His design add more throw to carb lever which gives more travel to the vernier throttle thus finer adjustments. Heres some photos of my set up.

Dan-

I also have the Dave Jalanti-designed lever/arm. I'm going to the  

hangar in about an hour and I'll shoot some pictures of mine...I  

already have the cowl off. As I recall building it, the internally- 

threaded rod has a head (forgot to mention that last night) and it  

slides through the Jalanti arm, with the throttle wire going through  

the cross hole securing the rod from going back through the arm. Then  

the set screws secure the wire to the rod.

I'll get some pics.

Dan & Lynn,

Not for sure but Lynn's description sounds a lot like the old VW throttle and heater cable connections.

Your installation looks very good, Dan. It sure looks more rugged  

than mine. However, I've got over 400 hours on mine and it hasn't  

given up yet. I tried to find that "grip" device in the Spruce  

catalog, but no such luck.

I just did the search.  It is called wire grip and is located in page 149 of the ACS catalog.

Thanks, Jose...I went there and nothing, but wandering a little  

further I found it on page 159 of both of my Spruce (ACS?) catalogs... 

2006-2007 and 2007-2008. Do you have an older catalog, or is ACS not  

Aircraft Spruce? I'm not being picky, but I've never been able to  

equate ACS with Aircraft Spruce and Specialty Co....the letters just  

don't seem to come out right.



That item seems like a nice way to terminate a control wire.

AirCraft Spruce.  They sell many parts with the ACS brand.  Two of those are the ignition switch and the gascolator.



I found the wire grip searching on their website.  The pdf I got shows page 149.



I also have the adapter from Dave Jalanti, and have been thinking about doing exactly what you did.  However, the wire grip looks elegant...

 Here's my 3rd and last attempt at posting pictures


	


Lynn, your photos came through but with extra files. Those extras are the resource part, including thumbnails, from your Macintosh formatting. To avoid that, select your file, press Apple+I, click the thumbnail in the Info window of the file then click Delete.

Your file icon will now be without thumbnail but the file will be smaller and more 'PC-friendly.'

My NSI Subaru uses two of these wire grips, one for the carb heat, and one 

for the mixture control.  They seem to work very well, but you need to keep 

an eye on them.  One thing they do when gripping the wire is they put a 

bunch of little cuts into it from the gripping jaws.  One day when I pulled 

the carb heat knob it came all the way out, not stopping at the usual 3 

inches.  When I later inspected the wire I found that it broke off right at 

the point where the gripping cuts were.  I use good quality Boden Cables 

too.  Not a real big deal for carb heat.



However, the other wire grip on the mixture control is the one that bothers 

me.  If it broke, my mixture would go to full lean which will allow the 

engine to run at cruise rpm and lower, but not at climb power, the worst 

place.  If it broke at this point, it could be a real problem.  I solved 

that by adding a spring to the mixture arm that, if the cable were to break, 

the arm would go to full rich.



My suggestion is that if you use them, don't put one on the throttle cable. 

Not a good place for something that needs to be nearly 100 percent reliable.

There is a better connector for the throttle control and I'll try to find it 

and post to the list.

Here are a couple more options.  The one I'm actually looking for is a small 

ball joint that has built in redundancy.   I know ACS sells it, but I can't 

find it.

Actually, they call themselves Aircraft Spruce & Specialty COMPANY,  

so ASSC or ASS Company might work. Come to think of it, ASS Company  

is sometimes very descriptive of how they work, especially in the  

catalog department.



Ok, I'll get on the bandwagon with everybody else and accept ACS, but  

it ruffles my anal feathers to break the word "aircraft" into two  

words....but that's just me.

Tell your feathers to relax, Lynn.  According to Kiktionary.com 

<http://en.wiktionary.org/wiki/aircraft>, the term comes from a 

"craft" that operates in the "air".  "Air + craft" is the listed 

etymology.
