The choke cable in the picture is not what I finally used with this carb. I got on eBay and located an older FX Shovelhead choke tube & wire and installed it in place of the original Linkert's choke lever on the top engine bracket. Looks just like it belongs there.... Pull out to Choke, (not hardly ever needed), push in to Run.

Choke tube # 29221-73
Choke Wire # 29216-72
and Knob # 29214-67A
These are all 1973 FX, not FLH numbers.... There is no bracket needed on the carb as the rigid choke tube does all the stationary work.....
Hope this helps, now I've got to run, got a 100" eFeXTeCy to play with this afternoon...... Pics?

Thanks for the info on the choke stuff..

JW Boon in Holland has all the parts NOS, on hand for that task.

Now.........

I took the other carb that I had got for parts out of the parts cleaner tank, and took it apart.

It's in better shape than the first one.........

It has the idle jet marked "C", 0.65mm installed and with a main jet marked C66-157, 1.10mm installed.

JW Boon once again, has all the main jets from 0.90--thru 1.25 in stock, the one I have is pretty much in the middle of the pack and I will probable order the "B" idle jet along with the choke parts.

Thanks for the info (again)!!

George

OK,

I have got the choke parts on order.

Now, I have been looking into many-many posts about these carbs, and some of the sore points that people have about running one that I found are:

1: Float level

2: Fuel overflowing

3: O-ring on main jet, breaking down or tearing on installation

4: No bowl drain..

Now, here's what I am planning to do, you all chime in if I am screwing up OK.

1: Set float level properly: 3/16" with gasket in place.

2: Make sure valves closes off and everything seats properly.

3: I have looked and looked and found VITON o-rings ... gonna use them.

4: Setup bowl on milling machine and skim cut the bowl's boss to make sure its flat, drill & tap and make a sealing washer out of PEEK & install bowl drain bolt.

Thanks to all..

George

I got the fuel bowl's boss spot faced, drilled and tapped for 5/16' x 24 bolt, and made a washer out of PEEK.

Now to get the Viton o-rings to arrive and I can put it all together.

G, Just my take on this....

1) I set my float a little lower at 1/4" using a drill bit as a gauge to help with #2.

2) I could not fix this intermittent problem so I simply made sure to turn off the fuel valve, and letting it idle for a few seconds, before shutting off the engine. ALWAYS shut off the fuel valve when the engine is not running, ALWAYS!.

3) The long a$$ed main jet of the Beneix carbs with its O ring has always been the sore point with these carbs for me, but since my carbby functioned so well, I simply learned to accept this as part of the deal.

4) Right on, Bro,. You got a handle on this one....

These carbs work so well that it's best to overlook the petty stuff, no? It's all part of loving these old machines. If someone thinks these are troublesome, let them have their Twinkies and spend their time and money at their local Stealership, while we fix our own stuff and keep on riding....
