Hi all,
I just received my brand new spec made Lectron carb. However the throttle cable definitely needs some attention.
It needs two 90 degree bends (one from both housing and carb), then all the adjusters, cut to length etc. I've looked on Venhill's and there's a million different cable components and its all a tad confusing. I'm in desperate need of a throttle cable as its the last bit that needs doing.
Any suggestions? I'm beyond clueless with throttle cable making

If you've got all the bits and can measure the length accurately, you can do it yourself. I prefer silver solder for its strength, but plumbers' solder works fine if you're careful. You'll need paste flux and a good, hot gas torch. Get a 3/4" steel pipe cap and a nail. Drill a hole in the pipe cap slightly smaller than the nail, file a very slight taper on the pointy end of the nail and drive it in firmly. Cut the head off the nail. That will be clamped in your vise so the pipe cap is poised in the air. Heat it up and fill it with lead solder. Put a terminal on one end of the cable. Unwind the cable a little so the wires are a bit loose. I like to lay a bit of tinned copper wire in there to keep them apart. Move the terminal down so it jams on this wider bit. Heat the pot of solder, heat the terminal, stick the terminal in the flux, then in the molten metal. You should see solder wick up past the terminal. Assemble the fittings and sheath and do the other end.

Hi GB500NZ, that's a great way to do it, I will try that method when i do make it. Im ok with the soldering part, its just all the different fittings/ferrules/adjusters/bends etc that confused me. Now I've bought so many different types of cables, bends and fittings I've got it all sorted.
I know need to now how to correctly measure the cable from the carb slide to the throttle. Any ideas? Is there a certain amount of play it must have? Also how do i correctly fit the outer cable to the ferrules?
