PD46C modify the choke
« on: April 15, 2023, 07:33:23 AM »
Hello, curious if anyone has ever attempted to modify the PD46C choke. It uses a cable and I find it doesn't work great. I was thinking of modifying it to work like older carbs where there's a lever on the metal rod connecting the butterfly valves. Basically a more direct connection.

The rod connecting them is solid metal I assume? So I could possibly remove the cap at the end and attach a small lever somehow. Has anyone attempted this before? Is it possible they used the same hardware from the older carbs and I'll find a way to attach the lever under the cap?

I'll attach a picture of the cap I'm referring to

The cable link also opperates the tickover raise cam, i dont think its from the shaft but could be wrong

 I'd have a look at making the cable work properly. I found a replacement cable for one of my bikes and it's working fine. I'm usually disappointed when I try to re-invent the wheel.
