TR2/3/3A Set Screw

[Brooklands]

I had driven my TR3B on Saturday, and noticed that the choke cable knob's set screw was sticking out too far, but I forgot to tighten it when I got home. It probably would have been too late anyway, as when I went to drive to the British Car Gathering in Hellertown the next day, the knob pulled right out. I have not yet found this tiny screw, and wondered what size I should search for to fix this...

Hi Dave - until someone gives you specifics, have you tried just running a magnet slowly over the carpet? That should pick up the steel screw.

I plan to do that, but figured getting a spare or two would be good too. I hope all is well for you Tom.

Dave;

Take your choke knob down to your local Ace Hardware store and find a grub screw that fits.

Altho I'm not familiar with all parts on the TR3B, I've never seen a sidescreen choke with a set screw.
Everything I've seen is the style shown in the photos.

Frank,
That probably explains why my choke had a screw and none of the other knobs did...the spring is missing from my choke cable, and is probably another alteration by the previous owner...and the learning process continues.

The replica choke assemblies offered by the known suppliers have that style spring, they don't offer the spring by itself. To my knowledge, no one supplies them. If you find a source, please let me know. I doesn't make sense to buy a whole new choke assembly just for the spring. You might fine a used push-pull switch with the spring intact. (That would also have the little pin as well) As a last resort, the set screw idea isn't a bad alternative. Fill the hole in the knob with JB weld, drill & tap it with a set screw small enough to fit in the hole that the missing pin sat in. Or tap that hole in the choke handle to fit an available size set screw.
