Carurettor choke control

[Ron Pier]

As Rick suggests, it depends which carb you have. This is mine, but I don't know if I have the correct carb, it was the one that came with the carrier and I had to jury rig the cable like this. I've always thought that it's odd to have to loop it round, but it and the carb work fine. Judging by the spade terminals, I guess my regulator must be post war. I've converted to 12V and again it works fine. If a period looking 12V regulator with screw terminals dropped in my lap I'd swap it. Ron

Hi Tom, Im using Zenith carburetor which is French copy of Stromberg 97. I had to adapt choke control to this carb and its working fine. Please see picture for inspiration.

Thanks for the pictures gents. It looks like I have a replacement carburetor, as it doesn't have the limiter on it, so I'll have to get creative with some brackets like Petr has.

I'll also get a Lucas style regulator on order. I had looked at some solid state ones, which also say they prevent discharging at idle, but they are quite expensive.

I'll post some updates when I've rigged something up. Just the brakes and steering to adjust now and I'll be taking out on the road for the first time!

Cheers,

Tom

Is your generator ford or lucas. If ford (you say it has been converted to a 2 brush) then you will need a regulator suited to the ford (I think) Suggest you take yout generator AND regulator to the auto electrician and get him (her) to sort it out.

Hi Lynn, how do I tell if it’s Ford or Lucas, will it be marked with either name? I think I need to get it off the engine and have a look.

Lucas is longer, has Lucas, model (C42x or C45x) voltage, direction of rotation, year and month. stamped in the case. Ron's regulator is a Lucas RB108 (or similar) The Lucas can be converted to 12 volt by fitting the correct 12 volt armature (if you could find one)
The above statement is wrong. Brain fade.
The Lucas generator is converted to 12 volt by changing the 6v field coils for 12 v field coils. The 6v armature works fine in a 12 volt system (but a 12 volt one cant cope in a 6v system)

Thanks Lynn, my Carrier came from Andrew Rowe over in your part of the world. I believe that he changed the field coil windings to 12V ones. I will go and check what type of generator I have fitted.

In relation to your earlier point of taking it to an auto electrician, I don't know that they exist in the UK anymore. Everything now is repair by replacement, I may be wrong, but finding someone with experience with dynamos and regulators will be quite hard now.

I'm ex REME, and even in the Corps the skills of being able to adjust or repair equipment as opposed to replacing it are no longer taught at the REME trade schools. I think so much equipment is become sealed boxes that there is nothing for technicians to do anymore other than diagnose and replace sealed boxes. Hence the skills are being lost. Which is fine until you can't get the spares!
