Looking for a new Carb for my essex V6. going to go back to auto choke while im at it

looking online I have found a few variants but no explanation on what the difference is.

does anyone know what the difference is between a "38 DGAS 3C" and a "38 DGAS"

maybe a 38DGAS is a 3C but not all sellers say it ? does the 3C make any difference?

I can't be sure of the model numbers but if I remember correctly the earlier ones didn't have anti stall.

3C added the tamperproof screws (I think anti-stall came in earlier) but I'd wager they aren't fitted on a new one.

Thanks folks.
Looks like the dgas 18930.035 has tamper proof screws but dgms 18930.086 does not.

Maybe tamper proof would be a good thing. Ive been playing with them for a decade and never been able to get the thing to run well.

They are both 'tamper proof ready' designs. The mixture screw is shrouded so that it can be sealed with a plug after setting up. The DGMS is a factory ' bodge ' to suit the strange British fetish for wanting to cock up the cold running. :mrgreen: To set the fast idle requires a hammer and that is not a joke.

I have received your query Joe and should be able to get you one, just waiting on a supplier.
