I have recently bought a pair of Weber 40 type 2’s to fit to my Series II 2L Spider - the plan is to have a normal street car which will also be fun to drive on the occasional twisty road.
I have read several posts on Weber 40 DCOE jetting and have managed to answer most of my own questions, but I am still a little confused by the idle jet settings.
The carbs came with the following:
Choke 30
Secondary Venturi 4.5
Main jets 125
Air correction 160
Emulsion tube F7
Pump jet 40
Starter jet 65F5
Inlet/Exhaust valve (in bottom of well) 50
Inlet needle jet 175
Float 26g
But the idle jets are a mix of 55F8 and 45F8 - one of each in each carb.
So my question is whether I should buy 2 more 55’s or 2 more 45’s, or just average it out and buy 4 50F8?
Many thanks to all those whose posts I have found so helpful - especially Gordon Raymond, AlfaParticle and Alfa7.
Kind regards
