Mods so far: Sigma Turbo Globe Montego wheels (polished), wooden steering wheel with rare Sigma greek symbol horn button from a Peter Wherrett Sigma, NOS bonnet and boot SE badges, NOS GE Sigma GL front and rear bumpers (no ugly rubber bump strips here, just full chrome goodness).

I'm currently working on the finishing touches of fitting twin Solex carbies complete with extremely rare Japanese-market stock airbox, so it should be much easier to register the car if it looks stock. I've also fitted an electric fuel pump and glass/chrome fuel filter.

I also already have a pair of chrome aftermarket airfilters to be fitted after I get the car registered.

Now to the sad stuff. The car was running perfect with the stock carbie. Not a bit of engine smoke, started first time every time and didn't miss a beat. Now with the dual Solex carbies, the car is a bit harder to start on cold weather due to the mechanical chokes not being connected (in the process of fixing that though). Once the car warms up a bit, I can get it to idle and rev without misfire for about 10 to 15 seconds then it seems to start strugling more and more until it stalls, and if I try to rev it it seems to make things worse and cause it to stall even quicker. Can anyone help? Am I right to think its just getting too much fuel? Could it be the secondaries vaccuum solenoid being stuck on open? The carbies seem to be getting correct amount of fuel and I don't think the fuel pressure is too high as the electric pump I'm running runs at 4 to 7 psi. Do I need a pressure regulator?
Any help, suggestions and comments would be greatly appreciated.
