Car is running very rich now, with the idle trim screw all the way in (lean?)
I've looked at the haynes manual section for setting the air fuel (says "take your car to a registered emissions shop to adjust the CO") and have been able to put this together from the sources i've been able to come up with :
1) SU carbs typically have the "jet seat" adjustable through the BOTTOM of the carb float bowl, accessed either through a port, or by removing the entire float bowl itself. The solex 175 CD on my car has no such unscrew-able port, so i'd have to take the whole bowl off to adjust it, IF that is in fact what I have to do.
2) The jet needle itself, attached to the piston and diaphragm has an adjustment on it. It has a slot and a setscrew that can move it up and down 360', since there is only one slot on the threaded jet itself.
My question is, how do i lean this carb out? Without my own CO meter Its "seat of the pants" work, and the idle trim screw in and of itself isn't doing much/enough.
My knowledge has come from the 240 Haynes manual, and this thread i searched and found on here http://forums.turbobricks.com/showthread.php?t=91387&highlight=solex
