ta.
in the end i worked through the system, everything was okay, so i just tuned
the carb ridiculously lean. once that was done the 79b was out performing
the average califonian car quite spectacularly on emissions.
But anyway, on my little smog info plate attached to the inside of my engine
bay, it says that C0 at idle should be 3.5%. Now i thought that a car had to
pass the emission standards for when it was made, not for now, so how come
they made me tune the carb down to under 1.4%?
i like older engines like wot i learnt on, none of this new fangled gubbins!
;-)
cheers
Joe
