Diagnose my 22R!
Spark plugs about a month old, but BLACK. Not oily, just sooty.
Runs rough when cold, smooths out considerably when up to temperature.
It's a 22R (carburated) engine, in a 1986 Toyota pickup.
Need any other info, just ask.

Sounds to me as though its running rich, plugs should be a sort of straw colour. Don't know if you have auto choke fitted, but if so check that
is not stuck/nackered, if a water temp operated one check its not blocked with s**te. HTH Ray
To make a car go faster, just add lightness. Colin Chapman - OR - fit a bigger engine. Chippy

I figured it was rich by the speed at which the plugs blackened up.
I can't see a level in the carburator sight glass - gunk in the needle valve, broken float, or just idle mixture out of whack?

Do I have to take the carburetter apart to change the float/fuel level, and how do I determine if I've leaned it off too much?
Is there a way to tell if the fuel mixture is right without a fancy computer gadget?
