New nozzles are not available for the AAZ. Bosch never made them.
It sounds like retarded, or possibly overly advanced timing to me. Does playing with the cold start change the cranking speed at all?
no and sometimes the Coldstart Cable won't go back in...Have to fight with it.
I went a little long between cleaning my K&N air filter and it did exactly what you describe...turning over slow, smoking on startup...even when hot! These things love air even more than fuel! Before doing anything else replace your airfilte with a k&n cone filter (a 3" fits over the end of the stock intake hose perfectly) if that doesn't do it then its fuel related but at least you will have air.
Well the air filter was black lol. I'm going to put one I have here
