David Wright

 

hmm sounds like you put in the key part there your assignment...........

think of choke.....
what it does and why it does it or when ( for carberated)

think about airflow during accelleration/crusing there diffrent...

 

Cold starts- rich mixture to aid in starting
Acceleration- rich mixture for power
Cruising- lean mixture for economy and emissions

Thats about as simple as I can explain it.

 

ok thanks so much guys, wicked help
