rich or lean
 

i forget if you stop the car and it shuts off; is that a sign im runnin it too rich or lean? also what are some other signs that mean runnin lean or rich

rich or lean
 

I think your running too rich if the car keeps bogging down, and if you have an excesive amount of smoke coming out of the exhaust. Too lean and there won't be any smoke trail, and the engine's gonna get really hot. Your better off running a little on the rich side, it's not gonna urt to be too rich, but too lean and you'll burn the engine up.
