my friend just got a new cam, pulley, port n polish, and new 02...

now we adjusted all the values and everything, but when it starts it smokes really bad(exhaust) and after driving it still does a lot....

it smells like fuel, but we were just posting on here to see if anyone had any similar problems or ideas why this is being caused?

we think we may know but we wanna see what people have to say...thanks
