White Smoke ?
My truck smokes a little white when I first start up and when i rev it while stopped ..... is this bad or is it just because my smoke screw hasn't been tampered with....Other than this it runs awesome shes a 1993 w250
I am going to try and turn up the fuel screw on monday and see if it puts some darker smoke into it ..... haha ... do you think that it will harm the engine ?
