Is anyone afraid of possible future emisions req's for diesels as applied to our old smokey's? I for one am not because it is very easy to return these old mechanically fueled beasts to stock fueling or less i. e. turn the f. f. screw out and starwheel all the way up,smoke screw disabled etc. I feel like diesels are in a grace period in california for now with no smog check. it is a emmisions loophole of sorts that may eventually get the lasso
