i've ran it with the plate at the base of the adaptor(4150) going to a dominator.(i had to.. thats which nos plate i had.i couldn't afford a dominator plate)..don't know if it's ideal but i had NO issues and i was spraying alot more than your talking about using. and as far as the timing goes there are tons of theories and tons of racers trying different tune-ups...try running a search for anything Monte Smith has to say on the subject and you'll get alot of useful info..
