Hmmm, this carb conversion sounds a bit bodgy. Whatever you do, don't cap it
-- the pressure will build up and blow out the dipstick, like as not. While
there should be a more elegant and functional solution for crankcase
ventilation, the relative rarity of this installation may make sound advice
on the subject difficult to come by. But your main problem, to my mind, is
excess blowby -- that "nasty smelling smoke" is blowing by the rings. By the
time you fix that problem, you will have had plenty of time to sort out the
carb plumbing.
