Non-helpful post #2:
I wonder if enough $$$ has been spent yet on Demon tuning goodies........that a matching carb to one or the other of the original carbs could have been bought and a kit put in it for the same money.
Of course....... in the end that would turn out to be very low cost, since after you had the matching carb....... you’d have the non-matching one to sell(and get the bulk..... or use on another project.
Pop quiz....... changing the squirter/nozzle hole size technically does what???
