The Picco sites state that the OFNA, Wasp, and Werks Picco 26 carb can use a 7mm, 8mm, and 9mm insert. Has anyone tried changing the insert? Who sells the inserts?
If they are for sale, nitro house would have them. I have read and owned picco .26's and never knew you could change the carb insert. I think with a motor like that, what would be the point, changes in throttle responce would be pretty small, IMO.
