I have a Moroso 13 x 3 air filter that where the base of the filter is an inch or so below top of the carb.
I was running a Holler 700 (4778-2) on a Torker and the engine screen just touched the airfilter. A small piece of rubber between the two stopped any buzzing noises.
With a Performer this airfilter is too low and presses on the distributor.
Sorry I don't have any part numbers.
