Yes I have heard you can use a Model A carb. Mac's in Buffalo sells several modern air cleaners to put on an original Model A carb. $24.25 to $37.95 and then one for $65.50. They go on the carb mouth and then go up at 90 degrees with the filter on the top of the neck. Replacement paper air filters $9.95 and $10.50. They also sell brand new carbs for $320 to $450 !!!!!!!
