Air filter for Model A

[Gold Digger]

I've got an oil bath air cleaner off an old hay baler engine that I put on my 2-door 29 back 43 years ago and works fine but have always wondered if it has the right balance of air. Didn't know about those things back when. I did worry about sucking the oil out of it when I would get up to 70 mph but never had that problem either.
