Title: 40 Ply P-9 Air Cleaner
Post by: Don St Peter on February 20, 2008, 12:47:53 AM
I have what I thought to be an original "oil bath" type air cleaner, until a recent Florida chapter POC organizational meeting, where I saw an original P-10 with a different configuration. It had a partially exposed element on the back side which allows for a much different air flow into the carb. Since I have been having some idling problems, even with carb overhaul etc. Does anyone know of the proper config.
Thanks
Don

I believe the oil bath was standard on the P10 and optional on the P9 which had a dry element filter.

Just above the idle circuit -- follow the casting up through the body to the lid--- you will find what should be a very small hole which lets air into the idle circuit.  Look down through the area where the choke butterfly is. This hole is a different size on some carbs and if there has been any mixing and matching of lids, there might be your idle problem. Learned that in the school of hard knocks.

Don - when I get home, remind me and I'll send you a photo of the original air cleaner from my 40.

Jim B:
Did you have a chance to get a pic. of your 40 Ply. air cleaner. It may certainly help clear me up on the correct config., air flow etc.
Thanks
