140 RX air cleaner

[Rcmaster199 at aol.com]

Another option is to search for screen packing material onthe Internet.  What 
you are looking for is screen material used in thermoplastic extruders;  it's 
used as a filtering medium for the plastic melt, and you can probably get  an 
exact circle to fit your specific carb.
 
There are a variety of mesh types offered. A 60 mesh screen works okay  for 
most runways or a 100 mesh for more dusty areas. Material is usually  stainless 
steel but brass is also offered. Another place to look is WWGrainger  or 
McMaster Carr.
 
What I do is form the screen to fit over the carb, and lock it with an  
o-ring. It works easily with hand snips.  Easy to put on or take off, and I  have 
never lost one of these from vibration or what have you.

My motor  ingested a few of the foam filters over time. So I stole the wire 
gauze  element from the hose on the washing machine, and trimmed the black 
rubber  edges of the part down to a smaller size.

They work great in the  Bru-Line rubber fitting. If you put the curvature of 
the mesh to the  outside it deflects the dirt to the sides and keeps the 
filter pretty  clear.

Regards,

Eric.

P.S. Please replace the filter and  reconnect the hose before your wife use 
the washing  machine. My  former wife did not cite the incident in the 
divorce settlement, but I  knew that I was never forgiven. (No sense of humor 
that  one).
