[FC] 140HP aircleaners for FC?

[BBRT]

It may be the older air fliters are restrictive.. they were designed for lo 
po engines. Two things. Size of air inlet passages and secondly, air 
filters.

How about trying a low profile oval on each side like used on two four bbls. 
Small ones. Certainly looking at older small engines of same or larger 
displacement ought to give a good idea what is needed.  We need as much flow 
per side as a 1.4 L engine has.  If we think of a stock engine today, using 
a rectangular type of air filter, perhaps a box off to the side with filter 
to each side of engine, or even with one large inlet and two exit tubes to 
the "plenums of air cleaners" above the carbs would provide enough air flow.
