POD method cheap , easy works. standard costly, needs better sealing at base, new cage (in this case) , new filter. still only average.
GEt pipe, stick in pipe up and into box seal old hole off around tube for "Still air effect" fit pod inside original box onto tube that comes through hole in box, clean filter at will by lifting off POD, rather than pissing about with wing nut that has mind of own, base that never seems to fit filter in right, and worse still gaps and H/F from stupid shrinking rubber hose to carby falling off all the time cause its old and shrunk. Original is nice, .............pause ....but simple and working is i think easier long term. :O)
