Thanks for all your help but the answer was a bit wierd. I guess a
small part of the foam air filter came loose and got sucked into the
cylinder and interfered with firing and let the valves leak.

I was trying the 'oil trick' (thanks Hippie...) and got up to 70#
compression when I added a bit of way oil and was able to get a
pop-pop-pop when cranking. Found some black gunk on top of the piston
and tried burning it out. No luck but did fix my eyebrows

So I tried a bit of carb cleaner in the plug hole and an oxygen stream
from my oxy torch in the carb and cranked; got a steady stream of
pop-pops and kept cranking until the rpms picked up a bit then let it
run on its own until I got more revs, then turned the Oxy off and let it
idle by itself. It apparently burned up/blew out the gunk fairly
quickly and began operating normally. The Oxy injection allowed easier
hotter combustion to let the engine run and burn/flush the gunk out.

I shut it down to put the valve covers back on and checked the
compression - was back to the 100# it used to run. Restarted easily and
everything appears normal now. All from a crappy foam air filter. I
replaced the element with a piece of pantyhose, would like to find a
pleated filter to fit (dealer doesn't list any, even aftermarket).

Thanks for everyone's help

Nearly any dirt bike shop, both physical and online will have
aftermarket pleated filters. Including JC Whitney..well..they did last
time I ordered from them

I've found lots for other ATVs but not yet for a 83 Kawasaki 3-wheeler
250 Prairie. There must be a cross reference somewhere as to what other
bike/atv uses the same filter.


Its not particularly hard to make an adapter..we are machinists after

machine for one of the local cops yesterday..with much
trepidation..but it came out rather nicely if Imaysaysomyself
