New to the site looking for a little help.My 1988 cr 125 is fouling plugs like crazy.I recently bought it and was told it has rebuilt topend.I've changed the reeds,leaned fuel to 40-1,completely cleaned the carb,and air filter.I have done a compression test,after about 15 kicks it stopped at 160 psi,it then held that for close to 10 minutes.It will run great for about an hour then just stop running.I'll put a new plug in,it will start right up and run great for another hour or so.It will go thru 3-4 plugs in a good afternoon,I don't know
what else to do but plant flowers around my new yard ornament,please someone help.
