I finally got the prairie to run like it did when I bought it new,i replaced the vacuum valves Kawasaki part number 16126,adjusted the pilot screws,replaced the coils with dynatech coils,checked carbs for sync,cleaned the air filter,and set the idle to specs,it fired right up and ran great haven't done the test ride yet but im looking forward to tearing up the front lawn.
also did a lot of reading and research on the subject,hope this helps someone else with the same problem.
