Yes, as mentioned above it depends greatly on the type and flavor of the 'POP'
Was it a Champagne cork pop or Coke or Pepsi??
The Kohler bible (service manual) is available online for my kind of price- FREE! D/L and save it to your H/D.. It makes great reading to soothe you after a stressful day of wondering what the heck happened to your tractor!
