I just got a fs 90 r 4 mix on Craig's list for a great deal. I installed a new carb and it runs pretty good. I read that you are suppose to check the valve clearance every 135 hours for proper operation. I don't have a service manual, so does anybody have any advice for doing this (valve clearance, etc..) I want to get this running perfect then switch power heads with my severely underpowered Kombi km 55 and see what the attachments can really do
