My new 36" exmark metro is giving me a hard time starting in the morning. Needs a good 10 or 12 pulls to get it going. After that it's fine and goes on the first or second pull the rest of the day. Just started doing this last week. It's less then 3 months old. I know I can take it to the dealer, but just thought I'd check here first to see if anyone has any input. Anyone?
