it`s not a problem, just i have no idea on how or what to the carbourator every 5 hours.
do you take it apart bit by bit, clean it down, put it back together ect..?
I pull my carb around 20-30 hours of use. After five years, I have never really needed too. In my opinion, checking your carb every five hours is a little much.
