I have a scag 52 walk behind with the advantage deck. The issue I am having is that this thing will never start without a shot of carb cleaner? Half the time it takes several rounds of this on and off before it will start. Once it runs for awhile, it starts on the first pull for the rest of the day. Next day, same issue? Also, when I engage the deck it takes a while with it bogging down before it spins right? Any help fellas?
