I've posted a couple other threads about this on here and followed everyone's advice (cleaned carbs, fresh gas, new plugs, etc.) and still can't get it to run right. Compression is 100-105-105. At idle it sounds bad, almost like one cylinder isn't firing and it sputters on the top end when I open up the throttle. Anymore suggestions?

Plug caps?
