I've had this hedge trimmer for a few years now, I bought it used at a pawn shop and it worked flawlessly when I bought it. It has seen minimal use from me over the last 2 years. If I recall it was working last year but also bogging down slightly when i give it throttle. The gas that's been in it is "TruFuel" so that should be ok in terms of sitting for a year...or so it says anyway. The blades move when I can get it revving higher than idle, but when I give it gas it just bogs down and doesn't want to come up to full speed. After a couple of minutes of running it will sort of half work, it still constantly bogs down when I give it gas and will not reach full throttle. I've sprayed the blades with blade cleaner/lubricant, and I've checked the muffler and spark arrestor and they're clean as a whistle/not clogged. Anyone have any other ideas of what can be done to get this thing running like new again?
