My wife has a 2001 blaster and ever since I bought it I've this problem. First off, its hard as hell to start if its been sitting for any amount time. Second, when I do get it started it runs and idles fine until I give it a little gas and when I let of the throttle it takes forever to idle down. besides this problem it runs fine, has 120 compression, passed a leak down, I've tried changing the jetting and still the same deal. the engine is completely stock with the tors removed, new stock carb, fmf power core pipe, and k&n filter. Ive also tested the electrical and the only thing that's not to spec is the ignition coil but I think that may be due to the meter I'm using any help would be greatly appreciated. Thanks
