Low revs stuttering

[Dead Eye]

I would have thought that a can of compressed air would be good enough. Just check each jet and make sure there is no dirt / obstruction in them. I cleaned mine out with a fine needle and left them in fresh petrol overnight (no idea if this was a good or bad idea though...). There are a few O-rings on some of the jets if memory serves, but I doubt you'd need to replace them - guess it couldn't hurt though.
