Posted July 5, 201014 yr Hi, I own a Wild Star 1600cc. After the engine warmed up I push the choke back and the idle revs go really low. The engine won't cut out it just spins at a low rate. If I am turninf for example in a roundabout in first or second gear (depends on roundabout size), I can't do it without pulling some extra throttle. At idle revs it yanks. Adding a small throttle: everything goes smoothly. She does it in each gear. She is in a very nice condition with low mileage and the carburettor was never opened and everyting else is factory fitted (pipes, air filter, etc). Thank you for your help
July 6, 201014 yr Well, my first thought is that you're either in the wrong gear, or you're not using the powerband correctly. For an average roundabout, I'll be in 2nd gear with about 30-40% throttle. Enough to actually drive the thing round (please don't ever drag in the clutch and coast round corners), but not so much that I'm blasting. My second thought is that, if this the cause of your problems, simply turn the idle up. There should be an idle adjustment screw somewhere, probably on the left of the cylinders. See the owners manual for details. If this still doesn't help, check first your air/fuel mixture and then have your timing checked.
