Do you mean it runs high revs before settling ? If so it could be an air leak, check plug colour to ensure its not running lean, check all studs are tight and if your running rubber sleeve on your carb check for any splits..

try a bigger pilot jet up 1 or 2 sizes or start by adjusting the mixture screw setting it to a richer position the tickover will probably need turning up at same time ,check the carb isnt touching down onto anything causing vibration of the carb ,i presume its a rubber mounted carb
