    I purchased this carb: http://www.perthmotorisedbicycles.com/online-store/flat-slide-performance-carb-black-air-filter/ a week ago and went for a few rides yesterday and noticed the engine was running way to hot, I checked the spark plug and from the nice tan brown color i was getting from the speed carb now has turned White from using this carb..

    I have a nice stream of blue smoke coming from the exhaust, I am running a oil to fuel ratio of 25:1.. Does anybody know how i can make these type of carbs run richer. Am i looking at finding a different jet?
