HI I'm running on pump feul. But there are no inv on how to jet it on kart motor. And not a lot of people can help. Bullfrog sells a carb of the shelf that tuned and jetted. But doesn't reply back. And I'm siting in south Africa.I'm not that familiar with that carburetor. I do know it takes about twice as much alcohol as gasoline to burn correctly. Increase the jet size "area" by twice is good for a B and S carb. Remember, not the diameter, but the area. Pi R squared.
