Hmm, they must have invented some new carb. I have never seen an engine where the high starts feeding around 3/4, most of the time at 3/4 throttle you are just about at max rpm unless you have a throttle curve. |

The low jet on a Walbro carbs works the entire range, using a bigger version of the walbro in karting, we have raced on some circuits where to get the most out of the engine,the low jet was out 2 turns and the high jet just cracked open and we still hit 16,800rpm at the end of the straight. Although i haven't tried this on my planes engines as they work well by tuning in the methods described here
