I am breaking in a tt 46 pro engine, and I am wondering how long it takes to get a reliable low end adjustment. I have run 1 tank of fuel through it, and was tinkering with the low end near the end of the tank, but could not get a smooth transition. Should I just try to run 2-3 tanks of fuel before I worry about the low end?

I am using 15% fuel (I have some 10% if I should switch to that) os#8 plug, 11x5 MA prop, and a tower muffler replacing the stock one. It is on a super sportster.

Thanks,

ron
