Ok,
I got a TT Pro 46. Everything is running OK, but I have a little problem in low to high throttle transition. It bogs down. We managed to peak out at top end (high end needle) and it screams.
So basically my next step would be to adjust the low end needle? Could it be running too rich at the low end? If so, do I close the low end needle valve to lean it out? If that is true, how much do I lean it? If going by degrees should I lean it out about 10-20 degrees (1/8th of a turn).
Should this adjustment be done while the engine is running or shut it down, make the adjustment, and then just restart it to check?
Thanks!
PS. What is WOT?

At low throttle, pinch the fuel line and see if the rpm's come up. If they do, lean the low end until they barely come up and then check your transition. If the engine dies or hesitates at this point open the low needle until you have a smooth transition, then check the high speed needle again.
