One of the adjustments on this carb is done by regulating fuel stream (pilot screw) into mixing chamber, so yes.
There should be a #36 lowjet and #108 mainjet.
But only up to 1/5 - 1/4 of performance depends on low jet and pilot screw, simply said.
HOW TO:
-warm motor: preadjust pilot screw to 2.5 turns out
1) regulate the idle with pilot screw on its HIGHEST revvs
2) regulate at THROTTLE STOP screw (where throttle cable meets carb) to ca. 1700 rpm
Mainjet takes over fuel supply from 1/5 - 1/4 of throttle to WOT, from there on your pilot screw and low jet are theoretically jobless.
Testing:
A) workshop with a testing equippment (NOX tester)
B) sparkplug out and see whether its nicely grayish/ brownish or greasy oily.
Any motor will have an oily plug when idling only, so ride it at least 20 min and then stop the motor immedeately, NO IDLING before testing.
