Didn't Nev give you directions? I'm not wanting to bud in on his product and upset him. The key to remember when adjusting it is you'll be using one finger and your thumb. Not much torque. There. His turn freely, I've had the oportunity to adjust one. I'd send him a email. But adjusting is getting the slack out of t bv e cam chain on the throttle body side. Via wrench on front, or pushing forward while in gear. Then turn with the above said appendages lightly until you feel it contact the guide then I back it off a quarter to a half turn and hold it solid while tightening up jam nut with a wrench. I won't go into adjusting while running it might make someone cringe
