with the tool is alot faaster , you can pull the pipes off , hook up the tool then adjust the valves , with out the tool you need to fire up the sled , idel it down under 1000 rpms and you should hear your servo motor turn over then kill the sled , pull the pipes off and the manifolrd off , with your finger reach into the front of the cyl. and feel where the valve is on the cyl. wall , it should be flush with the top of the port , if it is not adjust the wire up near the servo motor to get them flush , you might also want to mark with a marker where wide open is , so next year you can just line up the marks and adjust them , i guess now that i read this , it takes about the same amount of time , either way make sure the pipe comes off and feel in there with your fingers to make sure the are flush ....good luck
ecopter , even with the tool , the instructions tell you to take the pipes off and adjust by using your finger as the guide to get them flush ....
