Starting and Running Problem...

Where is the balancer bolt located? Its kinda hard to stop the engine where you want it. And I just want to clarify... Adjust exhaust when closed and intake when open?
The balancer bolt is on the end of the crankshaft. It'll be the large bolt head in the center of the crank pulley (bottom front of the engine). Each individual valve will be adjusted when it's closed. This gives room for expansion and such to keep from bending things.
