Small Engines (Lawn Mowers, etc.): chain saw timing, crankshaft, flywheel

Question
I have a mccullough 110 chain saw with points & condenser and wood like to know what the points gap should be. The flywheel has a arrow on it but cant find a point to set it to on the block.  

Answer
 Hello Rich:

 There is a Lobe on the Crankshaft that Opens and Closes the Point Set. Turn the Crankshaft Until the Lobe is Under the Point Set Lift and then Set the Point Set to .015in. Hope this Helps. I am here if you Require more Assistance. Thanks.

 Good Luck

 Respectfully

 John
