Timing for Victas is 1/8" before top dead centre unless you pull the head off you have to do it by eye through the spark plug hole. With the contacts just beginning to open have a look where the piston is in the bore.
Now rotate the crank a little more and it should move up a fraction to be at the very top of the stroke or top dead centre. If yours does this then leave it alone.
See how you get on
