No. Because the spark is triggered at the crank, there is a spark on every TDC, so it matters not which one you use to time the cams. In an engine where spark is triggered by a distributor or from another device attached to the camshaft(s), you get one spark every other rotation, which makes it possible to choose the wrong TDC when setting up the ignition. Can't happen to yours.

first off check your spark

if you got spark, put a little amount of gas straight into spark plug hole

if it doesn't start then compression or timing is off check your fly wheel and cam mark to make sure

if it start but doesn't stay running clean carb and check air way to the air filter
