If you look carefully on the flywheel, you can see the TC 1-4 marks. Thay are very faint so take #1 spark plug out, put your thumb over the hole & hank crank until you find compression. Slowly bring the piston up to the top of its stroke; use a long screwdriver in the spark plug hole or piece of wire to indicate when the piston is at the top.
Those marks are VERY faint so get a good light & even use a small wire brush to clean the flywheel.
Timing by ear can bet somewhat close, but just remember that the important thing is to not have it timed BEFORE top dead center. That will cause the engine to try to run backwards especially when being hand cranked. Broken wrist anyone??
Don"t be lazy; do it right.
That is the old mechanic teacher in me talking.
