Can’t make out 502 mpi timing marks.
 

Anyone have a picture of a new balancer so I can see what the marks are. I can’t make these out.

Look for timing tab basically off of timing cover.

I only have a pointer

I think the little white mark, and the scratched off paint, represents 8 degrees. I think I can see a zero at the next mark past it, indicating 10. I added some markings to your pic to show you what I think I'm seeing.

ok, if that’s the case, I’m right about 8-9 degrees then

Could also use an adjustable timing gun or measure diameter snd do math :)

that deep groove is tdc use an advancing timing light

And the line scribed in closer to the bottom, that is not as deep, is done at merc for timing at full advance. It would mark 32* in most cases.

nevermind

hy...can i ask you what is the distance from your tdc on your pully to your 10 degree...i yust want to check..my is 0.6 inc..tnx

Don't trust anything, get a piston stop and make sure it's right. If you are running a multi-spark ignition, you will need to disable it to check the timing correctly with most advance retard timing lights. My brother bought a boat and trusted the timing marks and detonated both motors.

Agree, first find your diameter and buy a new timing tape - they are cheap and will most likely fall off sooner rather than later, but will give you a good idea
Next you find TDC using the stop method me too ed above and place your tape accordingly

That line is TDC. You won’t need a timing tape if you get an adjustable timing light.

Very true, just about any auto store stocks a digital timing light and they are cheap enough
