Default OS 120 Surpass Pump Timing?

I bought an OS 120 Surpass pumped 4 stroke engine. The engine ended up needing a bearing so I tore it down to get the bearing out. I marked my timing mark but I ran into the dreaded stuck piston pin and had to soak it for a few days to get it out. I finally got the pin out after a lot of cursing and getting my blood pressure up . I just realized when I soaked the engine it erased my timing mark. Is there any easy way to get the right timing again?

The timing mark cannot be erased. It's a dot on the camshaft. When the piston is at Top Dead Center, the dot lines up with the camshaft. Here's a pic of that:
