It's not valve related. When it was run low on oil for hours it probably wore the cylinder and it now has a little bit of piston slap, causing the knock. That's what the knock sounds like to me anyways.

This would also be why it's burning oil, because the cylinder is worn.

@RockeyDA Well it's needs to be tuned at full throttle. Problem is when the engine is under load the governor lets in more air which will lean it a tad. The best method I've found is to turn your carb to factory specs, tweak it by feel (I struggle with this), and then check your spark plug after a hard run to see if you're running rich or lean.

Well if it's rich the plug will be wet and sooty. If it's lean the plug will be white and ashy looking. Ideal is somewhere in the middle lol.

Here's a link with a nice chart:

I think a tan colour indicates a nice clean burn. Black is rich, clean lean.
