Engine Noise

[STP]

Tell me if this sounds normal. It's a 2056 with a Raby carb cam and dual Dellorto 40s.

I keep thinking I'm hearing a knock.

It's hard to say. There seems to be an odd sound right when you open the throttle, but you saying you hear a knock might have biased my judgment. Also, cheap PC speakers are no comparison to being there.

You can use a length of rubber hose to listen to the engine. Just like a stethoscope
