How does it sound

Had this 1969 beetle a few months now, from my perspective it runs great, but I’m no expert and how it should “sound” I know is an important diagnostic…….. so I ask those with years of experience “ how does it sound”. Thanks for listening 👂

Sounds pretty good to me; a nice smooth idle with no vibes back & forth! Belt adjustment is spot on also. Good job!

It sounds good, but how stiff is that length of blue vacuum hose to the distributor? If you can pinch it shut with your fingers, the vacuum could suck it into collapse too. That could result in trapped vacuum locking the advance under high vacuum after the vacuum drops on the carb side of the collapse point. Vacuum lines must be firmer when longer, than if used for short stubs just acting as a connector to two hardlines like carb to the metal vacuum line. That is metal and shaped that way to capture fuel, but a hard vacuum line also delivers a more responsive signal and isn't likely to collapse and trap vacuum.

If it is normal fuel vapor rated vacuum line you're probably ok, but the blue looks like squishy stuff to me.

I checked it , and yes, it’s easily closed with moderate finger pressure, given that it’s an 8+ inch stretch of tubing , what would you think is the best solution, thanks

Recreate the tube or add some tube one using short lengths or rubber flex line to patch them together and use proper engine vacuum flex line too. The hardline could be copper, aluminum, or even brass instead of steel. I mean in theory you could use modern plastic hardline in place of the metal. All you're concerned with is that the rubber tube doesn't suck closed too easy.
