How big is the 2060 sprocket?   How many teeth?

You can use a single pitch sprocket (60) for double pitch chain (2060) as long as the sprocket isn’t too small.       If the sprocket is too small the angle of the chain on the sprocket gets too sharp and the sprocket won’t let go of the chain smoothly.  

Google AI suggests that 30 teeth (single pitch) is kind of the tipping point on big enough to not wrap at the release point.
