Exhaust valve spring retainers

[I like karts]

On an 8hp flathead. Anyone know how to get these off? For some reason the intake spring just has a normal retainer, but the exhaust has some crazy weird one.

I know... I'll try to get some up tomorrow. And it's really hard to see unless you're REALLY close
