There should be a little bit of sideways play in a Magnum Clutch. Depending on which way it's been mounted they MAY have forgotten a washer.

If it's popping and banging when you've revved it, that's also fine. You should be more worried about it if it doesn't...

What you should be hearing when it's warmed up, on the ground and ready to go out is an intermittent metallic pinging sound which indicates the clutch is just about at the engagement RPM. If it's constant you'll need to turn the idle screw on the carb to reduce the RPM.

Good to hear that.

Used to be about 1800-2200 rpm on the floor to be pinging the clutch ready to go

The mag clutch does have a lot of side ways play to allow for the chain moving but you can add an extra washer between the clutch and engine to reduce this.
The Honda GX engine will always burp and fart after acceleration whether a clubman or SP engine

Remember that the kart will flex in the corner so some play will stop thr chain being stretched too much. We only ever used the single larger chamfered washer on the inside and there was play never had an issue with it
