new whizzer controls

repop whizzer clutch/ clutch controls

I have two different whizzer engines one is WSE from a 2008 whizzer ambassador. The other is from an engine kit and I beleive is an NE5.

I am having trouble figuring out what type of clutch I have and what parts I will need if any from the kit engine.
I haven't got pictures of the clutch, but i do have pictures of the engines.
The WSE has no spring/ lever on the side valve cover:


The Kit engine has the spring and lever:


The WSE engine has a valve on the top of the engine:


Will I need to use the side cover from the kit engine to use the clutch in the kit?

So does that mean the one on the cylinder head closes on it's own?
It is my understanding the original whizzers used the side release so I may go with that unless the one on the head is a better set up.
I have a front brake though so I may need to get a second twist lever for the clutch because right now it uses one lever for compression release and the other for the clutch.
If I can use the cylinder head mounted one I can just go with the controls I have.

I've try to find a picture of the controls you are talking about without much luck, do you happen to a have a picture?
