Qualcast Classic Petrol 35s

Having enjoyed great success with the 1966 Webb Standard, it is time to reveal project #2. 
Now why didn't I find these earlier this year / last year during lock-down

So we have....

The fuel system is bone dry, it took quite some time to get any fuel to appear in the fuel pipe and the carb bowl remains dry. 
Weak spark - but at least there is a spark. 
It's shows a lot more corrosion / deterioration than the Webb and right now the resting screws are seized so I cannot release the cassette.

Seen as bad, but all doable

Seen as bad, but all doable including the corrosion etc around the cassette in your first image . As far as freeing steel to alloy fixings goes, Plus Gas is the preferred freeing liquid over any of the multi purpose maintenance sprays such as WD40. A home brew of brake/ATF with acetone is useful.

The " micro switch" is the "kill switch" that earths the ignition to stop the engine - always assuming that it runs !

So throttle cable is rusted

So throttle cable is rusted to its sleeve have spent afternoon working it back and forward and soaking it in pen oil. 
 

float is seized / rusted in place

soaking screws hourly in pen oil hoping I can liberate the cassette, I believe it is possible to remove the roller and get at the back of these. 
 

cannot release screws holding drive shaft in place 

so does the micro switch connect to anything on the throttle mechanism ( there is a curled wire hook sticking out ) or does it simply get pushed back and forward ( I really need to get to multimeter out and test its function) 

unlike the Webb this is  going to need more than 8hrs of effort ho ho ho

In last post I referred to

In last post I referred to "drive shaft" I actually meant "drive shaft cover".

also struggling with pull start cover apart from the two on top is there anything else I need to remove undo in order to release this ?

The curly bit of wire is

The curly bit of wire is "live" to the electronic ignition module (no points or condenser) and the mechanical throttle/governor linkage touches it when the throttle is moved to the stop position.

Ok so activities have halted

Ok so activities have halted momentarily as the controller of free thought decreed that we must visit other nations, lay on beaches and drink beer with unusual names.
