Hi all, quick update.

I finally managed to get an hour to myself and investigate the carburetor issues. The throttle spindle was still very stiff so I removed the carburetor and took the throttle apart, it was difficult to slide the throttle spindle out, it appeared to have partially seized. With a bit of persuasion and some penetrating fluid it all came apart. With all parts cleaned up and well oiled the carb was reassembled and the throttle butterfly now snaps shut with no resistance.

The engine now idles at the correct speed and the throttle can be opened without the worry of the engine running away.

I'm still not sure what was causing the throttle to be so stiff, corrosion between the throttle shaft and the carb body maybe?
