This is how my right hand one is connected to the actuator arm.

Thx. for the clarification.

Hi, yes starts fine on full choke and as soon as it fires runs smoothly on around 1/3 choke.

Nigel

Thank you Nigel

I think you probably could, although there is the return spring that bears on the actuating arm and getting that back into position in situ might be tricky.

much appreciated Wilf

Just a thought Maverick, my Stag always started like yours, lumpy for the first few moments, but then ran perfectly. Having done all the other jobs I decided to stop the slght weep of coolant from the outside of the right hand head. I added Steel Seal to the coolant and to my surprise not only has the external leak stopped but so has the fluffing on startup, leading me to believe that I must have had a slight leak into 1 or 2 cylinders. As I said 'just a thought'
Cheers Mac

A small breach into the cylinder can cause a lumpy start that then clears. Check by pressure testing the cooling system. The testing kit is available for <£50.
Also do a compression test.
no amount of fuel system or ignition system tweaks can fix those two issues.
