Dont force anything!
I've not read dans guide so I dont know if this is included, but for me, I find it easier to remove the max fuel screw, and hold the stop lever to the stop position, get a screwdriver underneith the lid and push the throttle paddle back towards nearside of car (the part the gov clips into). After some fiddling and swearing, make sure the cradle is past the stop lever to clear everything, I would then tap the main throttle shaft through the body using the allen key used to undo the lid. Lid off. Done it so many times it takes about 2 seconds now but its real fiddly to begin with.
One more thing, make sure you wipe clean the seals, else you have it all to pull apart agian!
