Oh I see, perfect! So what you are actually doing is lifting it up, not pushing it forward. That makes perfect sense now. I was also confused about why that pin was just allowed to flop around in there and was looking for a socket for it to fit into to hold it up and couldn't see how it had anything to do with cold starts.
That manual certainly is not very clear.
It looks like I am going to have to add another gasket
to the shims as well.
It's a difficult thing to work on, as you can't really see in there to see how things work.
Somehow something has changed with the shutdown mechanism too. I now have to fiddle with the cable before I can restart the engine. It's not the cable adjustment though, the problem seems to be inside. I can shutdown by working the lever by hand and it still doesn't reset properly.
Anyway, hopefully I can get this sorted out this week.
Thanks very much for your help.
