Thanks for the links! If I have to have the manifold off I'll definitely give those a try.I used this stuff I borrowed it from someone on the Forum
The throttle seals I think I got from here:
I don't have the kit to go that far so thought it best to leave it. I've had it off and cleaned up and now it idles around 1100-1050, so some improvement.One of the last things to do idle wise it to put a bit more preload on the spring in the idle valve, but it's a bit of a job.
You need to dig out all the epoxy, it reveals a bit flat head grub screw. 1 turn on this or so to account for any yielding in the spring over the years. Then you should be able to use the other screw to adjust idle again.
Here is a pic from SAU.
I think I can live with that for now so I'll leave it as is. At least until after I've been to some shows this year - that's quite enough time in pieces!
