Hi Chilli Red, and a big warm welcome to the forum.

I hope that we may be able to help you with any probs you have, because we all love to learn new things and tinker here.
We also love to see pics of your projects, as you go along.
Re: the McCulloch manual; I have checked the parts and manuals area and I can't see one for that model, however if Bruce can locate one, I am sure he will upload it shortly.
Once again Chilli,
