Thanks for the reply, GM. I know you are not on-line at the moment.

I am having trouble getting hold of a 200c calc. carb. (it was a holiday this week end) so I haven't started the treatent yet. but I will post as soon as possible.

Also if anyone else has any ideas on this I would be grateful for the input.

Finally, GM said the info was 'scanty', what sort of info is required? What did I miss out? What would be helpful? ....

Thanks
