hi there. Qualcast have a basic manual on the following web address in the uk
http://www.qualcast.co.uk/manuals/classicpetrol35s2.pdf
..but maybe you had already found that. I do have an older set of "operating instructions" for the 30s/35s/ and 43s with extensive parts lists with numbers L22506 etc, but I wonder if they would be much use today... I bought my suffolk Punch in 1996 and it was second hand then. If you like I can scan the 15 pages and email them to you.
