Thanks beelzebum. Starting from the gap/notch clockwise looking from the back pin 1-8 (for octal) is right yes?.

My input jack is connected to pin 2 V1 with the 68k resistor and a shielded ground cable connected one end as per instructions. V1 is not earthed though. I am following layout diagram for two stroke here http://www.tonecentral.net/gearpics/homebrew/twostroke/Hunter_Two_Stroke_Layout-180.JPG and following the book. As well as occasionally checking with the weber Maggie layout too.
