Bent the lever back to somewhere around halfway between the bottom of the metering chamber and the gasket face. Dried the plug, and disconnected the fuel line. Pulled it over, and it ran for about 45 seconds with no fuel line connected! Must of been a heap of fuel still in the crankcase from previous efforts smile
Started with 1 1/4 turns out on the low speed - ended up at about 1 3/4 turns and idling well. High speed is close to the same.

Grumpy - all after-event criticisms are welcome laugh I spent part of my youth cursing over Strombergs, SU's and even the odd Tillotson. Life is nothing if not a learning curve banghead

Thanks all for your input! Buy youse all a beer one day! cheers
