I have pretty well solved the tuning problem - I have one of those spring loaded mixture adjusters - but the knob was just turning on itself - the actual adjusting screw was not moving. Once I took it off and stuck my allen key down the hole I could feel it move. It was about 1 turn too rich - it suddenly hit a sweet spot , and whang!. Slight tuning issue to sort - hesitant coming on to throttle - feels like a lean spot. Will have to look further.
My AFR system arrived today (about 3-4 weeks). Am trying to get some work done tomorrow, having killed all today.
Brian, I think I posted pics of my piston in progress - compared to the damaged one. Fat chance of buying one here - and I really just wanted to know if it was the problem, before scouring the world and spending mega$'s. This one cost me about half a day and $2. And seems to work. I'd still be waiting after Xmas for the answer. A small workshop lathe is the best tool you can buy.
