| Well after much trial and error i have fixed the pinging prob. I threw a C8HSA plug in and no difference. I then put the standard key in and it was still pinging. It sounded like it was leaning out at high revs but no matter how far i wound out the H needle it was still pinging. So i pulled down the Walbro rep and gave her a clean but still pinging.
So i pulled the top chamber off and noticed the lever that holds the needle and seat where the diaphram pushes on looked a little low. So i bent the lever up a little and NO MORE PINGING!!!!! So it was obviously not getting enough fuel into the upper chamber.
I put the 5 deg timing key back in and still no pinging but heaps more torque. A mate from work reckons he can get me some AV gas, so i'll try some of that just out of curiosity and i may be able to run a full 10 deg timing key.
Now to fix the dodgy clutch......
