Hi Top Gun 777,

Now that's interesting.

I removed one shim (now have two on the button)

I'm running a No.5 plug (This is a hot plug, I think!)

I could not get the temp above 160 on a nice warm sunny day.

And I'm being told my piston looks like I'm still running rich.

If I go back to a 6, 7 or 8 will the temp not drop?


Many Thanks

Kevin
