Lawrie,
Thanks for pointing that out. You are of course, quite correct and I am a
"silly old bugger", forgetting too much. I look at my chart and either
screw down the "mixture screw" or screw it up, what ever the chart says.
Thin air does require less fuel.
There are 2 other things I should have mentioned.
1) On my 746cc P-type (supercharged - running 7 : 1 compression & 10 lbs
bost) I use an HD6 carbie which is 1 3/4".
2) Whilst I use .100" needles, there is a far greater range in.090". Or at
least, there was, when I started that project.
Thank you for your interest.
Pip
