G'day all,
             Ebsbury, great link, thanks. Very useful.
Back to Hubie, closing the choke makes it worse so that means the main jet is too rich.
I run a 930 on the '51 A7 with no air filter and straight through pipes and am pretty sure it has a 160 main, 25 pilot, 106 needle jet, #3 slide, clip in bottom groove. I know an A10 with a 928 will be different but think a 210 main will be rich.
Just my thoughts.
Cheers

Hi all,

Drilled out the original 170 jet to a size noticeably larger than the 210 I replaced it with and it goes much much better.

Cheers,

Hubie.

I'm running a 230, #3 slide, .106 needle jet and needle in the top slot on my Flash with a 928.
