No dis-respect intended here, but I'm with Andrew on this one.
Carb design is a hugely complicated, expensive and time consuming project (even in our days with computer aided design) There is a stack of variables that need to be balanced. Designers typically have first degrees in fluid mechanics and are armed with archives of experience, and simulation results.
Although I can see that filling will indeed reduce AFR, I doubt very much that the filling process takes into consideration the balance of other side effects.
Changing a jet for a properly designed and manufactured one for that specific purpose ensures that you are getting a properly designed product that will deliver a metered amount of fuel according to the throttle position...and not just a hobbyists nearest guess.
If distance is a problem, perhaps you could get remote advice on the right jet for you....mail order it and ask you local greasemonkey to fit it?
I know you will get the boost you are looking for one way or the other though...good luck and nice one for keeping us posted on the developments

I'm going to be getting a standard hitachi and inlet from a yard this weekend and am going to leave the custom inlet and su carb,
I think i'm going to save a bit of money and drive it down to lincoln and get that guy who you say bob to do it. I know that there is not many people who specialise in SU's any more and i think the place where i took it to were not up to the task.
Would you be able to come along too if i do go bob as your the one who knows how it all works, wont be for a few weeks or maybe even a month?

if you tranfer all you inlet and carb back to standard for now,and when the time comes around for us to go to lincoln,he can do mine 1st on the rollers while you are changing yours back over to the su setup...Does that sound ok
