Tom, thank you - it's a 30 - was just playing with it
And connected the gav before tightening the carb
And now she fits! Guess there is enough play between
The wiggle room in the firewall hole and the carb mount
To make it work.
She started great but haven't been able to road test it as its dark here.
The gav is quite a bit stiffer than my old one - how stiff should it be?
Thanks
