Yeehaaaaaaaa

she runs. Set them up roughly as advised by Dave at boggs and she runs:-) Cant get hold off Boggs at the mo Bank hols etc so thought I'd ask on
here if anyone else could help in the interim; Bit of a problem . flat spotting around 2000 to 2500 rpm when repeatedly revving. I need to have it
running reasonable to be able to drive it there in the next couple of weeks for the rolling road set up.
Advice given was open mixture screws3 full turns from closed
Disconnct vac advance
set ignition timing to 11 btdc ( done using Gunsons Tachostrobe
Any ideas or thoughts very much appreciated

Try lifting the needles up.either
move the circlip down a groove or
add a thin washer under each needle.

Hi, what jet size are you using, I ended up at 1.55mm on mine, I would have a little more advance, I've got 14 I think at idle, Have you tried
blocking up the air correctors, hang I think I got a picture of when David did mine, different carbs but could give you an idea of what to do, he used
small bits of that ali welding rod, with a bit of a taper on one end and lightly tapped in and tested, if improves tapped in fully.
Before
After
Cheers

Just had a nosey in your archive and the carbs do look significantly different so may not be able to to the air corrector thing but David will be able
to give you council on this when you get over there.
The bits of silicone hose joining the manifold and the carbs be careful as I've heard that due to the vacuum created this can cause the pipes to
eventually come loose and come off, I personally would get some inlet rubbers off the bay for this purpose, don't wish to teach you to suck eggs
or anything but maybe something you hadn't thought of that's all.
Cheers
