SU Carburetor Woes

British Cars with SU Carburetors are alleged to be finicky

I don't know - i went for years without touching mine until they leaked fuel and air

So I sent them out to be bushed and rebuilt them

No issues

Well then I rebuilt the engine  - Yes lots of mods

Flowed Head, Manifold and Exhaust thanks to Sean Brown www.flowspeed.com

I believe I still need work on my rocker arm geometry - Winter Project or when I am bored or tomorrow

We did a lot of revised lightening/balancing of the reciprocating assembly (crank, flywheel, rods, pistons)  - the engine has no issue running 5000 rpm for extended periods. 60 miles for example

But I bolted my rebuilt carbs to this new motor -

Rich - even with the jets adjusted full up (H4 Carbs)

So started on leaner needles AO in my case -  the MGA lean needle

Better but not great

Asked the advice of an expert - someone who does this often

Removed the dashpots - Jets not even close to the bridge - We have a culprit

So I took out all my spare (junk) carb bodies and rebuilt the jet assemblies with parts at the lowest range of size to obtain the best result - I should have taken pictures - revised a few washer thicknesses to obtain exact match between (read sanded them on a surface plate)

Anyway - better - a little more tweaking but an overall better performance - leaner less loading on the plugs still with AO needles

I am working up to the In Car Video

Somewhere West of Laramie

It has been said that - LBC's are not good cross country vehicles.

And I agree that I have enjoyed the traditional sports car pass time -

The car seemed perfectly suited to drive from small midwest town to the next  - a real thrill and a chance to recover and walk around

But just like cross country on a motorcycle - a LBC can be a stunning way to see the West (USA)

The views are amazing - the air is  fresh - and the roads clear and the vista's large

Yes it can be uncomfortable, noisy  - but if every hour, you get out and stretch - take a few pictures
it can be more than fun

it may  even turn into an adventure -

I would have have been thrilled to drive this road in my twenties when the car was new to me - and it did feel like I was 20 yr old for a few hours

I am however recovering from the thought and action
