Wow, that is a gorgeous car but a very expensive toy! My Malvern cost a lot less!
It's ok, we can still talk, after all, I may need well more advice! :)

I did warn you I'd need more advice....I'm wondering whether or not I'll need a whole new exhaust to make it more free flowing to compliment the
larger carb & manifolds.......

Like I said, it never ends ;) You are spot on, the Minor pea shooter will restrict your engine :( Luckily mine fell to bits just after I fitted the new head and carb :D
I got the 1 1/2" twin box 'sports' system from David Manners, easy to fit and well made but I did have to modify the down pipe to fit the manifold I had as there isn't a pipe available to match up. There is one to fit the Marina exhaust manifold but that manifold would need the inlet and exhaust sides separating so you can fit your alloy inlet - or you could plumb for the LCB which will go straight on.
If you are planning any future mods (new cam and headwork) then you might want to consider going to an 1 3/4" bore system to get the best out of the engine.

Oh dear, oh dear...I got carried away again & the wallet slipped! :oops:

I am fitting a complete Manners Group big bore exhaust system tomorrow, alongside my s/h inlet manifold & HIF 44 with Pipercross air filter! :o

Here's another one for you Panky...I neglected to look into how to connect my brake servo hose to the inlet manifold.
On your other thread Panky, you appear to have run a Tee from something but I can not really tell...any hints? :?

Andy.

You have been busy, sorry ;)
The threaded hole in the manifold is the servo take off. It usually takes a banjo bolt and pipe but I can only find the pipe

The other alternative is this but check with them to make sure it's the same thread - it should be the manifold is one of theirs :D

I have now ordered the Mini-Spares adaptor for my brake servo. Thanks for the link Panky,
You are going to regret replying to this thread almost as much as I regret starting it...........Today I fitted the whole new system (using a temporary
fix for the servo take off) so now have...
Manners Group big bore exhaust manifold & system
Mini Spares inlet manifold with HIF44 carb
Piper cross air filter.

It took me an age to remove all the old stuff (those one-piece pipes are a total bar steward), get it running & then get it running well.
I had it on the driveway running for ages, did several roll downs & drive ups the driveway & it sounded good, felt good, pulled good.
Drove 2 miles up the road thinking how good it all was then it promptly broke down! :shock: :shock: :shock:
Took me an age to get it running & nurse it home.....total loss of power! Fuel pump is delivering fine but no backfires so I think it's fuel starvation.
Tomorrow I will check for crap in the carb & then maybe try the mixture but right now....skint, tired, out of my depth & very pissed off! :(

I'd planned on being all done so that I could work on the Moss kit car tomorrow! :(

And it's all my fault WHAAAAAAAAAAA :oops: :(
If you haven't changed anything else then it must be the carb, was it going OK before it conked?

The car was running fine with the old carb & manifolds, etc.

It ran fine with the new stuff for a couple of miles......really hoping it's just crap in the carb!

I hope so too, but also check you haven't disturbed anything else, like wires on the coil - took me a while to find that I'd pulled out a bullet connector on the wire to the electronic coil when it wouldn't run :roll:

Aha! That's just the sort of thing I am always doing...why make life easy on yourself when you don't have to!!!??? :? :? :?

Removed carb & took off float bowl...what did I find?.....that orange silicone (& copper?) gasket goo!...all liquifying & disolving-like! :shock:
Lovely stuff tho't is, I've used it myself....but not on anything petrol related! The (still present) rubber gasket had obviously ceased to be useful & someone had bodged it.
The strange thing is that the carb arrived clean, with new manifold spacer & gaskets & an unused mounting plate!

Cleaned out carb, compressed air blow gun thru relevant bits & it's all back together & running fine....on the driveway at least....fingers crossed for test drive later!

Rubber gasket ordered & temp. fix with a nuclear proof sealant!

Phew! :)

Update.......(cue groans! :roll: )

The car runs & pulls well BUT bogs down if I am quick footed. :shock: No backfires. Is that lean, rich or something else? :?
Is it true that the mixture adjustment on the HIF44 only adjusts the idle mixture & that the rest is done to the needle size?
My carb being from a 1275 should surely have the correct needle & jet...............

That's correct, remember you screw the adjuster in to richen the mixture on a 44. You could try loosening the needle carrier and pushing it further into the piston a bit to see if that works. I had a similar problem with the SU conversion on my camper, I solved it by filing a tiny flat right up at the thickest part of the needle to make it a bit richer at very small openings.
Did you make a note of the number on the needle by any chance?
