Meant to say that there is a noticeable misfire/cough when I increase revs, timing using a strobe seems fine.
When you increase the revs can you see the timing mark moving and giving more advance?

used the lifting pins to raise the pistons right up
Only lift the piston 2mm or so. As I said are you sure both carbs are set the same including the butterflies. As Pete said on tick over check the air pistons are the same height ie gap between the piston and bridge.
Good luck

Needles sticking and need centralising? With the damper plunger removed does the air piston drop easily with a clonk on the bridge?
Are both needles adjusted the same?

Over the last 18 months the car has moved very little, the last time fresh fuel was added was early 2023, is it possible the problem is due to fuel that has become stale?
Could be stale fuel, do you use E5 or E10? The more ethanol the more moisture it attracts.

Also make sure you have enough damper oil. I use 20/50 engine oil and top up to half way up the filler. Don't overfill.
Check for air leaks. My car used to stall if the mixture was too lean.
Check there is slack in the throttle cable at idle and the throttles are returning to the stop screws not held on a short cable. I've done that!

It is if you live in London, even 30mph can get you fined! Going from 70 to 30 down the A13 will get you run over by dirt or scrap trucks.
Welcome to my world....

Frontline T9 or Vitesse Mazda box they are both around £3500. I would ask BGH Geartech who specialise in T9s if they could help with a gearbox and then perhaps get your adaptor plate made. Still not going to be cheap but BGH will make a box to take 250bhp!

It was stronger and of course effectively had overdrive but again the ratios available werent great.
The ratios on a 2.8 litre T9 gb are almost exactly the same as the Triumph. The four pot 1.6 litre T9 has different ratios with much shorter 1st gear so not suited unless you want black line starts!

We had a vicar who visited our school trying to teach us RE. He had a blue Vitesse convertible which I thought looked and sounded great. It would have been around 1966-7 and it must have influenced me as I've had three Triumphs a Spitfire, TR3A and Vitesse.
My chemistry teacher had a Vauxhall Ventura that he used to bomb around in.

It's not ideal to use the throttle cable to adjust the idle but for now drive and enjoy. As the engine bay gets hotter the idle will drop 'cos the cable will lengthen😂. Sorting out the cable then tuning the carbs can wait for another (warmer) day.

Select an O-ring that is just a tightish fit on the cover stud - not too tight! Push that down to the cover, then a washer, finally the nut.
Thanks John, at the moment I have a tight fitting 3mm thick rubber washer then steel washer and nut. I'll try an O ring as the above doesn't work. Perhaps the rubber washer I'm using is too stiff and not sealing. I have some O ring but fresh out of tap washers!

My cover weeps from the studs. I've tried sealing with various washers but oil probably in the form of vapour seems to escape and dribble down all three studs. I give it!

only your employer had made you do that, you'd be eligible for a huge claim by now...
I had one of those water roller trays for envelopes but yes still licked the stamps. At the end of the month when invoices sent out it did leave a sticky tongue. The good old days decades before internet and no fee no win legal aid!

Ahhh you owners who start fiddling with Triumphs perfect design😲
In my defense Your Honor I bought it like it🙈🙉🙊. I'm just trying to make it all work properly.......well mostly as I do love fiddlin'
The words Triumph and perfect design shouldn't be used in the same sentence.

I'll check but from memory its more of a problem of bellhouse to gb cover clearance. I have the cover higher on 12mm foam but it still nearly touches the bellhousing. This may be due to my T9 gb rear mount altering the angle of the engine/gb. Moving the engine back 6-8mm will give more rad fan clearance but results in another problem!
-
Swapping left to right pushes the engine further forward. Not what I wanted. I'm sure I tried it when refitting the engine. I could fit the rubber mount to the rear of the turret bracket but I didn't think that was as wsm. I don't have mount shims on the nearside and the sump is might close to the rack. I have two shims on the driver side with much better clearance. Another job on the list.
Related to this I spoke to Superflex and ordered diff mounts and they are trialling poly engine mounts with a soft as original 60 Shure hardness. They won't be cheap!

so which way round the mount brackets are attached to the block....
Now there's a thought. My engine is compared to others too far forward. I'll check my brackets to see how I've fitted them.

, best thing I’ve ever learned for making the engine more performant is doing the timing by feel and road test!
Yes the WSM is a starting point only. Keep using if possible the same grade of fuel and listen and test.

Are there any 'plug and play' carbs that would give me, say, 20-30 more bhp?
For normal driving it's not bhp you need it's torque. Perhaps look at a camshaft spec and talk to Newman Cams as they are very helpful or Chris Witor. However you will open Pandora's box then look at distributor/electronic and the nightmare of carburetor needles/damper oil/spring rate. I know this as I've been through the pain. First off check your cylinder compressions are equal and correct or it's all a waste of money.

UK; the officially-run central-testing-station system was introduced many years ago to allegedly prevent paramilitaries and other criminals from running MOT scams. Strange that this is the only region of the UK that has criminals who may want to fake MOTs...
Barmy, I hope common sense soon prevails.

You now have a working Assembly! It'll be fine just give it a few years/decades........
In reality I sympathise, what a barmy system. However I can see a business opportunity aka your chance to make £millions!
