With both carbs assembled but not setup, I've decided to get a service kit and replace the Waxstat jet with the new type after reading about the pros of not having a lump of wax which determines the fuel mix when hot.
All linkage, pipes and fixing are now cleaned and painted as required. New fuel lines and filter to buy.

This is my record of the restoration of my 1977 Triumph TR7, I bought the car in 1983 for £1500. Over the four years of driving it I had got married, moved to a 110 year old cottage in need of renovation and given a new company car. The TR was parked in the garage (1987) at the end of the garden. I always joked saying "that one day I put it back on the road". Twenty-four years later (Nov 2011) that day has arrived - wish me luck.

Black and white...
You can easily see the difference with first carb reassembled - second carb now stripped and in the cleaner doing its stuff...

Ten pounds well spent!...
Turns out that the suspect ultrasonic cleaner wasn't Fairy Liquid after all – couple of hours in the cleaner at 45-50° heat did the job.
The body of the carb took the longest, after about hour I removed it and using a nylon brush I loosen some of the stubborn bits.
The heat makes a vast difference, previously I've allowed the fluid to heat itself i.e. the ultrasonic action would heat it but not to a high temperature.
Looking good - now for the other one.

Carburettor strip and clean...
With the inlet manifold nice and clean, time to tackle the carbs - twin SUs covered in thirty-six years of crap and grime.
Decided to get some "special" ultrasonic cleaner, 1ltr concentrated engine component formula - wasn't sure if I had just paid £10 for a litre of water and washing up liquid!
I started by taking these photos to remind me how they should look when putting back together – I have a pdf version of the workshop manual (on my useful links page), so print off the carb section pages and put them in a clear page file which I had already done for the engine rebuild.
I split the carbs and thought doing one at a time was a good idea, putting them into two containers marked left and right.
With the first one stripped off to the cleaner and the Fairy Liquid!

Engine breakdown... pt9
The oil pick-up pipe and strainer was full of the thick sludge oil from the sump.
I've order a 2 litre Ultrasonic cleaner which I'm hoping will help with all this cleaning especially the SU carbs when I get on to them.
Two bolt remove and lifted it off, yet another gasket to scrape off.
