Today in the workshop .....

If they keep doing gas they'll be total mongs before long, another drain on the working tax payer.

Nitrous? I occasionally find the canisters, on some sites.

 

[Cato]

I'm using that at the recommended mix and it is turning the carbs dark grey.
I usually set it for 10 mins @70 deg.
What mix are you using?
What settings do you use?

It does depending on the zinc content in the alloy unfortunately. If it's not affecting the zinc then it's not removing the build up, there isn't a way round it due to the compaition required to do the work I'm told.

For anything that's on show I vapour blast them afterwards to get rid of the surface tarnish.

I regularly see people saying that their carbs come out clean and shiny.
That's why I was thinking I'm mixing it too strong.
The stuff I'm doing is garden equipment like saws and lawnmowers so I'm not worried about cosmetics as long as its clean.
The first customer job I did on a non working Stihl chainsaw paid for the cleaner so it was a good purchase.

An ultrasonic alone won't leave the outface shiny it just removes the fuel deposits. Vapour blasting, chemical polishing or the vibrating ceramic beads afterwards are what brings the surface up.

Which reminds me I really should do the xt carb!

The owner of the 3TA is a happy bunny now that he's got it back and has some decent riding weather.

After trying a few I use Ultrocarb now as it gives the best results on carbs and small parts without being so harsh that it or discolours affects the metals/alloys.

Demilneralised water supposedly helps as it improves the cavitation, but the main benefit I've noticed is that the solution lasts a couple of washes longer using that when compared to tap water. The makers reckon Ultrocarb is fine with tap water, but I take the belt and braces approach on that.

Link to UltroCarb.

Is the dulling of metal not simply that Ultrcarb is a caustic (alkali) agent. The SDS shows it to be two caustic agents and a surfactant.

Alkali's dull metal, especially aluminium, acids brighten metal.

It's partly that, but it has to be an alkaline cleaning agent to remove the fuel residue. The other issue is that the zinc content in the alloy tarnishes, and the zinc content varies between manufacturers.
If needed it's very easy to clean the surface back up for carbs or parts which are on show.

Contrary to popular belief and online BS there is no chemical which cleans what it needs to and leaves the surface shiny.

No way, they're going up chimneys like they should be!

Low vacuum across all 4 cylinders. That'll do it then.

Nothing a good splodge of bathroom sealant won't fix.

I think that snot glue around the vac take off shows it wouldn't be the first 'repair' attempt.

So that PITA Enfield job. They've ditched 1 & 2 the separate rectifier for the headlamp, and the main Reg Rec which was a silly way of wiring it by Enfield anyway. Then fitted the Boyer power box, but not connected the headlamp & switch wires.

So now I've got to undo everything and start again and make up the link lead/spur that they should have left in place.

Speaking of Triumph Twenty One, this was cheap. Good job I didn’t go.

Bonhams Cars : The David Plant Collection, 1959 Triumph 350cc Twenty-One Frame no. H7477 Engine no. 3TA H7477

Triumph re-entered the '350' class in 1957 with the introduction of the 'Twenty-One'. Its arrival ushering in Triumph's unitary construction era, the model took its name from the engine's approximate cubic capacity in inches. Readily distinguishable by its Shell Blue metallic finish and...

I know the Brit bike market is down, but that's crazy cheap.

Fluid change time in the ultrasonic cleaner. Maximum of five cleans, £50:00 in powder and demineralised water per refill.

View attachment 538038

You should see if there's a "Spotless Water" location nearby, as it's a much cheaper way of getting demineralised (RODI) water

Or water from a dehumidifier.

Or water from a dehumidifier.

or rain water caught in a plastic tub from plastic gutters, just not if the roof is tin sheets. not fully deironized < spell but almost there if just very slightly acidic.
