Motorcycle Carb Cleaner ?

[snoozer]

OK people I need to source some chemical carb cleaner, I've used an Ultrasonic cleaner for a few years but always thought it lacking somewhat even using propa Carb cleaning additive to the mix as strong as 50/50 and temps from 50 to 80 deg.
I watched a guy on YouTube use an Aerosol cleaner and the carbs came up like knew but he won't divulge the name as he says it's not designed to clean carbs but does the job admirably and apparently it's very prone to causing skin/eye problems should you splash some in, He always has an eye wash handy.
Anyone come across something that fit the bill ?

Tried all sorts in the past, had a bank of carbs absolutely solid no joy until I bought the real thing. Just bought a 1llt and at 80deg in the ultrasonic everything came free.

Wurth gasket remover is meant to remove powder coat so it sounds like it may work.

What carbs are they? For example, ones that were fitted to the Yamaha RD 250/350 LC back in the day had a brass ball pressed into them, to clear that airway out many owners have found that you need to drill that ball out first.

I have some very rare FZR 400 SP carbs that got blocked with dissolved Petseal tank sealer, no amount of cleaning in the ultrasonic tank and with carb cleaner seemed to help!
Ruined the tank as well

Thin guitar string is good for reaming out the passageways in carbs. I normally spray them, use the wire to ensure the passageways are free and then put them in the warm ultrasonic bath. Ultrasonic is good but it doesn't work miracles, sometimes you need to get mechanical.

I had some "scrap" model aircraft engines - siezed and caked in years of baked on castor residue, couldn't even strip them down without breaking them, no solvents or ultrasonic touched them. Last resort was boiling them for an hour in a strong solution of water and clothes washing powder (Fairy non bio in this case ). That got them nice and clean and they all started up after rebuilding.

First thing I do when I buy a new trials bike
Strip em and Boil em up in a pan
Works a treat

My old boss used a mixture of diesel and paraffin to clean things. Cleaned things well. I left my chainsaw in his van one night, came back the following day spotless, stank though!
