Another thing to check out is soda blasting.

Hello Lynn,

Soda blasting! I had forgotten all about that option. I went online and found this video from Supercheap Auto ... Accessed 2nd September 2022 from, https://www.supercheapauto.com.au/p/...kg/348346.html

A bit more digging then I found this link of bulk Sodium Bicarbonate Suppliers Australia https://www.australianchemicalsuppli...um-bicarbonate

Thank you for the reminder Lynn.

Kind regards
Lionel

I purchased a ultrasonic cleaner off evilbay. it done a good job with no damage. It depends on what type of cleaning agent you put in to what job it does. I just used parts cleaner fluid diluted and put the carb in and it came out clean. I did use a toothbrush in a few spots

Hello Paul,

Thank you for your reply - it is much appreciated.

What brand and size ultrasonic cleaner did you buy? What make and year of manufacture carburettor did you use in the ultrasonic cleaner?

Was the size big enough to do the job - or with the benefit of hindsight would you buy a bigger or smaller unit? Or were you happy with the size you bought?

Last of the string of questions, Paul - what brand of parts cleaner did you use and what dilution?

Sorry, it took so long to thank you and post a reply.

Kind regards
Lioel

....is getting into the tiny many passage ways and jets that can be damaged by forcing steel wire to unplug them. Varnish and grit glued to varnish is the real culprit...... Today the real strong stinky carb cleaner solution is no longer available..... and you think acetone is bad!!!!! It came in five gallon cans and was usually diluted with water......... carbs had to be rinsed with boiling water...air dried and passages blown open.....carbs could not be left for more than overnight or the metal could/would get pitted... gloves would not be used or were not readily available back then...... your jeans needed a good separate wash cycle if you spilled some and you always did....... usually used a deep fryer basket but every now and then one would fall to the bottom of the can.....dipping your hand left your skin tingling and youmade a run for the garden hose....

Old carbs...core..... were worth $10 to $15 each at carb cleaner shops......last Zenith I saved 50% of the cost by bringing in boxes of complete cores as trade.

Only one good shop I am aware of in Oshawa.... the Oaks brothers( moved from the old Weston shop area)...... they still use a "flow Bench" to test rebuilds and to do the set up of the jets....... kerosene and a huge dust collector system provides the vacuum for the flow bench. They recommend keeping the carb wet when you pick it up in a Zip lock plastic bag....installed on the engine and it started right away and only needed a 1/4 turn adjustment on the idle.

Ultrasonic dealers should be able to recommend what fluid mix to use as I would be afraid of acetone fumes unless outside.

Most of these jobs are better done on a sunny day outside the shop.....

Try burning off the lead deposit inside the exhaust manifold with an Oxy torch to free up the heat riser.......... working down wind..... white smoke past the second neighbor...... no mosquitoes for 4 hours.....

Jordan Baker as even been able to restore the fancy gold plating on his rebuilt carbs bodies/parts.....

Hello Bob,

Yes, most of the highly effective chemicals have been taken off the market. After they realised how hazardous they were - unfortunately.

I did a search on the internet and found a ultrasonic cleaner manufacturer who made some recommendations about what chemicals were safe to use within an ultrasonic cleaner to clean carburettors. They start off with this warning. On that Hanno might be able to confirm... 'Using the wrong cleaning solution can damage your carburetor'.

Only the Simple Green is available in Australia. From the big green hardware store that puts all the old local independent hardware stores out of business. You know that one!
