Read our Ultrasonic Engineer's reply to the customer's query below.
Q: Will this carburettor cleaning solution damage neoprene seals, O rings etc? Is it totally safe to leave seals in place or is removal required prior to use?
A: Over the years many different materials have been used to make seals and gaskets in carburettors, and we cannot guarantee that our cleaning solutions are safe to use on all of them.
Generally, the rubber seals used are very robust to chemicals considering they spend their life in contact with petrol or petrol vapours.
In an ideal world, we would recommend fully stripping down a carburettor and removing all gaskets, seals, and diaphragms before ultrasonic cleaning, this will give you the best chance of removing contaminants and getting into all of the cavity’s, crevices, and component parts then replacing all seals and consumable parts with new.
