The Halfords cleaner is OK. Access to a compressor to blow out jets and galleries will help.

Never noticed any difference in any of the carb cleaner sprays. All with toluene work well. Never dared use brake cleaner which is more vicious.

 

Can of compressed air for cleaning keyboards and a length of 3mm diameter silicone tube.

 

Seafoam dissolves fuel varnish. Dismantle and scrape with wood like a chopstick. Not the tiny holes or jets.

 

If in a really bad state (ethanol phase separation yellow crud).

An ultrasonic bath and a new set of gaskets.

 

If water damaged corrosion white crusty powdered aluminium, new carb or fuel injection conversion.

As a petrol additive it will help stop carb freezing. As a cleaner sprayed down the air intake or onto top of open carb not so much as a dedicated cleaner spray like STP.

Redex does appear to help injectors on injection and diesel but these force fuel through with high pressure pump, rather than engine sucking.

 

What are the symptoms?

Air leak at carb base mounting gasket is most common problem, not the carb itself.

Try not to laugh at the cleaning solution. It bubbles up, which cleans.

Dishwasher tablet/powder to degrease.
