What's the best way to remove petrol gum / varnish etc from fuel taps and filters.. Obviously not soaking in petrol! Tom

You could try ethanol, available from hardware shops and fireplace suppliers. It's a good solvent for fuel! REgards, Mark

I just use the same detergent we use in the washing machine in some hot water.

Carb-cleaner aerosol spray.

Soaking in acetone works but it will dissolve a lot of plastic/rubber parts.

Don't underestimate how effective a cleaner hot, soapy water is.

Use one of the specialist cleaner and degreasers that are used to clean the petrol tank before sealing

My 2003 service manual states; compressed air to clean air filter and kerosene or diesel to clean non electrical or rubber parts.

Be careful how you scroll over that link----it does work, just mind the dashes at the front............I have one of these and they work a treat !!....OK, you don't have to go out and spend £100 + but there are several bike and car restorers out in the public domain who advertise their services with an Ultrasonic cleaner.........The best part is that it'll clean ALL jet holes no matter how small they are....I've done carbs for Puch Maxi and Honda PC50 with great success............There's also Soda Blasting for general cleaning of the body, slide, top etc....It's non-aggressive and is a one-time only process in which the Baking Soda crystals disperse in the air or can be washed away.....

Coca Cola and white vinegar are both good.

Why all these ‘snake oil’ remedies? CARB-CLEANER is the purpose-made product – cheap as chips – simple to use – readily available – every workshop should have a tin! Shame if you haven't! ;-)

Some of these snake oil remedies will actually be found inside a tin of Carb cleaner ;)

What type of oil do snakes use in the Winter ??--- Mono or Multi- ??.....I do use a carb cleaner but only to loosen up the crud before hitting it with those ultrasonic sound bubbles....

Seems now we’re going from snake oil power-hammers to crack a peanut!

I bought a Toyata Yaris VERY cheap (it had not turned a wheel for two years, but kept in a garage for two years until the dead owners estate was sorted.) It had a few tick over issues it over revved on starting and stalled when hot. Problems solved with £10s worth of mechanic in a tin spray through the air inlet whilst holding the butterfly open. Not have a problem since.

Carb cleaner, good stuff, not in everyone's shed?, Vinegar, coke, in most House's or cheap and handy from the local shop.

The thing with that varnish is, it can be very tenaceous. Sometimes it's just easier to replace the jet/filter than to clean it (especially with Enfield parts prices). I've seen me "boil in the bag" them in acetone in an ultrasonic before (So hot water in the ultrasonic then seal the parts in a bag containing your solvent) You place the bag into the water and run it. Easier, cheaper and safer than putting solvent in the ultrasonic.

Carb cleaner spray is often not man enough to shift that kind of varnish stuff. Often times not much is, even with ultrasonics and strong solvents. What WILL reliably shift it is MEK but it's increasingly hard to get hold of in any quantity.

MEK is also used for cleaning plastic fittings prior to welding with glue. It is available on Amazon UK

Well thanks for the suggestions but it turns out gunged up fuel lines / carb / filters isnt the problem after all.. i was expecting poor fuel flow when i drained the fuel tank but its fine so back to the drawing board! Further investigations required!! Tom
