Cleaning the carb

[Jim bow]

Should I remove the carb in order to clean it? If so, how do I remove it?

I have loosened the collar, but the carb won't budge.

Gentle heat, some penetration oil and try to rotate it. It's a bit more difficult to clean it on the engine but it can happen. But it would be better to remove in order to clean also the corrosion that prevent you now from an easy removal.

Before applying any form of heat to your carb, please ensure that your carb has no plastic components that might be damaged & that there is no risk of igniting any pockets of fuel that might remain in the fuel tank, fuel pipe or the float bowl!

Also make sure that the float is completely removed..............They tend to break with heat.

Split and then useless for ever more.

And yes there is fuel residue no matter how dry looking. Be careful.

personally I would say, NEVER put any heat near a carb!

Loosen the clamp bolt and wrap the carb with a cloth, grip firmly and try to turn it left and right. It may be tight but should move. It is probably a little tight on the spigot.

1974, 40+ with Villiers carb ??

Not really necessary to remove it to clean it

Spin off the bowl c/w with float

Unscrew the top collar and lift out the piston and needle.

undo the retaining grub screw and remove the centre jet assembly but now be careful to swing the float arm aisde and recover the needle valve before it falls out and gets lost.

undo the fuel pipe union to access and clean the filter.

See the diagram on the SOS website to ensure correct reassembly

Vic is Correct.

Let us know how you go with it aye?

I'd still try and remove the carb from the stub.
NEVER NEVER NEVER use heat anywhere near anything that has fuel in it. (tends to make a mess of your hair and eyebrows not to mention potential explosions)

As long as the clamp is fully undone you can try to turn the whole carb left/right. Make no mistake, it will be stiff at first, but once you get it moving it'll come off.Use some penetrating fluid and let it soak in for a few minutes before you start.
The fuel banjo joint is often a source of blockage as there is a very small filter in there. Take this apart as well just to be sure.

ULTRASONIC CLEANER, must be one of the best ways to clean carbs, no matter how well you think you've cleaned them using solvents, cloths, brushes, scotchbrite and pieces of wire, the carb looks clean and perfect THEN a session in the ultrasonic cleaner and its increadable how much crap and crud comes out.

[Charles uk]

I use one all the time, excellent!

For real mucky, I use white spirit, but watch the temperature?

[Collector Inspector]

I have procrastinated in getting a cleaner.

Is this the type of thing?

Yup, that's the type, similar to the one I use, but make sure it's big enough as you may not always just use it for carbs.

[Charles uk]

Might be a little short of power, 30 watts a litre is a bit gentle.

[JERSEYMAN]

I have no idea of the wattage of mine I'll have to take a look, all I know is that it works well

[Jim bow]

Thanks, guys. Penetrating oil and a good strong grip got it to break free.
