View Full Version : Solvent for cleaning and soaking carb bits please

22-05-06, 02:34 PM
Got myself a Factorypro carb recal kit at the BMF, so I'll be dismantling my carbs. They need a good clean anyway as the bike had only done 1100 in four years before I got it.

Can anyone recommend a solvent to soak the carb bits in to clean all the gunk off.?

Incidentally the carb kit comes with 3 sets of jets, 2 needles and clips, plus new stainless bolts for the tops and bottoms of the carbs. 66. A dynojet set is about 80 isn't it, and I don't know if you get new screws or not.

Carb cleaner might be a good one to try. :wink:

:D :D Does what it says on the tin :D :D

Really looking for something to soak bits in too, as I imagine they'll be pretty manky.

Thanks :lol:

in my experience, carbs just really get dirty on the outside. The screws get pretty naffed up if you are not careful undong them, other than that, theres not a lot else that really screws up, unless you use crap petrol.

the jetsm needles etc are pretty good though, as the needles wear overtime. I use Wurth electrical contact cleaner. Its fantastic stuff. Carb cleaner is also good.

I filled an old ice cream tub (a oval smallish one) with the contents of a carb cleaner spray can and soaked carb bits. I believe you can buy all these wonderful solvents in 5 litre tins if you look in the right place (I haven't yet). Just make sure you've got the windows/doors open and scarper pronto if you feel slightly odd. :shock:

It's not dirt I'm worried about Viney but the deposit left by stale petrol that there is bound to be on my carbs. I;ve used carb cleaner that you add to petrol and that defo improved things, but a strip is required I reckon especially as I've got the new needle and jet kit.

Yeah I was gonna fill a glass jar with a tin of carb cleaner contents, but figured there had to be a cheaper easier way Chazzyb.

Hey Mate,

You can use acetone, it is a bit hard to get hold of in the UK but works well. Just don't put rubber seals in it. They will dry out and fall apart. :wink:

Isn't nail varnish remover sometimes acetone? or what about some paint thinners?

Caustic soda crystals is best, Just the cheap stuff from hardware shop, dont mix it too strong, but only on the brass, alloy tends to make a fizzy mess :shock:

I've had really good results with a hydrochloric acid based wheel cleaner - it really dissolves the gum and white crud well. Problem is it will also eat away at the alloy if left too long, so I use it fairly weak and make sure I rinse everything really thoroughly after using the stuff. I don't leave the alloy bits in for more than a minute or so at a time, but the brass bits can be soaked for a while longer.
I'm told that toilet duck ( also acid based) works well, but haven't tried this myself.
When I run out of this stuff I'm going to try brick cleaning acid from B&Q 'cos this is also based on hydrochloric acid.
Don't forget to wear goggles.

Thanks guys. So it appears there is no hard and fast solution. Plenty of ideas to try out though. :D
