Carby cleaning methods

[dom14]

Hi Guys,
I'm after some ideas on how to clean the(interiors & microscpic vents for the most part) of a carburetor.

Basically, I'm after either,

1) No rush, dipping method that I can leave over night or

2)Quick method like blasting, boiling, etc with some sort of chemical, etc.

Since I haven't done it using an effective backyard method, I would appreciate some known, working methods.

Basically, I'm interested in non-sophisticated(no pro machines) method to unblock and clean, possibly blocked fuel lines, etc.

Thanks in advance for any help & ideas.

IMO You really need to strip a carby right down to clean them properly (if you haven't already), sometimes a small foreign body can block a jet or small hole, and no amount of cleaning will get rid of it without removing the jet, then it just needs a good blow or a little poke (don't we all, lol)

I just used to strip the carby down as much as possible, soak parts in petrol, scrub with a tooth brush (someone else's, lol), then rinse in petrol again, then repeat with a spray can of carby cleaner and a paint brush, then blow off with compressed air.


Carby cleaner is really the key cleaner, the petrol just removes the bulk of the crud and is cheaper than carby cleaner (well used to be when I played with carby's, not so sure these days)


Many times you may find you also need to replace gaskets or seals etc, often new gaskets/seal can end up being the fix to the carby problem (if it has one) anyway, id suggest you check to see if a kit is available before removing/dismantling the carby, often old gaskets can tear easy on separation ,and without a replacement gasket on hand, you are left walking.:tongue:

Yeah, a replacement kit is available for this. I already bought it last year and 'rebuilt' it. But, I did a dodgy job. I think that's the reason the problem might have come back at me.
The kit is not cheap, so buying another kit for the sake of getting couple of new gaskets sounds like bit too much. So, I decided to cut the gaskets with gasket paper.
It's a fun exercise, but takes time and patience. :animierte-smilies-t
Base gasket is easy to cut, but the others are bit handful.
Since, I stripped the carby down to pieces, I want to make sure I do a good job this time, so I'm taking the time.

I read somewhere I can boil the pieces in a chemical bath, but I'm not too sure what chemical to use.

Thanks mate.

Dom i remember you doing your carby.

Did you get an original needle and seat
You might be able to get away with reusing your old seal

What is it doing this time?

Hi mate,
Yes, I'm doing the carby again and just finished it. It was stalling, not starting and cutting off on both gas and petrol(started with LPG).

I did the carby a thorough cleaning job this time. Needle and seat was from the rebuild kit. I didn't change it this time, 'cos it's just over a year.

Now, it's running ok on petrol, but won't budge on gas. I'm opening another thread to discuss it.

Thanks mate.
