cheap ultrasonic cleaner

Well I got licorice allsorts for fathers day. 🤔

[Glenzil]

yes i did leave the enulsion tub inserted! well spotted. I had a go at getting one of them out and it was well and truly stuck, so its a job for another day, but definitely must come out and be cleaned before they go back together.

You need a bit of 4mm dowel and go in from the top. Place the dowel on the tube and tap it out.

[Glenzil]

Tubes are out now - bit of heat and some WD and a thin bit of dowel

I think I will just stick with using the dishwasher or if there really bad boiling them on the hob with a dishwasher tab as its not failed yet.

May have to try this!

You can always clean the dishwasher out afterwards 

[ManicGTI]

If the dishwashers working properly, it'll flush it all out!  Most of them are clogged with crap mind..

I repair commercial dishwashers for a living and I find a lot that are clogged with crap.

[Bryanj]

You really need to instruct the owners that dishwashers ain't toilets!!!

Just  to add my 3 cents. It is important to make sure thatt he internal passages are clear ESPECIALLY the idle circuit. Below is a description I posted a while ago of how I checked these were clear.

The idle circuit consists of 3 holes and the pilot jet.

hole 1 can be seen on the carb wall on the inlet side throat at 90 degrees from the top before the throttle slide, this actually joins in to the hole from the air screw by the way.

Hole 2 is a VERY small one at the base of the throat on the exhaust side at 180 degrees from the top just in front of the throttle slide. This is where the idle mixture is fed in to the cylinder.

Hole 3 is where the air bleed screw goes in.

At idle air is drawn from hole one and the air screw then adjusts the amount of incoming air, this is then mixed with fuel from the pilot jet To provide the idle mixture.

The resulting mixture then squirts out of the very small hole (hole 2) at the front of the throat in to the cylinder.

I found the best way to check for blockage in the whole pilot circuit is to remove the pilot jet and air screw and blow down the air screw hole and at the same time cover the pilot jet hole and the other 2 holes with some combination of fingers and thumbs. You can then lift a finger or thumb from each hole in turn and hear if you get air blowing through.

It's a bit like mastering playing the bagpipes but an effective way to check the circuit for blockage.

This may sound complicated but if you find the holes and study the plenum chamber in the base of the carb it's pretty obvious how it works.

Hope this helps fellow owners with idle/suspected blocked carb issues.

I must apologise for my lack of foresight in that I should have taken some pics whilst the carbs were off. If I take them off again in the near future I will post pics to show where the relevant holes are.

The mental image this has conjoured up has still got me chuckling...

As I was reading it, my brain was already thinking of bagpipes before you mentioned it.  Uncanny, or was it the haggis I had for breakfast?

[ManicGTI]

Thought i'd add that I ended up basic ally doing the above.  I simmered the carb bodies in a Dishwasher Tablet Stock for an hour or so (Missus loved that), then did the bagpipe routine through all the holes to work out what went where.

It seems to have done the job, I was about to send the carbs in for US but I'm inclined not too for the time being, bike now starts and runs.

  Saved some cash, then.
