Hi John

The number you quote ties up with a Jubilee De-Luxe, the Standard being a 375/43; the difference being thetickler lever on the De-luxe.

I can thoroughly recommend ultrasonic cleaning, having been involved in the design of such equipment for the last 20 years of my engineering career.

Vapour blasting can also give a very pleasant effect but does not get into all those inaccessible places you need to.

If the carb is fora Jubileethedetails are - Choke size 25/32"; Main jet - 130; Slide -375/3 1/2; Needle - .1065; Needle position - 3 and Pilot Jet - 25.

Hope this info is what you need.

The 170 Main jet is for the Navigator, with the Electra using a 190.

Regards

Derek

Hi Derek,

I agree on the ultrasonic cleaners, I bought one second hand that also has a heating feature. I am able to use water based cleaners & when I take the parts out, they are hot enough that the water evaporates in less than a minute, so no rust issues on steel parts!

I have been using a citric cleaner, what would yourecommend?

Thanks,

Skip Brolund

Hi Skip,

I can agree that a citric based cleaning solution is the green way to go.

To see a good report on the use of aqeous based cleaning with ultrasonics have a look at- www.pprc.org/pubs/techreviews/aqueous/aqtech.html

Thanks Derek!

I've had some measure of success with an 4 quart old pot and an electric hot plate and a 25/75 mix of el cheapo lemon juice and water and boiling the carb body/bodies for about a half hour. Rinse them off, blow dry with compressed air and then into my benchtop media blaster in which I'm using sodium bicarbonate (baking soda). Once done, it rinses off perfectly. I went to my local farm supply a while back and got a 25 kilo bag for $15.00! The results are very impressive, a beautiful satin finish. Eco friendly too. Hope this helps. -Bill

Yep - citric acid is nice and safe and if you buy it from the Chemist/Pharmacist you can drink the fluid afterwards!LOL!! It's used in homebrewing so if you find a shop (Few and far between these days, unlike the 1980s-90s when even DiY hardware shops had allthe makings!) get a packet from them - or from eBay. "Citric Acid BP" will also be great for descaling your kettle - much better than using poisonous chemicals! It also gets scale/chalk off your bath & kitchen taps so it's worth mixing up a solution to keep in a spray bottle. A nice, safe, mild acid worth bearing in mind for light metal cleaning. For heavy duty use on rusty steel you can use brick acid or walltile cleaner. (Usually phosphoric acid) For drain-cleaning use a cheap (40p for 2 litres) supermarket brand Cola! No - REALLY!My neighbour is a cleaning lady and uses it all the time!
