If it's the "Dellorto Book", all of the above. The book by Bob Fleming is much better, especially if your carbs have a bit of a cough.
I think somebody gave me a copy - it was disappointing for a book with "super performance" in the title. Basically nothing about tuning carbs at all, just a collection of dull info and some basic parts diagrams which are on the internet anyway. I just looked for it and can't find it - probably gave it to someone else.
I've run the lot through the ultrasonic cleaner with a specific carb cleaner and it's done alright: Bearing in mind I had degreased all this before, the water in the tank was filthy dirty. The carb and components are never going to look new by this method but at least I know its clean and I can examine the parts. These won't go again: The far left is bent for some reason. Also the hole has been manually elonagated. The other is normal:
Slightly out of sync, I forgot to mention that I didn't have a punch long enough to reach the bearings either end to knock them out. Instead I used a screw driver bit just big enough to sit on the inner race but small enough not to ding the I.D of the spindle hole in the body (if that makes sense) and a length of stainless steel left over from my homemade headlining bows for my beetle:
I've taken your advice and found a company in Malvern that can do this. In the meantime if anyone has good spares of the following parts let me know: 1 off: https://www.dellorto.co.uk/shop/del.../parts/drla-parts/drla-pump-diaphragm-spring/ 2 off: https://www.dellorto.co.uk/shop/del...arts/9926-dellorto-drla-dhla-air-bleed-screw/ 1 off: https://www.dellorto.co.uk/shop/del...to-drla-weber-idf-dncf-vacuum-take-off-union/ I know these are available from eurocarb but just in case I can recycle some parts sat idle on someone's shelf here. Happy to pay etc.
I'd be alarmed if it were anymore than that given how relatively small and clean they are. Shouldn't take him long (be back with me tomorrow).
I think he said in malvern he just charged by the hour/time. If you are happy I will take mine on your recommendation. I've a shed load of crap carbs to do... The only worry with vapour or ultrasonic was water is used. If its all removed and dried quick, corrosion won't be a concern. As you've seen it's a pain.
Eurocarb told me to get 28 vents. In the dell book it shows 32 vents are ideal, cb performance know what works from actual dyno testing so take your choice...
Anymore than that and I would have done them for postage for you . I’d ultrasonic them again and give them a good blow with compressed air . A light spray with WD40 stops them from corroding after .
...and Eurocarb is correct Bob Fleming's book is mislead...hurragh...mis-...hurraaaaaagh...misleading. Sorry, bit of a cough there.
If its for a high revving application then bigger vents. Easier to tune for a lower revving bus rather than Beetle application with smaller vents. You get a stronger vacuum signal at lower revs to operate the main jets, so you dont need to be so precise with the float level.
I went with a firm much closer to me in the end for £20. I'd used him last year to clean up my 67 Beetle petrol tank and he did a good.job of that but wasn't aware he he did vapour blast too until I called. The place in Malvern quoted me an hour but also said if it took 30 mins then he'd charge 30 mins so is still worth a look.
Yes I will do. I also plan on checking the base for flatness and if needed a couple of passes over a piece of glass with wet and dry so will no doubt need yet another cleaning!
