550 F2 started!
« on: November 13, 2021, 09:32:00 PM »
Had a free afternoon so set about something stimulating to stay ahead of what’s happening on ‘Mejima’

Carbs off and fully stripped but not seen green residue before, it got brighter the older and drier it got…..how queer!

Opened up and no float retainers, so that’s the first blag/purchase request. Anybody got 4 they want to part with?

I’ll order a new main spring, as you can see, interesting alternative figment

The sonic cleaner is being wragged to death in the pantry and will probably be on most of tomorrow at this rate, there’s a fair bit to sort out! And clean!
It appears they’ve been opened before as there’s new screws on the top and bottom but no evidence of any internal intrusion. That being said there are various o rings in places they shouldn’t be in the spindles etc. just bobbing about not doing anything as they’re too big and just bob up and down the arms so someone’s faffed about.

I presume because I need four of the metal float retaining clips that live in the bowls they’re dearer than diamonds and rarer than hens teeth? Can anybody help?

Main jet clips were available on ebay from Holland and if not try sirius consolidated in canada, i have dealt with them for odd bits ans whilst website is clunky and 'orrible service is good.
O ring kits you get from Nurse Julie direct rather than ebay

Hardest part to find will be the small pin located between 2&3 that bottom of return spring goes to

The springs that sit on top of the main jet tower and spring the floats, ye rknow what I mean.

I've got good pins thanks Julie .. Probably the only, easy to remove bit of the whole operation tbh :)

Julie's sorted me out for o rings Bryan and if you mean the little barrel bit for the spring? Well funny thing that, ..........when splitting the carbs apart, not one but one good one and one mangled one fell out of a greasy dirty corner stuck together with a load of crap. Winner!

What's the best attack on the bowls and tops for shining them up? Polish or have plated? (if poss)
Talking of which, can you buy the gaskets for the tops on their own or only with a kit. Im going to use the original brass wear if it comes up ok but will need gaskets, presumably if not its going to be gasket paper/crunchy nut cornflakes packet and a sharp Stanley?

Solvol and elbow for shine, top gaskets rarely break and tend to be in sets tho i did see a lone one on ebay. I have a very oldparts book that shows individual O rings and gaskets,it may well be the one in Alladins cave as Ash had all my scans for his dropbox

Nice on mate, I thought so on the elbow bit :) I was enquiring on the gaskets as ones bound to fail or break in teh polishing process. Just pre empting a 'bugger' moment!

It appears that ebay is dry of them at the min but common Motor in the states do them at $8 each plus a billion quid customs clearance, but at least they're available. Be easier if there were a set over here but you an have it all. Meant to ask, where do I look for this code to identify which type they are< Im sure I've seen it on here somewhere, P something carbs or am I mad? Not really started to read up just going at a  bit of cleaning at the min but I'm sure there was a set to have and set not to have?   No?

The code is on the carb flange where it bolts to the bracket, i just googled 500 four main jet clips and went down the list and sirius came up with stainless ones about $38 a set of 4
Or ebay 113717285385 from holland £33 a set

Is this the pin that needs drilling out to remove the long balance bar? Once out, what would you replace it with, a rivet pin tapped in and filed flat?

Edit...... Found another 2 as well.
