No start after carb synchronization. What happened?

I was just "plug" advice. More complicated advice involves proportional amounts of wine bottles...

So right... I was ready to pull off the carbs yet again! Mind you, I can now do it in 10 minutes, or so... and I don?t bend them anymore!

To prevent the carbs bending/jamming, loosen off the 2 outer inlet stubs a little before replacing the carbs. When you've got them on about 2/3, nip up the stub nuts. This helps getting them aligned a little better. May bugger up the step between stub and isolator plate a bit, but does the carbs a world of good.
Not really a wino, I'd prefer a case of beer.

I was looking at an old Triumph Trident T150 the other day. It has a nice big strong cast aluminium flange that the 3 carbs bolt onto. Looks like it wouldn't twist out of alignment if you ran over it with a bulldozer. It's a pity Laverda didn't do something similar. That thin steel spacer flange on the Dell triple carbs might be lighter, but it's pretty damn flimsy.
The Dells might be flimsily connected to each other but they are fairly well secured to the head which, after all, supports their weight..

Hmmm. Must be talking about 180s, reckon the 'spacer flange' and the lower bracket on my RGS' carbies are pretty sturdy.
Must be a 120 thing

Sorry sir, won't happen again (pig's arse it won't)
AfaIk, the Tribsa triple carbs are also suspended from the frame to keep them falling off the connecting hoses. The bracketry is great, in comparison, the Lav effort is pretty lousy. But, in typical Breganze fashion, they got around re-designing the brackets by also mounting the carbs on rubber hoses...
Clamp or flange fixing was just the "normal" thing to do at the time, think Triumph/BSA must have been one of the first to use rubber carb mounts on production bikes, very common on competition machines by then. Perhaps a measure to counter fuel frothing, as much as heat isolation.

I was going to say it but I thought it was too obvious
Brett said:Carlos good to hear the bike is up and running. guess you missed the point where I suggested plugs before Piet did. Though he put it oh so more elegantly
Anyways so tell us did you get the MOT sorted ???
We actually typed at the same time, your post wasn't there when I started my reply... but was, when I pressed enter.

Funny thing that, we have had dealers replace numerous components including ECU's, HP fuel pumps and so forth before they actually think to check the basic's ( well when we turn up to figure out why the thing has been off the road for weeks on end... ) finally get around to pulling the plugs ( or should I have said unscrewing and removing the spark plugs and inspecting them ) only to find that they are wet/sooty/fouled or what ever... they fit a new set of plugs after much debating about how would that cause this or that ( as there it seems a lot of out of work rocket scientists these days that are moonlighting in the motor trade as "technicians" ) ... and presto the thing then starts and runs fine... funny thing that. .......and the excuse for not checking is... but there were no fault codes telling them that the spark plugs were fouled !!!!!!!!!! hmmm makes you wonder hey.Dellortoman said:I was going to say it but I thought it was too obvious
Then the next battle which comes into the equation is about who is going to pay for all the time that they have spent (oops wasted ) diagnosing and all the parts fitted.
If its a retail repair the poor old punter... but if its a newbie under warranty they then expect us to pay... I think not.
Hence the reason why dealers charge so much these days as an hourly rate ( its to cover up for all the wasted hours )

We used to call it 'Osram's Law'.

Probably a DIY solution I saw, very well executed though, looked like a factory item. But surely the carbs were supported by the air cleaner connectors, so no big deal really.
Much the same problem with almost all rubber mounted carbs when the owners decide they must have open intakes of some sort...
