36mm DellOrto's on SFC1000/Corsa engine setup.

not much in that section, see: https://www.stein-dinse.biz/Moto-Guzzi/Vergaser-u-Luftfilter/Vergaser-komplett/Dellorto-Vergaser-PHM-38-BS1-L-Fl-Ch-04813::1075.html#prettyPhoto

Not sure what you mean.  The photos clearly show a totally different casting to the PHF with no provision for the inlet-side bracket holes.  The specs also show a 4mm larger inlet thread (which the Lav bracket has to fit over) - little wonder it was a bugger of a job for whoever did it.
The PHF 34 was absolutely no problem, nor would be the 36 from what I can tell.

Maybe I look at something different than you, but the only difference at the marked places (which is were the screws go in to fasten the back plate to the carbs) is that the outer diameter of the threat is larger and therefore the surface to the back plate is smaller and the screws may sit closer to the thread.

And that Lothar, is exactly what Steve mentioned, there is no provision for installation of the backing plate screws on the PHM range of carbs.  The new PHF castings are still very similar to what Laverda installed and can be retro-fitted with all the Lav paraphernalia as required.

In stock form, the plate is only just adequate, mod it to fit over the PHM mouths, it will be weakened even further.

I've built many generic PHF into triple banks, just gotta know wotcha doin'...

Thanks for all the replies. I am all for DellOrto carburettors. I know the modern Keihins and Mikunis are fast and all that, but I like DellOrto's.

So, I am trying to look up a set or make up a set of PHF36.

Therefore:

* what would be suitable of jetsizes, needles, slides, idlejet, etc for a set of 36 on a SFC1000 with mods I described in my first post?
I mean, What did Laverda supply it with on a SFC1000 delivered with 36mm DellOrtos?

* can a set of the older DellOrtos be used on my bike (the ones that came with big metal rings to fasten on to metal inlet tracts?
On my bike I long ago installed aluminium inlet tracts in 36mm and 36mm rubber inlettracts over those with two fasteners (Worm band) on each stud.
Or are the older version DellOrtos not usable on my engine setup?

Kind regards,
Jacques
