Charlie/others in the know
are the VHB29s a bolt on replacement for the SS1s on a V700? I assume
they will fit, but does the V700 'prefer' a different size jet or
different needle in the VHB29s? Just curious.

Bob,
Your "round slide" carbs are SS1 29s. My '69 Ambo came with them also
(as did most if not all of the first series Ambos). Most owners changed
them out for the VHB29s early on. Besides leaking, I don't think the
SS1s meter as well. The one on the Falcone leaks just a bit during
starting then stops, but cold or hot it sneezes, pops and hiccups at
various throttle settings.

From what I've read (Moto Guzzi Big Twins by Greg Field) and seen at
various meets, the Amals were installed on mid '73 production date
machines and most with the Amals also had four-leading-shoe front
brakes.

I have a set of each variation from the "norm" to play with if I ever
get tired of having carbs that work properly. Cheers,

Charlie

 SS carbs refers to the old round slide Dell'Orto carbs found on most
1950's and 1960's Italian bikes. All with seperate float bowls either
on the side or fully remote.
SS1 29 carbs were fitted to the first V7 twins made (first year
maybe???).

Then production went to the "square slide" VHB series carbs which have
the float bowl built into them.

Seems some loops came from the factory with round AMAL carbs at some
time also??? Can anyone shed some light on the use of Amal carbs on
Guzzi twins??

 A few e-mail threads ago I think Mark was saying something about "SS
Carbs" that the square slide carbs are better, that SS Carbs are
responsible for a lot of loop fires (if I am misquoting you Mark then I
owe you a beer). Sorry for the ignorance but are SS Carbs the same as
the original round-slide carbs that came on the Ambos from the factory??
