Hello all, I was advised to use a 32 DMTR carburator for my fiat 128, but there are a whole bunch of different 32DMTR's .. Currently I am looking at an 32DMTR200 ....what does 200 stand for? Is it suitable for my 1116cc
Suffixes after the model name usual give some indication of what vehicle the carb was fitted to standard, and the jetting it was installed with, as well as any variations from the original design.
Are you sure that it just says 200?
Not something like 32dmtr24/200 or 31/200, or maybe 33/200??
31/200 is a Beta 1.3
24/200 is a Beta 1.4
33/200 is Autobianchi a112
all variations on a theme...differing venturi sizes and standard jetting
It looks like a regular dmtr, but it has a fuel bowl vent and an additional linkage arm on the choke lever...most probably a US variant for a 1300 128.
to fit up nicely to a 128 you would also want the rubber gasket and the four steel sleeves that seal the underside of the air cleaner and the steel plate that mounts on top inside the air cleaner... and the air cleaner assembly itself... the noise from a small rectangular sports air filter gets tiresome after a while, and they draw in lots of hot air too.
The stock air filter assembly does a good job of filtering and reducing engine noise.
Thank you all for this useful information!! So hence the "A"+200, the carb is coming from an american market, thereby being a "detuned" version, and not a good fit for my 1116 then?
no emissions ports,and it has the original setup of having an idle air correction screw that is used to set the idle mixture most accurately.
the idle mixture (fuel) screw is number 23 in this diagram,and the idle air screw is number 16 above it.
An A suffix doesn't mean 'american' usually it stands for 'avviamento' which is idle speed correction either for emissions or ancillaries (like air conditioning) ... usually, but weber nomenclature isn't an exact science.
best guess is that carb is actually a 32DMTRA 1/200... which is a US market carb.
And the throttle linkage being on the wrong side...and the primary and secondary throats being interchanged... won't do much for the low throttle mixture distribution...
Just because a retailer has knocked together a kit doesn't mean it will work flawlessly...on a twin cam they fit OK, on a sohc it's just positioned all wrong.
That particular reseller has a 32/36dgav on everything,from a single barrel 850 to a 2litre 131... http://www.weberperformance.com.au/index.php?cPath=2_88
and "Minor installation modifications may be required to attach to existing throttle linkage"
