just bought a 120y and ive tracked down a weber 32/36 carby. problem is im not entirely sure how to get the thing on...can any one help?

With mine I just bought an adapter plate and bolted it straight on used throttle parts off original carbie easy as that

That's what I did but the cable used to slip out all the time and besides pissing me off it happened at some dangerous times. My solution was to buy a redline throttle cable ( the $50 one) that takes a ball type connection at one end and modified it to suit another rocker cover which I had a bracket welded on to. I don't have any pics of it on this other pc of mine so I'll get some later

all i do to stop it slipping its use the original carbys bracket to hold the outer cable inplace. Everything from the A series carb is interchangeable except for the internal workings etc pretty much!

thats right chris I had no problems useing the old carbie's cable and throttle parts cable has never sliped out

The only problem with my weber was where to hook the accelereator return spring to.

what about re-building these carbs? anyone got any tips? I have 3 of them but they've all been sitting in the shed for years!
And how do they rate performance wise compared to su's?

Yeh i had that problem too nismo. I just got a 10c spring from a auto shop and hooked it onto the air cleaner(ramflo). You could muck around and make a fancy mount but meh.

Compared to SU... I would say SUs would flow better. Depends on your setup really, headwork etc. I run a 32/36 because i was given one.

Yeah some people hate webers but I like them, they're simple as piss and it's only when you've broken it that you should start to worry or get annoyed
