Hi,
In my search to synchronize my extra set webers 40 IDA using a bench setup, I came up with the following idea.
Using a suction adjustable vacuum cleaner and some tubing and rubber tubes I could get my carbs reading on a STE level 4 (4 kg./ hr).
As I understood from Paul abbott’s articles this is ok for a 2.0-2.2 liter engine.
I adjusted all throttle valves such that they are very similar (4 kg/hr) already with a certain vacuum cleaner level.
My current set of carbs (40IDTP) on my car are differeing between 4 and 5 and I cannot adjust them any closer using the auxiliary air screw.
That is why I will try to get the 40IDA done this way to find out if I can get them close already. I know that mixture and float level has to be performaed on running engine.
In my current setup I found the influence of the auxiliary air screw is about 0.75 -1 kg/hr. Does this sound as what can be found on a healthy / good running carburetor in car setup?
If so, I will try to make a setup for the whole carb assembly with crossbar linkage to check the 3000rpm side to side balance.
When I am a bit further, I will post more pics and learnings ;-)
Cheers,
Bart
p.s. it is still an experimental setup and will be tidied up a bit more
