Strom 150cd carb balancing with straws

[daverclasper]

Hi. Pete once mentioned this technique as very accurate I seem to remember?.  It involved (I think ?), removing the damping pistons and replacing with a straw in each tube. When the straws are at the same height with engine running, then the height of the jet needle pistons are also equal and therefore the airflow into each carb is accurately synchronised.

Can anyone confirm I have remembered this correctly?, please, as would like to give it a go sometime.

Thanks, Dave

there is also a carb balancer that measures the piston lift is equal 

so yes a straw or any means of visualising/measuring the piston lift will give a good clue that both carbs are the same

give it a try   Dave  nothing to loose

I had a balancer in the 60's that had two needles that you replaced the screw in cap and damper with a push in rod/wire into each carb which looked like a paperclip at the top you then pointed these towards each other and could see the respective rise and balance of the twin carbs. I wonder what happened to them?
