Hi, I just rebuilt my two Zeniths and have put them back in the car. I can't get the car to idle without really opening the throttles.

I put the UniSyns on them and there seems to be a vast differnce in suction between the two. One is sucking off the scale the other doesn't change much.

I am trying to figure out which one has the problem.

When I put my hand over one it sucks my hand quickly down and then the car idles faster.

The other one when I put my hand over the throat it just seems to be lightly sucking.

Which one has the problem? Before I did the rebuild neither of them seemed to have as much suction as the one that is sucking hard.

Thanks
Eddie
