The main reason they use a check ball is to have the right size to open them and when you let off the throttle the check ball lifts and makes the opening larger so they close fast enough. If they just had the hole the size for opening the secondaries without the check ball they would not close fast enough. If you leave the check ball out you will have a larger port which should open them real fast and close like they should. As far as I have heard the check ball is there to lift off the gas and make the port larger so they close fast enough. Its gives the right size to open them and then gives the larger size when closing to bleed off the vacum fast enough. Ron



That is right!

Now the question is: do you think my engine will bog from too fast opening rate???
