It will not build fast enough.
Usually when things are working right, No vac leaks, the lightest white spring is way way too light causing the secs to open too fast.
Generally a medium silver ( plain), yellow or purple spring is best for performance use.
That's what I thought. I thought the White one was way to light to be functional for most situation and car set up's
I checked cork gasket it's there and intact but I'm not saying it isn't leaking from there. I'll probably will replace it just because if it's not a problem now it soon will be. Thanks
