i definatley will get the co set up, but it the guide on here as ive said before it reads " if it idles fine when hot or cold the co2 level is okay" and as mine idles perfectly when cold and hot and only has issues when warming up surely this means the co is correct. plus all ive change is the injector o rings so surely this wont alter the co2 drastically as the condtion of the old seals was almost perfect.
