Well, at the risk of being asked "is it flight tested?", I'll go ahead and volunteer the information that I cc'd the combustion chambers of my heads using disposable clear plastic hypodermic syringes of the type used for giving allergy shots. They are definitely not flight tested, TSO'd, or approved for aircraft use..
Same thing could be done with insulin syringes, veterinary-use syringes, or similar... as long as the graduations are fine enough. The one I used was graduated in really fine increments so I could get down to really fine 'drips' and could also "inject" liquid back into the area where an air bubble normally forms as you near the end of the cc'ing procedure. Of course, you have to keep track of how many syringes-full you use, because the syringe holds only a fraction of the total needed for a typical chamber. But you can shoot in the first half-dozen syringes full before you have to start getting careful for accuracy. I think it took me about an hour to do all six chambers, one by one, including learning the technique on the first one. At least I think it was about an hour because I had to get up and change the CD before I got done. Let's see: was I playing "Round Sounds, Vol. I" or was it a Celine Dion CD? Can't remember...
