Well I was only letting them run for a brief instant, less that one second for each "burst" and I'd wait a few seconds between each shot so it's running at what I would think would be a slower rate than if it was in a running engine. The web site that got me thinking about doing this was using a 12v source so I assumed a 9v source would be less stressful but maybe I'm missing something about electronics.
My main goal was to just get some carb cleaner though the injectors to make sure they were cleaned out before I reinstalled them.
