I've been chasing down cold start/white smoke for quite a while, which some of you may be tired of hearing about. I recently had my injection pump rebuilt, but the problem persists. I am in the process of fitting a clear hose on the line right before the injection pump to look for air but I happened to pump up my primer and thought I heard a very high pitched sound coming from the area of the pump. This is of course before I started it up and it pressured up. Is this normal, or is this a possible source of leak?
If one of you fine folks is near your 1hz, would you mind pumping up your primer and seeing if you get the same high-pitched sound from the area of your injection pump? This is obviously not while running, and I'm surprised my ears can still hear such a high-pitched sound, but that's kind of what you're looking for. It only lasts for about 5 seconds or so.
If someone can do this and report back then I owe you a future beer.
EDIT: Title change as this moves forward, and thanks to @Rigster for pumping his primer and reporting back to me that his wasn't hissing...
