tryin to break in new engine, ruff idle

Still having problems? I have had many holleys have this problem and most times it turns out to be clogged idle air bleeds. Looking down into the carb., they are the larger bleeds towards the outside of the carb. Take your time and flush these out real good. Make sure you get all the crud out and not just move it around. The larger bleeds actually suck in more dirt than you would think. I've seen this cause all kinds of issues from a rough and rich idle to uncontrollable carb siphoning in a non vented system. I've built many dirt track engines and this was a commom problem that many people in the pits would miss. 1 can of carb cleaner and a air hose and I was a life saver. Just my 2 cents worth!!! Good luck and let us know how you make out.
