I am just breaking in my second build. It seams to rev a little high before the clutch engages. I dont have a tach and this is my first HS engine so I am just goin by feel. Can I just streach the springs to make it engage at lower rpm's or do I need to get a different set? Is this something that will self adjust as it breaks in? I want to break it in slowly to get the most out it. Am I just worried about nothing (as I said I'm a rookie). Any advice would sure help.
