Ok if you have weak valvespring will it flatline on a dyno? Also if the spark is blowing out will it flatline on a dyno? Im really thinking its valvespring but just making sure cause racing season is right around the corner <img border="0" title="" alt="[Razz]" src="gr_images/icons/tongue.gif" />

You may be able to determine some degree of valve float on a dyno but without seeing the graph, it'll be hard to tell exactly.

Well had my graph online but its not there anymore. It goes fine till 5200rpms then just a pretty much flatline till 6000 where he shut off. I mean its flat barly any wave to it. Unless my timings doing it. A/F was at 12.5 where it flatline and slowly went to 12.0 at 6000rpms
