Engine potential
After rebuilding my engine I cannot get over 5k RPM, it starts missing badly. Before the overhaul I could get over 7k with no cutting out. I'm running 12 degrees advance. I've replaced my stock fual pump with a Holley blue electric pump. Any one got any Ideas on why I can't get any higher on my RPM.
Also this is only under a load, because I can sit in the driveway and rev it over 7 k and it doesn't cut out at all,,,just when I try to run it hard down the road.
