I've just built a Fuel injected 660R with CP686 12.5comp/ratio, Skimmed head, Over size valves, CromeMolly Rod and lost more.
Without the sparkplug the motor turns stiff but at a reasonable speed. With the sparkplug in it is not possable to turn past compression stroke. Is this normal? The comp ratio on static is about 1200psi
That means very high and race fuel only.
would you advise to pullstart it?
