Valve Lash


The engine will fire on 40 lbs of compression. If you preloaded much more than .003 it won't start. Also, builders will preload after a break in run on the Dyno when the engine is hot. Even then, sometimes it won't start when cold. Why do you think the electric starter made it's appearance


If you'll crank the engine and run it up too 200 degrees and then adjust the valves too barely have compression-- you'll be very close. Let the engine cool completely--ya shouldn't have any compression. See if it'll start-- if not do again.
