Complete rebuild, ran for 1 hour and quit. Compression is good, leak down is good, timing is good, valve lash is good, de-compression is good, ignition timing is good, spark is good, won't start on starting fluid but will backfire through intake. I'm at my wits end, I have more than triple checked everything, what am I missing. Wrench Rabbit bottom, Cylinder Works Cylinder, Hot Cams Stage 2 Cam, New Stator & pickup, New CDI. Interesting though, OEM specs for Cam Lobe Length is 35MM and hot cam stage 2 is 38MM??
