First thing make sure the battery is up to snuff, if battery is good, pull the plug and try it,.. then post back.

thanks, but it seems to turn over fine without plug in it and battery is charged up,im wondering if its something to do with timing u think

Well I wanted you to pull the plug in case there was fluid on top of the piston.

Did this just happen, or has been an ongoing battle since the rebuild.

Could be a number of things, timing, valve set, if its higher compression, could even be a weak starter. When was the last time you load tested the battery,.. does it do it when you put a booster on the battery? How are the battery connections.

Easy to turn over when plug is pulled leads me to believe weak battery, starter and/or connections, but I have been wrong before.
