I rebuilt this engine about a year ago. Great compression and running good other than not getting past 5000rpm at WOT or after I throttle down the engine will not idle good, it surges and dies and restarts. Ive set the tdc with a piston stop and marked atdc and btdc and set the midpoint as the true tdc. I performed the throttle snap procedure to set the throttles fully closed, then set the idle timing and the set the WOT advance. IT runs great but not getting past 5000 rpm at wot. Any help would be gratefully appreciated.
