The pump skipped for sure,because we made the mistake of removing the locking nut on the housing,before installing the new chain, allowing the chain to skip. I actually heard it!,I have lined up the gear on the cam, and lined up tdc on the balancer,then attempted the drip test{actually bought the tool]. Lined everythin up at 24 btdc,still no luck. i cant seem to get the pump right.
