After impeller change out I can't get Shift Linkage adjusted to find Neutral. Shame on me for not taking a photo before disassembly. Stays in Forward gear. Is the Lower Shaft supposed to be pulled Up or pushed Down in order to get into Neutral from Forward ? What is best position for Brass Shift Linkage Connector Block to be in (ex: 1.25 inches top of Lower Shift Rod to top of Brass Block, etc)? Also does the motor have to be running (i.e. Drive Shaft spinning) to find Neutral from Forward Gear? Thanks in advance...
