My Clark lift dies when under load at idle. I need to drive it with two feet to keep the RPMs up when turning the wheel or lifting the forks or it dies. I thought it might just be a governor issue, but reviewing the F series overhaul manual it appears to have a gear driven governor that only limits max RPM. I haven't found any other references to indicate how the system works or how it maintains idle RPM under a load. Does anyone have any experience with the lift or engine that might provide some tips or references? Thanks.
