Robin,
About the pressurized fuel in the clear tubing to test the CSV for seepage.......
There may be a quicker method than rigging that all up. I looked at a spare engine I have and it looks like you could remove the intake bellow, open the throttle plate wide open, and peer down the intake to see if the CSV is dripping into the intake when pressurized at 28psi. It may require a mirror or a borescope if you’re lucky enough to have one.
So is it a case where the phillips head slots in the CSV screws are all routered out that hinders it’s removal? Is there enough “nub” to grab onto with some Pliars or vice grip?
