Carried out this mod whilst my ’34 LFY motor was in bits a couple of years ago. The cylinder spigot partly blocks the transfer chamber in the crankcase and taking a notch out of the cylinder just matches up this port and improves gasflow. Can’t see why it wasn’t done in production ! Motor breathes better and there is a definite improvement. Much easier to get the right cutout with an empty crankcase on the bench though.
Australian section annual gathering next weekend Fri 29th to Sun 31st at 15 Mile Creek Camp (not quite as flash as Abbotsholme) but still time for International Flight bookings !!!
