OK guys, I pulled the head off of my Webra .50 the other day to make certain it had a dykes ring because some were talking about it in another thread. The ring gap is in the center of the back intake port, should I move it?
Assuming the piston hasn't been removed, leave it alone. I haven't had my 50 apart but the Speed 40 and 61 are pinned so the gap runs on a solid part of the liner. toward the rear IIRC. You can tell if it's a Dykes without taking the head off by looking in the exhaust port. A plain ring will be down a little from the top so you can see a bit of piston above it while a dykes is at the top. If you have had the piston out make sure the gap is at the pin when you replace it. If you compress the ring with your fingers and rotate it you will be able to feel it when the pin falls into the gap. If it ain't broke............
