After a hone and re-ring, carb rebuild, pods, and jemco street chambers I restarted the bike on second kick

Is there a solution to this? Is there a really exact o-ring to go back in there as the replacement did not seat around the orifice under the plunger like the ol chewed up oems. Also the plunger base is very hard rubber where as the stock units were softer it seemed and had a small impression in them where the sat on the orifice and perhaps seated better.
Any thoughts? I still have the old ones.
Also here is the jetting I chose. Along with Pods, Chambers, Rings, I did polish the exhaust, polish and gasket match the intake ports and removed the cyl bore steel sleeve lips on both of the ports to make them uniform to the post casting.
Initial Settings - Pilot 35, Main 160, Stock Jet Needle and Needle Jet, with the needle moved up a slot, floats to 24mm.
Thanks, In Advance,
Marion
