SL/R107: 560sl idle adjustment removing factory seal.
I recently purchased a 560sl with 32k miles. Changed all the spark plugs, wires, fuel pumps and fuel filter. The car runs great on the highway and great once running but has a slightly rough idle and it’s hard to start sometimes. I’m assuming I can fix this by slightly adjusting the fuel distributor adjustment screw but it has the factory seal on it and I wanted to know what methods others have used to remove the factory seal so the idle can be adjusted.
Thanks
