Need tune-up specs.
 

Hi All,

Great forum. New owner here, my first Benz. My local dealership says that the service manual is no longer available! (?)!
Can someone help me out with tune-up specs for a '73 model 280. It's a 114 chassis with a 110 engine (I think). VIN is 11406012015324.
I need to know the point gap and dwell, the spark plug gap, basic ignition timing and RPM, valve clearance, and the recomended oil type/weight for sunny California.
Plus I'd be happy to learn any useful tidbits of information, such as: you need a 14mm hex wrench to remove the oil drain plug (already figured this out).
Thanks.

p.s. Where can I get a manual?
