Well the intitial question explains it all, exactly what would I need to do a compression test on a '67 200D? I am looking at purchasing one and I wanted to know exactly what I would need so I could just do it there. Can I just use a gas compression tester? What size fittings are the GPs? Should I do it warm or cold? Heard both ways. I did a search and saw someone's "poor man's compression test." It involved using no guages on a vintage 190D which is pretty much the same as this. Said that once the engine started to warm up you shut if off then just start cranking for a few minutes until it built up compression and fired.
Is it really good to crank an engine for a couple minutes? And while the engine is cranking, aren't the GP's lit anyways?
Thanks
David
