Quoting Removed, click Modern View to seeCompression test can be informative. Wire to feel piston for TDC is "iffy" & you will most likely feel that you can't be sure trying that method. Wire has to be snaked thru hole around edge of cylinder & is subject to movement by valves. Pee poor method. Generally if there is a cam/crank timing problem , it is gross, not just a few degrees one way or another, so simply 'carefully' & as 'slowly' as possible, feel for beginning of compression & then for end of compression. Then look to see if rotor is pointing at least generally toward #1 at distributor. I can give you a full 6 or 7 methods of finding TDC-compression with varying degrees of precision, but most all are too much trouble, take too long, etc. Point is that close is generally good enough, since one cam/crank gear tooth will change ign timing by 16.36 degrees. If gear problems result in such misalignment so as to make it not run, it will likely be large enough that you will eyeball that by observing rotor position. You can try multiple observations until you feel confident that you have a good average that either looks OK or not.
