Cant seem to post pictures here but hopefully my explanation will suffice.

Installing a new timing set, dots are crank gear at 12 and the cam at 6, I notice that these seems to put the engine at TDC every time (on the #1 piston ) and Im assuming its on compression stroke, ( since both valves are closed ) am I correct?

Does this pretty much sum it up for any engine...I mean I know that they are not all at 12 and 6 some are at 12 and 12 but if the dots are lined up correctly is it a guarantee every time that your at compression/firing for the #1 cylinder?

Thanks
