Timing changed after Cap + rotor swap?!

lets not discuss here if you can move the cap with the snaps on or of and stuff like that, lets keep this on topic. i think diymirage has a point here

by taking the snaps off and moving the cap is a very quick way of telling the timing, instead of fumbling a wrench all the way to the hold down bolt.. it sounds like a good idea to try.. worst thing that can happen is a backfire or an engine that stops running, i was thinking about the cap maybe having the points on a diffrent position too.. i will try the snaps-turn-cap-strategy
