Jim, I'm sorry if my previous reply seemed a little on the terse side. I am the proud owner of a set of ancient Dunlop optical tracking gauges and checking the track from time to time is not a problem. The last time I checked it was 300 miles ago on service and it was just a shade less than 1/8" toe in (hence my diagnosis). As you will be aware, the track adjustment on a Seven is somewhat coarse which, coupled with the fact that there is inevitable 'runout' on the wheels makes getting it exactly right a bit of a work of art. I work on the basis that anywhere between parallel and 1/8 in will do. And, yes, I do check with wheels for runout. However, I shall check the toe-in again, quite possibly this weekend.
