TR2/3/3A tr3 timing chain question [master link]

Some time ago I got this timing chain off ebay and it has a master link in it. I see others that have no master link. Is the master link a problem? Does it idicate an inferior chain?

I don't remember whether or not replacement chains had M/L's. It may be there so that the chain can be replaced with out removing the cam pulley and having to slide the crank pulley forward to get the cam pulley off and back on.
M/L should be as strong as the other links.

Nothing wrong with a master link per se, but original timing chains did not have them, nor do most replacements. Given the many problems with inferior replacement parts these days, it makes me really nervous buying internal engine parts from Joe's Screen Door and Triumph Parts Emporium.

If you use the chain with the ML, be sure to fit the open side of the clip away from the direction of travel.

Here's a shot from another Stag owner, who got burned by bad timing components. Unfortunately for him, the Stag is an interference engine, so the pistons met the valves with unpleasant results. A TR3 motor will just stop running.
