Keith, I may have the same out of alignment problem on my 71 TR6. If I try
to time it with a timing light, it runs real rough. If I advance the timing
until it smoothes out it's advanced beyond the timing marks, but seems to
run great.
I tried to install an electronic ignition last night, but now I can't get it
to start. If anyone has any advise on the electronic ignition please let me
know, it's a crane ignition. I tried to readjust the optical sensor quite a
few times, but no success.
I think I'll probably go back to the points, for now anyway. The last parts
I need to get it on the road should be in tonight and I'm hoping to go for
my first drive in a TR6 since the mid 70s this weekend.

Subject: TR6 Timing chain sprockets
I have gotten into the chain and sprockets and can't find anything that
remotely looks like an alignment indicator-no dimples, scratches or the
like. Are these marks clearly visible on a factory original engine and
if so, does that mean perhaps the sprockets, and maybe chain, were
replaced by a PO? One hint is that the car ran best when road timed, and
the resultant dynamic timing was around 23 degrees BTDC, which always
made me wonder if someone put it back together slightly out of
alignment..
If I replace the sprockets and chain, I will have to get the pistons and
cam aligned again, because I don't have any alignment marks to follow
and the existing alignment may be wrong anyway.
How would I do this?
Also, should a new tensioner be installed?
