Oliver---There are some flaws in what your mechanic, and others you
know, say in regards to distributor timing of the TR6.
Moving the dist. clockwise COULD speed up the engine idle speed
until it reaches the maximum rpm that such an advance can make. This
move rarely will cause the engine to "run rough", nor should it cause it
to run "hot". In fact, just the opposite move (towards retard) can cause
these two side effects. The penalties for too much advance can set up
detonation to take place when a load is placed on the engine. To avoid
this, one should not advance the timing to much beyond 12 deg. BTDC,
unless other safeguards are in place. (High octane, knock sensor,
automatic retard feature, etc....and it's always better to use a timing
light to know where you're at as a starting place!

Re; ignition timing
...my mechanic, and others i know, tell me to move the distributor
clockwise? think that's right . . . until it runs badly. then back it
off a bit. or you can edge it forward a little at a time, see how it is,
edge it some more. remember this is not a fresh from the factory perfect
engine. it has some wear, and some modifications.
....the engine will run hotter with an advance,...
and the idle will be higher as well. since you obviously had some
adjustment issues before, just back off the idle screws a few flats,
being sure to do them both the same. you will also have to run the
engine a bit each time for the changes to take effect. slow, careful,
and document/remember what you do each time so you don't end up back at
your mechanics door begging him to undo your mistakes again . . .
