[TR] TR4 engine question

[Alex & Janet Thomson]

Any chance that the coil is receiving a back feed from somewhere, after the
ignition switch is shut off? Maybe not a full 12 v but just enough to create
a weak spark?

Fresh TR4 engine that does that "dieseling" thing after you turn off the
key.  It like it tries to keep running but with a cough and then stops.  The
TR6 has an anti-run on valve to help with that.  What do I treat on a TR4
motor?  P.S.  So proud that after 8 years putting my 4 back together stock,
I won first place in the sports car group at the AACC winter national.
