I've just had the engine rebuilt on my 1970 TR6. I'm using a head which was
rebuilt about 2,000 miles earlier, two Weber Downdrafts, and street/race
cam. I notice that when I have been running the car moderately hard, that
when I turn the engine off, I sometimes have "running on." No major attempt
has been made to increase compression, although, some minor decking of the
head and block may have been done, cylinder bore is .040 over, but standard
height pistons. I found running 92 octane helped some; however, the running
one continues.
I speculate that there are some new "sharp" surfaces; however, am concerned
with potential long term damage to the engine. What does everyone think
might be adjusted? Changed? Replaced?
Leaner mixture,
Retard timing
Pay a witch doctor
Just go racing
Thanks in advance,
John Sullivan
