I just went through something similar with my TR6. At first it was a slight
miss. Then the miss got more frequent and worse. Finally, the more/hotter it
ran, the more it misfired, backfired etc. This all happened over about a 3
week period. I replaced the coil today and all is well based on driving it
for about an hour tonight. ISTR from an old list posting that a bad coil
gets worse as it gets hotter. Anyhow...so far everything seems to be working
great. Fingers crossed :-)

Subject: TR3a misfiring when hot
I have a 1961 TR3a which has just had a complete engine rebuild. It runs
fine while cool, and sometime fine when hot (operating temperature). But
every so oten after being driven a while, it starts missing and sputtering,
feeling and sounding just like 1 or more cylinders were not firing. The
mechanic at first thought that the plugs were loading up due to incorrect
choke usage, but we replaced them and no difference. The problem here is
that the mechanic passed away over the winter and I've not gotten to see his
assistant, who is now in business for himself (but on vacation now). Any
ideas? Thanks, Allen Cohen
