car has pertronix, lots of performance upgrades including triple carbs, etc
in the last couple of months I had rough running problems, manually turned the
dizzy to see if that helped (it didn't). may not have put it back exactly
right. some of the plugs were black. replaced them, and on advice from my
mechanic who had just worked on the car for other issues (suspension) pulled
the carbs and replaced the gaskets on the deceleration valves. put them all
back and balanced them.
drove for about 30 minutes yesterday, turned it off, turned it back on and off
a couple times quickly, then off for about 20 minutes, then drove for 2+
hours. had lunch, and drove home about 30 minutes. seemed to run well,
except sometimes the idel would be up about 2k, sometimes down in the low
teens.
waited an hour? and the car was a little hard to start. didn't run that well.
went to the gas station, it wouldn't start. waited a few more minutes and it
started. drove home. car was not running well.
this morning I advanced the timing just a smidge and it started immediately.
drove about 15 minutes, seemed ok except when I was almost home the idle
dropped down to zero, and it restarted. put it back in the garage a few
minutes later and shut it down. waited about 5 minutes and it wouldn't
start.
sound like a coil? its an msd maybe 2 years old.
I thought I'd swap out the coil and see. any other ideas?
