Took my 60 to go see the Dr. 70-75 (82 4speed 33s) both ways 30 min run. Made several similar and longer runs over the last 2 weeks, nothing special. Try to stay 5 to 10 mph below, speed limit so I'm at the bottom end of legal. Gauges all looked fine the whole time.
On the way back, put in the clutch exiting the highway to stop at traffic for first stoplight.
Idle slowed down and died while I was coasting to a stop clutch fully down. .
The in traffic she wouldn't start. Pumped the Gass,, Pulled the choke nothing worked, not even a sputter. , Hit the hazards and waited on the light. She usually starts on choke cold in a few seconds, and effortlessly warm.
Put her in gear was going to use the starter to creep her onto the shoulder, but she started after a few seconds of non stop cranking, maybe 5 feet of movement... choke was still out so idle was high, pushed it in and really rough low idle, with decreasing RPM, trying to stumble and die. Start above 1k quickly stumble down below and try to die, used choke and later accelerator to keep idle up and limped her home, maybe 5 min at speed 25-50. All gauges looked fine before, during and after.
Volt meter was barely above 12v on starter battery circuit when running.
By the time I was home, the idle was fine, rock solid, restart was fine, issue was gone.
Been replacing vac lines lately mostly one at a time , so I can't mess it up. only a handful left to do. Found a bunch of lines that were not hooked up. Fixed those as I went.
part way through vac lines, started to have a occasional stutter taking off at stop signs with low rpm, but otherwise runs OK. Maybe she's running worse, maybe im getting lazy with engine RPM. Been running shell premium since this started to get any gunk out and she runs, a hair better .
When I got home Engine compartment was very hot, even the fender uncomfortably hot to the touch. Engine temp gauge never left the middle, (maybe it's not accurate?) .
Noticed I never hear the carb fan when I shut off truck, as I did with my previous 60... So maybe vapor lock when she died in traffic? can that cause rough idle? but I still have no idea why did she die? Shouldn't vaporizing Gas cool it back down in seconds once it's running?
My thoughts are either
Gunk in my carb idle passage that cleared itself, or something heat related, as I'm in Texas, and was in traffic at highway exit. but temps, are below 90. Last summer she, was not reliable enough to drive consistently.
Going to get radiator cap with thermometer and validate temp gauge. Going to see if i can get more accurate readings of engine compartment temps.
Have a 10 micron fuel filter I was going to put as close to carb as rubber goes.. To catch any gunk going to carb. Is it all hardline from just after fuel pump to carb? That's all I see...
Any ideas what else I should check? Or what might be the issue? I'll go over the vac lines to be sure I didn't mess anything obvious up... Anyplace I should check first? Had to glue altitude comp valve, and one of the low temp idle switch's back together with straws in the nipples, but neither seems to apply here.
