So I have hung onto my grandfathers car for 30 years and not done much with it other than start it and move it once a year or so. Not sure if some guru's of 70's vehicles exist here.
1977 Cutlass with a 260 V8. Perfect car for a 16 year old next summer.
1. Temps go to 230. Then stalls and vapor locks.
I replaced T Stat after testing both. OE opened but not much and it didn't open till 210/212. New Stat opens well. Thought that was going to solve problem, but didn't. I dropped level of coolant so I could see flow. Used camera and no corrosion or blockages on outsides of tubes on cap side. Flows well through tubes once stat open. When temps go past 215 it is a torrent in the rad. Fan was not blowing well once hot hot. Removed and can't get clutch to lock in even with a torch on spring so I have ordered a new clutch. Not here till friday.
2. I can't seem to keep fuel in the carb?
If car sits for a day or two the bowl is empty and will not start unless I pour into the vent. Once started it is perfect. Pump is pumping well when I take fuel line off so I am unsure why it won't fill bowl when cranking. Can it be leaking back through the pump?
3. The diverter valve in snorkel never opens to allow fresh air? I have played around with the vac lines and ended up disconnecting it to keep it open. I am assuming part of the vapor locking was always chewing on hot air?
Any lost wisdom that can be passed forward?
