Electronics are all good.
Yesterday I took some temp readings. After driving for 30 min, I stopped and read the temps:
intake manifold - 124
carb - 110
engine compartment - 118
thermostate - 180
All seems good to me.
IMHO, it's gotta be the additives in the gas that are boiling off at the low temps. I pulled the fuel line off and started the engine after sitting overnight.
I noticed that there was no fuel at the carb inlet. Most time I will get some fuel to spill out of the carb when I remove the fuel line.
Also noticed that when the engine started it took 1-2 seconds for the fuel to come out of the hose. Once it did it was good volume and pressure.
The fuel pump is new so it should not be running back into the tank.
I think I am going to try to find a gas station that offers gas without additives. I know that we used to be able to get racing fuel at some stations but I havent seen that in a long time.
My other option would be a electric fuel pump. Dont really want to do that because I tried one 20 years ago and they were so noisy and loud I took it off.
As I stated in the first post, 6 yrs ago I did not have this issue, the motor would start as soon as the key was turned. The carb, motor, electronics are all the same when I stored the Jeep.
Still going to try a new spacer between the manifold and the carb. We have the Jefferson auto swap meet coming in 3 weeks. Lots of good stuff there.
