<p>What is the temperature rating on your thermostat? If it’s lower like a 160 degree you’re more likely to se more fluctuation on the gauge. Also I think you’re better off getting an actual reading of the coolant temperature than going by the gauge, if the sending unit was ever replaced it may not provide the correct resistance for the gauge to give you an accurate reading. It’s possible that the steep incline could’ve had something to do with you stalling, did you have a full tank of…</p>

<p>first off the bat,,, temps here have dropped considerabley,, 80s.. and the car temp has held at a much better, lower level,, just barel over the 1/4 mark,, creeping to the 1/3 but hasnt been near the mid line since. it starts just fine,, runs fine,, leads me to believe the heat was the primary contributing factor, but i have picked up some of the parts ot change the fuel filter. i will be done with the 500 mile break in in a afew days, then take it on a litlte hour to two hour excursion to…</p>
<p>first off the bat,,, temps here have dropped considerabley,, 80s.. and the car temp has held at a much better, lower level,, just barel over the 1/4 mark,, creeping to the 1/3 but hasnt been near the mid line since. it starts just fine,, runs fine,, leads me to believe the heat was the primary contributing factor, but i have picked up some of the parts ot change the fuel filter. i will be done with the 500 mile break in in a afew days, then take it on a litlte hour to two hour excursion to bozeman and back,, see how things go,,</p>
<p>my neighbor down street has basically cut out the old wiring, put in new or reattached where needed. cleaned up engine bay, put that aluminum cover on lines to protect as you suggested,,also, put protective sleeves on a couple other places where spark lines were close to gas, like near the accelerator pump,, for the reason you siad,, if a stray spark or lot of heat builds up,, and a little gas has gone astray. he has educated my on other things engine wise,, and on my 73 eldo convert,, he got the ac running,, damnedest thing,, i had about four controllers behind the glvoe box, i had stashed, he did whatever he did, pulled good pieces off each, tested each, replaced on a base unit, tested for what ever ohmage or amps or whatever you test for on those things to be able to push those roads and little motors and gears aroudn, and damn if he didnt get aht thing running,, all teh speeds on the ac unit regulator work, auto, hi low, defrost,, heat cold,, took him three days, but he got it.. never looked at a manual,, he apparently has a unique ability that he has acquired over time and a natural understanding of electrical and mechanical things... most of his career was in the fleet mechanic shop at Yellowstone NP,, fixing diesels, dump trucks, snow machimes, bull dozers,, just about any engine the park service has,,.so his knowlegde and willingness to show me and share has been hands on helpful. he explains what he is doing, why he does it, and while i can only absorb so much at my vintage age,, its a late education i am enjoying,,, i really think he likes these old rides..</p>
<p>i will forward a couple pictures of the engine as he has put on the protections etc,, give you an idea of what it looks like, im sure as it should be,, no loose wires dangling around, all taped up and clean,, actually looks good!! </p> Well, i let it sit overnight,…tag:6364cadillac.ning.com,2021-07-27:6543066:Comment:2751092021-07-27T16:28:10.504ZKim K Kaiserhttps://6364cadillac.ning.com/profile/KimKKaiser
<p>Well, i let it sit overnight, went to start this morning. Still no go. Went tp the mechnic that lives down street who has been giving me theory and engine lessons on mechanics to help me drag it home. He open hood, tinkereid w the carb. I was in truck getting straps out, then i heard the engine turn over. It started! He drove it home.

<p>Well, i let it sit overnight, went to start this morning. Still no go. Went tp the mechnic that lives down street who has been giving me theory and engine lessons on mechanics to help me drag it home. He open hood, tinkereid w the carb. I was in truck getting straps out, then i heard the engine turn over. It started! He drove it home. It was his assertion that the extreme heat of the day, at one time was 100, but 90 or so when i went out, the heat built up during my conversatoin at idle. A vapor lock situation occured. He went on the explain it in some terms i coukd understand. He felt i may need to re calibatre the choke spring as he felt it may be a little slow to react. But we left car idling for 15 minutes, no excessive heat build up, ambient was about 75. Bowl was filling up, running just fine. So, feeling of looming disaster has been temp averted. I also learned about and actually understpod mechanics of vapor lock, at minimum, i got some education and can hopefully kno this if it happens again. Thanks for comments and considerations.</p>

<p>Still working to end breakin period! Probly gonna drive in mornings till the oppressive heat goess away, supposed to be over 100 todsy.</p> Looks like you have a problem…tag:6364cadillac.ning.com,2021-07-27:6543066:Comment:2753132021-07-27T11:29:03.033ZCees de Bunjehttps://6364cadillac.ning.com/profile/CeesdeBunje
<p>Looks like you have a problem with the fuel pump. Check the amount of fuel coming out of the pump by loosenig the tube from pump to fuelfilter.</p>

<p>A quick up date from above. I let it cool, went bk, tried to start it. Like not getting fuel. I know its not out of gass. Noticed fuel bowl at probly a quarter or shade less. So i dropped a liyttle gas in carb. Hoping to get things going so i can get it out pf ladys driveway. Well. It tried to start. Then a litte fire broke out in carb. I got it out very quickly.

So i dropped a liyttle gas in carb. Hoping to get things going so i can get it out pf ladys driveway. Well. It tried to start. Then a litte fire broke out in carb. I got it out very quickly. Still noticed no lift in fuel bowl level. So maybe this isnt all heat but fuel to engine. What would you think if it now wont start. Could there be a vapor lock. I run the high test gas. Could the overheat be related to no fuel?</p>
