Anybody else have this problem?

[burnoutstang]

I took the mustang out today for its first ever car show. The show was about 30 miles away and I drove the mustang there and back. When we left it was about 85 degrees outside and the trip was all highway. Pulling into the show the car started a little lurching. Once we got the car parked it shut off and wouldn't start again. After it had some time to cool the car fired right back up and we made it home carefree in a little cooler weather. I have the duraspark installed and the car runs and idles beautifully but when it gets really warm it has troubles. I've installed a new thermostat and the radiator works fine. I'm almost certain its a fuel issue but I don't know what to do about it. Thoughts?

mine used to do that
i'd rebuild it and focus on readjusting the float

It just gets hot after you shut it off. The coolant isn't circulating and it actually gets hotter.

 

[burnoutstang]

Anything that can be done in the meantime? And adjusting the float as in...?

 

[burnoutstang]

The car shut itself off.

sorry
rebuilding the carb and adjusting the float inside it

what used to happen to me was that it would sit, the heat would soak into the carb and cause the fuel to spill down the carb, flooding it

do you have a manual choke? if so, what happens when you close it completely after it's been sitting like this for a little while?

 

[burnoutstang]

I rebuilt the carb about a month ago and it seems to work fine. I have an automatic choke, but I am thinking about changing to a manual here soon. I was told that a carb spacer may help :

An insulating spacer, that is. Made of something like phenolic or Corian® that will not transmit heat from the head into the carb. Thicker, the better - see if you can go to 1".

Used to have sort of the same problem. I stacked as many gaskets as I could and still be able to get the nuts to hold (about 1/2 to 3/4 inch). Totally eliminated any running problems.

Some of my cars have that problem if I run blended fuels (which is hard not to get in some areas now days). If you are stuck in traffic and moving slow little things like popping the hood to the safety catch seems to help a bit as well as keeping the idle speed up to keep the fan and water pump moving. Until I went EFI I had an big electric radiator fan on my cadillac that was hooked to a mechanical timer. When I would be stuck in traffic or park I would just turn on the fan. Worked great for 9 years and its still there just in case I need it.

When it happens you can also try holding the gas pedal wide open while cranking.
Don't pump it, obviously!

 

[burnoutstang]

Where would I find an insulating spacer like that? And at one inch does that require modification to the bolts that hold the carb on? And i'll look into an electric fan, what kind is everyone using? Holding the gas pedal wide open actual almost got the car started, but as soon as I let up it died.

 

[Asa]

you might have to make one, as for modifying the bolts, just remove the old ones and go to Lowe's or some other store and wander down their hardware aisle, you'll at least be able to find a bolt that will be the same thread, then you can just cut the head off if you don't want to use a bolt

do a search for electric fan, you'll be able to find a huge amount of posts about them and how to set one up

try holding the pedal wide open till it actually starts, then let it off, it might die again, but it should start pretty quickly from there



and you said you rebuilt the carb, did you just change the gaskets, or did you actually reset everything in it?

Scrap Phenolic stuff can be found on eBay...but since it is heavy the shipping might be a bit steep. Any kind of a plastics business in your area may have phenolic material or even a cabinet/counter top dealer/installer may have a scrap piece of Corian that would work. Just make sure it is a grade that is gas resistant and of a high enough heat range especially if using phenolic.

 

[james singleton]

FordConvert, I thought I would mention that from one of your earlier posts about using a timer (a bathroom timer), I installed the timer on a new/old electric fan I installed, and the timer works great! Glad I read your earlier post! Thanks, Jim

 

[burnoutstang]

I did a little looking into phenolic and it sounds like some hard core stuff. If I have to make one, is it something I can do with just hand tools and a saw? Or do I need something special to cut this stuff. When I redid the carb I redid everything supplied in a rebuild kit. repalced the gaskets and everything else.

 

[burnoutstang]

I've looked for phenolic everywhere and other than ebay I can't find it. Will anything else work?

 

[Henning_1966]

Try looking here lots of options http://www.mcmaster.com/

Phenolic sheet is not that easy to get. A 4×4 inch square of 1" thick, would suffice. It does saw, file and sand readily - albeit with a funny disinfectant smell.

Corian can be found wherever vanity units are actually custom made. Whenever they cut an oval in a benchtop, the middle part is scrap.

 

[burnoutstang]

Here comes the redneck question of the day... Would it be possible to use a cutting board? One of the thick clear kind?
