Carb Fuel Delivery Question

[55 Fargo]

Hi all, since it is till like fall here, will be 55 today, its 52 right now.

I took the 47 for about a 15 mile ride, 1/2 way, at an intersection of 2 highways, as I was coming to a stop, the car suddenly became fuel starved, as I was pumping on the gas there was nothing, the engine finally stopped running.

I had to push the car to the shoulder, some woman driver just about hit me as she was turning behind me onto the same highway, she had no patience for an old car.

Underhood, the coil felt warm, but not hot, but the engine was probably warming it up.

There was a heater hose against thefuel line that supplies the carb, could that heat up the gas possibly.

After a few minutes, the car started, but sounded like it was flooded or something.

I took off, went about 55 to 60 mph down the highway to my road and then home,no troubles after that.

One guy did stop, to see if he could help, so there are good samaritans out there.

Not sure what this problem is, if it is fuel related or ignition related...................Fred

Fred,

Don't think it was the coil. If it was, it would have given you trouble when you got close to home again. Sounds more like a fuel problem, possibly vapor lock or the carb. may be flooding out for some reason.

Hi Norm, I tend to agree, plus an overheating coil, would n't cool in a few minutes either.

I did have one heater hose touching the fuel line to the carb.

Another thing, at times when i go for a drive, and when I come to a stop, the idle is higher than it should be, possibly the accelertor pump is sticking.

Another problem, is the heatriser is in the cold seized position, this means all the exhaust gases get circulated around the carb. maybe evn getting the carb warm enough to vaporize fuel, just a thought.

Other than that, not sure, possibly a sticking carb float, will have to correct this.

Other than these problems, this car is running and driving great, still could use a front-end alignment, the steering is slightly more losse than it should be , but the car travels straight ahead, no wonder, and it corners nicely.

It is noisy inside because of no carpet, door panels and headliner, but it should be nice and quiet after these are installed, the front vent windows are a little noisy as the weather strip is old and worn.

The 3.73 rearend makes a big difference, and no issues off the line either,no extra revving to get going, just release the clutch and go.............Fred

The heat riser could atleast be part of the problem. When mine was stuck I could drive maybe 2 miles or so before it would starve and die. In the Summer it would even happen faster. Thats my story and I am sticking to it. Eric

Fred, don't forget the fuel pump. If you have the type with the glass bowl, check to make sure it has fuel in it, if it happens again. Fuel pump could be headed south on you too.

Fred, this may be stretching it a bit, but it's possible. Maybe nothing is wrong with the fuel system. How much gas did you have in your gas can when you came to that stop. If it was low, maybe the gas moved forward in the can away from the pickup tube so it couldn't pick up any gas. Then when the car stopped and was level again, you were able to pick up gas again. You may have just gotten an air pocket in the gas line when that happened.

Mine went out yesterday on me.

After about 2 hour freeway drive I came to a stop and the idle seemed lower and lower. Next stop the car died. Was a son of a gun to restart. Once it did it acted like it was flooded. Drove it home. Started it again, but still took a while to start. Parked it, next day it would not start at all. Undid a fuel connection, and it was getting plenty of fuel. Went to the coil, bingo. Oil on the outside to the touch. It had sprun a leak at the seal. Could not see it by eye.

Sure enough put in the spare and fired right up.

If your getting fuel then it has to be ignition.

Just because coils fail with over heat does not mean they do not fail other ways..

Good luck.

I thought of that too Norm, just before the engine became whether fuel or ignition starved, a was driving around a sharp bend in the road just before stopping at the next highway I was to go down.

But it also does the hard start after a good run, when it does fire, it's almost like it has gotten too much gas, so I am scratching my head on this one.

Eric, I firmly believ having a heatriser stuck in thecold position, will cause problems with heat and fuel delivery or atomization. Except if it is real cold outsidew, I definately can see this being a problem.

This winter, I plan on removing the manifolds, fixing the heatriser, installing new gaskets on the valve covers and manifolds.

[Plymouthy Adams]

could be a tad high float level and the engine was temporary flooded with spash over....engine dies..is flooded...hard restart..or wait till you evap the fuel in the warm engine and blow it out the back..if this happens again..try holding the petal to the floor..this cuts off all fuel..max air in...keep it there till engine starts...best way to start a flooded engine

[55 Fargo]

The heatriser, shall be fixed, all the fule lines replaced, and positioned correctly, gas tank installed, a complete going over of the carb, and ignition system. I plan to do this by spring driving season. although it feels like spring here today, must be about 60 degrees, but extemely windy............Fred

Fred, I am still having trouble with my car, no power. I think maybe I will try the coil. I checked the oints and they lloked good and changed the condensor to no avail. Coils are relatively cheap and could it hurt? Eric

[55 Fargo]

No it won't hurt to change a coil. How about the vacuum advance, is it operating, do you have good fuel delivery.

Sparkplugs and wires are in good shape, the low tension wires to the coil are in good shape and not shorting are they.

fuel pump, isit putting out enough fuel, are the gaslines clean, is a filter plugged up.

The carb, is the accelarotr pump working, have you tried different carbs if available.

Does the engine rev up sitting in neutral, but has a lack of power under load.

Hopefully, the members of this forum can help you trobleshoot and correct this problem, will do what I can, but I am no expert, or I would not have posted this thread to begin with.

There are a few wise Doctors on this forum, the rest of us are interns or med students trying to learn, myself included.

HI Fred!

I tink you probebly have fund the problem self,During my summer tripp I've the

same problem but whit me there was overhiting as well.

since you wrote this in the question I think this is the problem

(There was a heater hose against the fuel line that supplies the carb)

You can also try to move the coil away from the engie..... Roar.

Ps what date did you send the tierods? they havent come yet.

It's -4,5 c outside here now at 21:20 and there have come some of the wite stuff too :-)

[55 Fargo]

Roar thanx for the reply, the tie-rod ends were shipped at least a month ago, maybe there delayed n Norway's customs Department, sorry they have taken so long.

It is extremely windy here today, almost doing damage type winds, it is about 60 degrees or 15 c outside,now snow, but we may get flurries overnight.

I will call you sometime this week...........Fred
