Call it mild frustration infused obsession, I pulled the mechanical fuel pump.
When I first tried manipulating it manually it was barely moving, and there was a bunch of crud built up in and around the actuating foot.
I sprayed some carb cleaner in the foot area and some chunks of i dunno what, came out. Then I sprayed some cleaner into the inlet and outlets and tried manipulating it by hand and boom it broke free and shot gas/cleaner a good 3 feet across the yard (uh, whoops). Now it pushes, a lot.
Then I measured the rod, on which the tip has slight mushrooming. It comes in at just 106mm, maybe 106.5mm, which is only 1.5-2mm shorter than it should be...but that is still shorter than I expected.
So I think, maybe, it was thirsty. I'm going to order a new $4 rod and see if that was the issue all along. |
I would not trust the diaphragm in that pump. You don't need it leaking gas into your crankcase if it is crusty and fatigued.

It's a good thing my hair falls out on its own, otherwise I would be pulling it out.
New day, new parts. Installed a new cap, wires, and condenser. Also a new coil.
Same sh!77y routine. Fires right up.. when cold. Moment it's been running for a bit it has no interest in firing.
I'm really scratching my head here. I've replaced all the "sparky stuff". Adjusted the valves, timing is on point. Changed the oil in the bath.

I think this might be where I'm headed next. I don't own a fuel pressure gauge, and have no experience switching from mechanical to electric fuel pump.
Here's why I **think** it may be fuel related. I was taking it for a drive today, me and the dog went up some pretty big hills (for around here). The car was really displeased with going up any thing hill related. I thought "huh, seems weaker than usual". But on the way home, going down some big hills, it was acting like we were running out of fuel. At a stop light I had to continuously feather the throttle to stop it from dying, and then shortly after...it sputtered to a stop on the side of the road.
After much feather, cursing, and turning over, it finally caught, and we were on our way...cautiously. We made it home, but I'm really wondering if we have a fuel issue.
If I go with a fuel pump, I found this, would this be the way to go? How did y'all wire it in?

Thanks in advance! |
You can go with the "click clack" pump (cip#c10-41-2010/) or get a Mr.Gasket low pressure pump (the import pump) from your local NAPA (that's what I run in my own car). I only say that as I tend to drive out of state, and I like the idea of being able to get some parts anywhere I might be traveling to. In the USA, the Mr Gasket pump can be had at Advanced Auto, Autozone, O'Reilly's, and NAPA, and most bigger cities have at least one of those places in them.
Keep in mind that you'll need to mount it up front under the fuel tank, as it's a "pusher" pump. Install a new fuel filter before it too. I normally use zip ties to hold it to the beam, as it has it's own plus and ground wires that need to be connected. Some of us who have gone to electric fuel pumps also wire in an impact switch to turn off the pump in the case of an accident (to stop feeding gas to the engine, or a fire if one breaks out). I hope this helps.

Ok,
The new fuel pump rod arrived on Friday, unfortunately I was away (in West Virginia) for the weekend, so I just got to tinkering again today.
I'm ready to set this thing alight soon.
So, new fuel pump rod, I know it's pumping gas into the carb.
Still very slow to start. So I think to myself "clean up the carb a bit". Unfortunately I can't get the bottom carb mount nut off, so I cleaned what I could on the car.
1. is it normal for gas to be sitting in the rubber elbow that connects the carb to the oil bath?
2. Is is normal for the carb to shoot gas out this area by the butterfly and essentially drown itself.
I am attaching a video. For the record yes I had a fire extinguisher right beside me. And yes I now smell like a gas station.

I'm pulling my hair out. I have 2 weeks to get this running so that I can drive it an hour to my storage location.
It does gas shower this everytime I start it.

Sorry I can't help you on the carb questions as I don't have a single carb on anything but my lawn tractor. You might want to ask the 1500 club guys, as they have more knowledge about those carbs than anyone, as they came stock on the early cars.

| Carb top needs to come off, needle seat stuck open, float stuck, something but the bowl is full and fuel will flow from every possible path available. Check your oil for fuel has no doubt run down the intake and past the rings. |
