  1. That's interesting what you said at the end. Because even though I have rebuilt my carb, it still is rich on start up. (Big soot stain on the ground) So what you say could mean I have the wrong pump on and I might be better off with a pump similar to the '47 in the picture above.
  2. I'm no expert with the inner working of the valves in a fuel pump but what you say makes sense.
  3. I've been curious about that as well. I think my service manual says what the flow should be, but I can't remember what it is right now. If the pump that was on the car did have more volume than what it is supposed to be, what effect would that have on the running of the car?
  4. Yes, I believe the ethanol was probably the reason the diaphragm deteriorated originally. I've replaced the rubber fuel line section just before the fuel pump as well. Although I haven't had the car up in the air to have a close look, I think the rest of the fuel line is all metal. Since I've had the car I've only used 94 octane gas.
  5. Here in Canada genuine parts are more scarce. Not only that, but I've found that on several occasions local parts stores show a listing for exactly what I want, but when it arrives it's not correct. I think it's probably that the people classifying the parts don't really know what that particular part is. Perhaps they have a "close enough " attitude. Perhaps there is a "search engine" influence as well. I'm sure we've all searched for a car part and by the time we get to the second page of google we're looking at clothing stores selling socks or whatever. When you tell the parts counter g
  6. I don't have my fuel pump anymore at the moment.
  7. My engine on my 48 Chrysler is a 251 and I want to try and see if I can use a fuel pump off a '47 with the same engine. However as the pictures show the contact arm that rides on the camshaft is different. Firstly the arm on my '48 fuel pump has a bend in it. The '47 is straight. But I've studied the two and taken lots of measurements and I'm pretty sure the only difference is the angle of the wear area, as it touches the cam. However the '47 is slightly shorter, about a 1/16". The picture of the wear mark is from my '48 fuel pump. So since they ride on the cam about the same place onc
  8. Thanks, I was just reading up on that. I'm assuming you're saying the #42 will work instead of the C-723 special tool they mention.
  9. Thanks, I'll read up on it in the manual
  10. Oh btw. Like I said I'm going to try rebuilding the spare carb I hope, if it's available. When I rebuilt the carb we're talking about I soaked all the parts in pine-sol over night. It did a pretty nice job, but perhaps there is something even better?
  11. I'm going to be looking into the electric choke situation soon. The carb is on a 48 Windsor 251c.i. It's a EV1 manufactured Nov. 1947 so I'm assuming it's probably the OEM carb. I'm not sure what the jets are. Thanks for everybody's input
  12. I'm not disputing what you're telling me but I'm not getting a clear picture from your first sentence. I'm going to take apart that spare carb and have a closer look. But I do have another why question. With all of what you've all just told me, why is my carb working almost flawlessly? It has been running without that ball for about 4 months since I rebuilt the carb. I've only owned the car since June and the previous owner said he didn't have any issues with how the car ran. It does spit out a lot of black soot when it's cold on start up but I'm told that might be my automatic cho
  13. Yes I know but the who essence of this discussion to me at least is why????? Yes I know, but the whole essence of this discussion from my point of view is,,,,,, why? Even though hchris explained it. It still doesn't make sense why it's there in the first place. If I'm "Mr Carter" I'm calling the design engineer into my office and asking why are we casting the base with this extension coming off the passageway for the jet, and then creating a pocket for a ball to sit in and then creating a tool to seal that ball in place, when it makes no difference in the operation of the carb in
  14. Thanks hchris. Noooow it's pretty clear.
  15. I read it again and I still have the same question???? I understand that the ball needs to be in place, but since it's not a check valve it doesn't move. It's fixed in place and sealed. So again I ask, what's the point???
  16. oh ok, thanks c49er. So it sounds like if I was to look into that hole it would be a cup shape with a small hole on the bottom I suspect. Similar to the recess that holds the smallest of the 3 balls in the rebuilt kit that is sort of on the opposite side of the lower body covering the "idle restriction tube" . By "staking" I'm guessing you mean like peaning the aluminium around the edge to keep the ball in place? Or could I use some JB weld to hold it in place? Sorry for my over curiosity but why would Carter bother to have that ball there if it doesn't serve any purpose
  17. Unfortunately I didn't take a picture of the inside of the top body. But for those not familiar with the EV1 model you can see the internal tube on the angle just above that aluminium plug. The casting opens up as the upper and bottom bodies meet so the entire cavity surrounding that ball including around the jet is open to that tube that goes to the top of the venturi. I can only assume that air is being drawn down that tube and through the centre of that jet. Right? Wrong?
  18. What is it's function? Like I mentioned it looks like it just leads to the space between the end of the jet and the end of the aluminium plug. As I mentioned my carb is on the car so I don't really have a clear image of what is in that hole but from the picture, it looks like a ball would just slip right through. As in the picture of the carb that has the ball, it looks like it's seated from the inside. If it has no purpose why couldn't I just fill the hole with JB weld? Or just leave it open as it is now? If it's plugged will I notice anything different in how the carb performs?
  19. I've discovered something abnormal about my Carter B&B EV1 carb. I'm missing what looks like a SS ball that is in the same tube that holds the accelerator pump jet. I should point out that I'm not a carb guy so I don't really understand all the circuits and how they function exactly. I rebuilt the carb a couple months ago and it works ok except very rich on start up. I was careful to take many pictures as I disassembled it and made sure I followed specs when reassembling it. However since I'm not a carb guy I didn't notice that the SS ball or whatever it is, was missing. I only found
  20. oh ok. I remember in drag racing pit crews would make efforts to keep the fuel cool because hot fuel robs the fuel of power so to say in layman terms. So I had the impression that's what the heat shield was doing in this instance as well.
  21. I'm puzzled about the purpose of the heat shield. The fuel lines going into and coming out of the fuel pump are about 7-8 inches away from the exhaust manifold. However as the fuel line goes past the exhaust manifold on route to the carb it is within about an inch to inch and a half away from the exhaust manifold. Why wouldn't there be a heat shield there too?
  22. So I'm curious what might give you the impression that I'm driving the car, when the above photos clearly show the fuel pump off the car and in pieces. ????
  23. Until now I hadn't really considered the probability of buying new junk. But of course it's a sign of the times. My engine has about 65,000 miles on it so it's quite possible that the fuel pump is original. Chances are whatever I buy now won't last that long. Hopefully longer that carhartley's experience. My diaphragm does't even look that bad. Just several crack marks but it was pissing out with a good flow of fuel out those holes on the opposite side of the diaphragm. I didn't notice any difference on how the car was performing. Before I noticed the dripping under the car before I parked
  24. Anyways, back on topic. I'm using Chevron 94 since I've owned the car but is there anything else that should be replaced or attended to as a result of ethanol fuel such as that short flexible fuel line just before the fuel pump that I will be replacing?
  25. oh ok. So it is accessed through the end plate, as opposed to dropping the oil pan?
