Front Drums, slow starts...

Hi All, I've been searching for a set of aluminum drums for my'65 Riv and Kanter has come up dry, any suggestions? Also the car takes along time to start. I'm thinking the fuelpump is worn or leaking back. I think replacing it with an electric may be an idea, but am leary about line lock, anyone?
Thanks Ian

 

Don't just go replacing things

An electric fuel pump is not needed. They can be a perfectly good thing, but why do you feel you need one? You'll also have to put in a switch to shut it off if you stall, if you go that route, and probably a regulator as well.

maybe if you describe your starting problems in more detail, we can help

To me it sounds electrical in nature. I just had a battery go bad on me that showed 12.3 volts at rest, and would not benefit from a boost from a battery charger.

Hard or slow starting can be many things. If the fuel pump was bad, why would it 'build up' pressure?

I'd start by checking the timing and replacing the fuel filter, personally.

 

Maybe here on ebay o No:

 

Sigh

I've replaced plugs and adjusted timing, the points, cap and rotor are O.K. The car starts right up after it is run, if it sits over night it takes five minutes of cranking to get it to fire. When I replaced the fuel filter it was dry indicating leak back. At $80. the mechanical and electric fuel pumps are equal in cost, I think the advantage is with the electric but wonder if it should be mounted close to the tank or if guys have just mounted them at the front, as far as I know these pumps are set up to pump the 7-10 required by the carb. If you know of another possible cause of delayed starting let me know.

 

I think my point is that while an electrical fuel pump isn't a bad thing, it's treating a symptom and not the disease in this case. I'm only trying to help.

When I was setting up my old electrical pump, they ran higher pressures, needed regulators, and shut-off circuits. Maybe that has changed

 

What carburetor do you have? Perhaps it's leaking underneath and draining overnight. It's normal for some of the fuel to evaporate out of the carb after a few days, but not overnight. Sometimes you need to pump the pedal a few times before turning the key.......I always forget to do that out of habit from being used to my other cars. :bglasses:

 

Thanks, I think its a carter carb, once the car is up and running she will run fine until full throttle then bog. This symptom decreased when I replaced the fuel filter. I came up with a replacement mechanical pump for $40. and am planning to go with that. I know new cars have a sensor to cut an electric fuel pump on impact but I don't think they are mandatory on retros.
I agree that sometimes moving from factory design creates problems, if it is the carb leaking an electric would just agravate it.
I don't normally like replacing parts that I don't have to however fuel pumps will often give warnings by way of reduced performance and I would rather spend the $40 and know I've got a good diaphram,(oops).
I haven't heard from anyone with dual quads and it would be interesting to see how thirsty they really are. Thanks Ian

 

Here's your problem.......mine did the same thing........Carter's don't leak out the bottom like q-jets can do. The trouble is with your accelerator pump plunger (that's an internal part in the carb). Those carbs use a leather plunger, and sometimes even the replacement ones will cause trouble if the skirt is too short. That's also what's causing your full throttle stumble.

When you look into the carb with the motor not running, pull back the throttle.........it should shoot a steady stream of gas into the carb. Drips and broken stream don't count.

If you are ambitious, and confident in your ability to repair your carb get a good quality rebuild kit and be sure to soak the new plunger in gas and spread it real well before installing it or it will also not work properly. Hope I have helped.......you don't need a fuel pump.

Yes, dual carbs are more thirsty, but not much more than a quadrajet. :bglasses:

 

Right on

Thanks, any idea on where to get a kit?

 

Try NAPA.....they seem to stock a lot of that stuff and it's professional quality. :bglasses:

 

Carmen

I searched your earlier post on accelerator pumps and found that you preferred one from a guy called carmen. Any advise? Thanks Joe.

 

Carmen could sell you a kit........he could also rebuild your carb. He does a superb job. If you can wait call him 716-693-4090.......tell him I sent you and mention to him the problem you are having. Good luck :bglasses:
