Rochester Carby problem

Posted on February 22, 2014 at 6:48am 12 Comments

OK so my Rochester is on the 57 Fleetwood not the 64 but I know I can get some feedback here on the problem... Carby went off the car and went for a refurb. Engine would not idle and the idle screw would do nothing. There was no bakelite spacer which I believe feeds the air to the mixture screw but now have installed that.  Carby back from refurb on it goes and same deal.. The idle screw does nothing and the engine blows lots of black smoke at idle (too rich I assume).. Any ideas what is…


Rocker Cover Restraightening

Posted on August 18, 2013 at 6:12pm 3 Comments

I saw a post here recently on how to restraighten the rocker covers which can flex under the rocker cover bolts.  I have an oil leak at the back of the passenger rocker cover so assume I need to investigate with rocker covers off.  Jason you mentioned how to straighten out the rocker covers. Can you revise that please?

Ballast resistor and petronic ignitor 3

Posted on August 3, 2013 at 8:21pm 7 Comments

hi all -- ignitor 3 is in and r unning OK. but theres a glitch.

ballast voltage to relay - switches 14 volts back to coil (flamethrower 2) then to ignitor 3 - all OK and running. switch off ignition switch and engine keeps running!  there is 4 volts of residual voltage in the circuit. what I would like to do is bypass the ballast resistor and see  if that fixes as I currently run the coil off the ballasted voltage (12.8volts) but would prefer to feed the flamethrower coil the full 14…

63 guidematic issues

Posted by maurice lapoiinte on November 24, 2019 at 3:10pm 0 Comments

 So my 63 guide matic headlamps stay on low beam all the time. I have so far bypassed the system and everything works normal. I have been thru the trouble shooting in the manual but this is where the confusion begins.on my car when the power relay is powered I have low beam and when its not powered I have highbeam, this appears to be opposite what the diagnosis says should be correct.The wiring is all original and no wires have been mixed up.has anyone ever unplugged the 2 wire connector…


Another advantage of the Pertronix III

   Having tried both the II and III I can say the multispark feature of the III offers a smoother idle . It is also easier to install .Does not require removal of the distributor

Stuck at two red (dash) lights!

Posted by Jeff Kinzler on November 3, 2019 at 10:00pm 9 Comments

I hope someone can help solve these two electrical problems that appeared one after the other.

By way of background: The car, a '64 Eldorado has very limited use. It was at a restoration shop for 15 months until last January-  that supposedly did a bunch of wiring repairs including rebuilding the gas gauge that still hasn't worked properly, and the clock that hasn't worked, and re-soldering the broken wires in the drive door. All window and seat controls appear to be…
