Well, I reckon if i'm going to try the push-start method, i need to
make the brakes work again first.. LOL

I ordered a new harness already. I decided to stick with 6 volts for
now. That decision was made mainly because i already purchased an 8
volt battery to try it out (the regulator was 'turned up' to 8 volts
years ago). From what i've been reading on the internet, the bigger
wiring of the 6v harness will accomodate 12 volts easily, should i
decide to go that route in the future.

I reckon it could be considered such. My dad said he drove the thing
750 miles right before he put it in storage for those 27 years and it
ran pretty well. Obviously, "ran great when parked" doesn't really
mean anything when the rings are stuck in the pistons..

Wouldn't that be considered a lot of mile between rebuilds for that
vintage (materials and motor oils of the day)?

LOL !
Hey, i just thought of something... this car has the Fluid Drive
tranny, so do you think it will push start at all ?

Lack of compression could be stuck valves, a rudimentry form of leakdown
testing could be performed by positioning each cylinder to TDC on the firing
stroke and injecting compressed air through the spark plug hole to check for
the sourse of the leakage.

Pressurized sump points to stuck rings, air escaping from the intake or
exhaust indicates stuck valves.

I will definitely try that!
Thanks!

Yes, I have done that with my 49 Windsor and 40 Royal. FluidDrive
came in two different varieties, a regular 3 speed transmission with
fluid drive, and the M4/M6 dual range fluid drive.

ok! I'm pretty sure this one just has the 3-speed w/ fluid drive.

Mopar flatheads tend to get very sticky valves when parked for a long
time, and they have pretty light valve springs so the valves may stick
open when you crank the engine after a long period of sitting. You can
drown all the cylinders in marvel mystery oil, rotate the engine by hand
a few times (with the plugs out) and then let it soak on the valve stem
seals for a week or so, then crank it over (still with the plugs out) to
clear the oil and then test compression.

But after 27 years, it could be too much for mystery oil to un-stick,
and it could also be that the rings are completely shot from scraping on
surface-rusted cylinder walls.

yeah, ideally i should have just pulled the motor out and
reconditioned it from the get go. too bad i didn't really realize
what a sweet car it is until a few years ago.

Actually, I was reading about the "tip-toe" transmission and how to
shift it.. I think this car may have that dual range thingee after all
instead of the 3 speed..


Drained the coolant today... i pulled out the thermostat and put it in
a pot of 180 degree water and it opened... did it a few times and it
opened more and more until a certain point.. was wondering though if
the thermostat is supposed to close all the way... i'm assuming it
is. When cooled off, this one is not all the way closed.

The Chrysler, DeSoto and Dodge had the M6, PrestoMatic, TipToe shift,
four speed, dual range Fluid Drive. The "second" gear position is
Low/Low-High and the "third" gear position is High/Low-High/High.
Almost all of the time you will use the High range. Shifting is
accomplished by slightly lifting your foot off the accelerator at
about 15 or so, hearing a clunk, then pressing on the gas again. You
only need to use the clutch for reverse and starting, although you can
start the car in gear. There is a fill port on the passenger side of
the transmission whereby you remove the plug from the torque converter
to check the fluid, which is really 10 weight oil. Draining and
refilling requires turning the converter with the plug downward and
letting the oil drain, then reversing the procedure. All in all, the
transmission is very good. Make sure that the electrical connections
to the carb are good and that the solenoid and governor on the
transmission case are operating.
As to the thermostat, it should be a 160 degree opening with a
non-pressurized system. I have had no problems with my 49 Windsor or
my 40 Royal.
