I just got this 63 deville. It runs rough and clearly has
issues that need to be worked out. I have no idea where to start. I came here hoping you guys would be so kind as to walk me through trouble shooting the engine.
it takes a lot to get it started once it’s running it burns oil and if you don’t keep gassing it she stalls. It does drive but second gear is a hard shift so that probably needs work too.
You will cause heat damage to your starter ( burn it up ) and battery if you hang on the key the way you are
Let the starter cool after trying to start 15-20 sec
Do a very complete Tune Up —including the ignition wires if you do not know the engines maintenance history
Fresh points and setting the timing should show a big improvement in starting and running
Is the 63 Cadillac a new car you acquired or do you have a history with the car ?
I know nothing of the true history. Guy I bought it from was unsure himself.
Can you install new points and do the timing for starters ?
Pls get yourself a 63 Service Manual for your year Cadillac as it will be the answer to correctly doing your maintenance on your Cadillac as required by Cadillac
Thank you! Printing one now.
Some basics could be checked first:
- measure compression in each cylinder
- is there spark in each cylinder when it runs
- choke seems to be not working at all
- carb adjustment and ignition timing
It is not 63 engine but older.
Real good observation
The location of the fuel pump on top of the engine is a sign that this is an earlier engine than 1962 from what I think I know
I had a 62 convert so know the 62 63 ( 390’s ) and 64 ( 429 ) engines have the fuel pump on the lower front drivers side of the engine
So this engine is earlier than those
Possibly a 58 to 61 engine ——but just my best guess
