Re: What next? Starter?

Let's go back to first principles and break the problem down to its simplest form.

For an engine to run it needs 3 things

1)Compression

2)Spark

3)Fuel

If it has those three things it has to run, it has no choice.

You say the engine turns slowly. Any six volt starter will turn slowly compared to a modern 12v car. But if it turns too slowly it will not start especially if compression, spark and gas are not exactly right. But if it turns over briskly it will start easier. Could you take a video of the engine turning over?

It is also possible to start and run a 6V car on a 12V battery for short periods (up to 15 minutes or half an hour). Do not grind and grind the starter too long or it can overheat.

If an engine has not run for a long time and the rings are dry a shot of oil in each cylinder will make them seal.

As you had the head off would you say the valves and pistons are all good and sealing correctly? Could you do a compression test?

2) Spark. You have gone over this, have you checked each spark plug individually and are they all giving a good spark? Are you sure the timing is right, the rotor is timed to the #1 plug and all wires are in the right ordoer?

3) Gas. Let's not get into the carburetor at this time.

First address the compression and spark. If they are right, or nearly right, it is possible to start an engine by pouring a little gas down the carburetor.

The first thing is to get it turning over.At this point we only know it is 'slow'. How slow? They always turned slow compared to a new car.

Check out this video of starting a 54 Packard for the first time in 15 years. This is how it goes if you are lucky lol.https://www.youtube.com/watch?v=42yaF9IKTLc
