Need Help in Starting

[Labrauer]

Hey guru guys I need some help or information please. I am working on a 218ci 48 Plymouth motor in which I didn't have any fire to the plugs. Checked the coil for voltage and had 6.2 at it. I checked the points and they looked good but filed them anyhow and still no spark to the plugs but had spark at the points. Looked at the distributor cap and changed it along with the rotor and no spark. Tested the resistance on the coil wire and had 345.25 resistance so I change the coil wire and finally got spark to plugs. By the way I don't have the vacuum advance tube hooked up yet nor do I have it plugged where it connects to the bottom of the carburetor. Now my question is this when I try to start the engine I get a puff of white smoke coming out of the top of the carburetor. Thought maybe the distributor needed to be turned and did that but still puffs of white smoke comes out of the top of the carburetor. Any ideas on what could be going on? When the engine was put together I had the timing mark at TDC and the rotor at the 7 o'clock position and I also checked the wires to make sure I had them in the right order. I think that is right. 

 

Thanks in advance,

Larry

Let me be the first to say 180 degrees out unless that is what you mean by turned the distributor

Pull the plug on #1 and check for compression stroke.  TDC on compression is when the rotor should be pointing  at #1 position on the cap.  TDC will also come up on exhaust stroke but the engine won't start since the crankshaft makes two revolutions for a single  revolution of the distributor shaft. It may pop and bang and issue puffs of white smoke or flames out the carb when firing on the exhaust stroke but check your rotor position when you KNOW you're on the compression stroke. 

 

It could also be valves hanging open and your timing is correct but that's a different issue.  Check the rotor and compression issue first and verify before moving on.

Another common problem is having the spark plug wires one position off .

A back fire usually indicates there is some fuel and spark. The back fire is a result of too much advance. This could also happen as a result of spark  plug wires not in the correct order resulting in a misfire.

Static timing procedure should eliminate the above scenarios.

Thanks guys

Hold number one spark plug wire against your tongue. You will soon know if its getting enough spark.. LOL

I saw my Dad kill a 4 cyl engine one time by grabbing all 4 spark plugs at once.  I've never tried it and don't plan to.  Bob
