CA not running right

For some reason cylinder # 3 is fouling the plug. If you pull the plug wire off and hold it about 1/2 to 1 inch from plug the miss goes away ? For some reason it is loading up with gas on number 3 but I dont understand why holding plug wire back to where you can see spark jump to plug causes it to run smooth ? Any idea's would be appreciated.

thanks,
PS.
I believe it to be a 1952.

Dennis, Always do the easy stuff first. As Bryan said, try a spark plug. Also, could be #3 wire failing causing the misfire. Switch the plug to another cylinder or the wire to another cylinder and see if it starts to miss on that cylinder. If it does, you've found yer' problem. If #3 still misfires, inspect the inside of the cap for carbon tracking or a crack. Also, inspect the rub block on the contact set. It might be worn out. Just a few easy things to check on the ignition system before reaching in yer' pocket....

Dennis,

That's an old trick. When you hold the spark plug wire a little away from the plug you are in effect increasing the spark plug gap, which increases the voltage necessary for the spark to jump the gap. Higher voltage means - you guessed it - more intense spark and therefore your plug fires. I had something similar happen with an air-cooled engine - in that case it turned out to be bad points.

I'd first change the plug out - I've had bad ones right out of the box before. Autolite 303's work great for distributor systems, Autolite 295's for magneto systems in AC tractors. Next I would change the spark plug wire. Then I would replace the distributor cap and rotor.

Your #3 cylinder could have enough oil fouling that nothing fixes this, but if it's a simple miss and all other things are ok one of the above fixes should help. You don't want to increase the plug gap much - a higher spark voltage means higher voltage across the points - and can eat them up in a short time.

Hope that helps.

Barry,
Champion plugs don't work very well in the Allis ignition system. ACs are my choice after throwing away many "new" champions that misfired. Duey

Dennis, on my C ,with mag. it ended up bein the coil. You probaly should check points, condencer, and valve lash too. one cylinder usally isnt carb problem. first I would swap plug, and wire on # 3, you never know. good luck. Barry

Sorry guys I should have told you I rolled the plug, then the wire. Point and rotor and cap look good (although I know this can be deceivin)and also checked valve clearance 3 times. I just thought it was something so easy I was over lookin it ? Sounds like from all the input I should just give her a good tune-up anyway. I will check for Champ plugs tomorrow. Thanks for all the input and I'll let y'all know ?

Dennis, if its an oil problem try autolite # 75 plugs. Thay are workin real good in my C. oil used to coat plugs after a bit of use, with 75's no problem. Was told by old timer at auto parts store, thay were THE plug for well used,gas powered, construction equipment.
