I have a question for you all. (Its about my "67 Massey Gas Deluxe w/z-145 engine.)

Last week I posted that I was able to solve the wiring issue for my tractor that has been a hassle since it came home last year. (A short had developed inside the wiring harness). It now turns over without a hassle but it won"t fire.

I replaced the spark plugs all but one of them were fouled up. I checked all the connections and I made sure I was getting power into the positive terminal and through to the negative terminal on the coil.

I pulled out the coil wire that feeds to the middle of the distributer and the copper ends were blackened and they broke so I replaced that wire and copper ends. I was able to get a blue spark from the end of that wire to the block. I tried it again and it wouldn"t spark.

I filed the points and it will turn over but not fire. Its been suggested that its either the coil or the condenser/armature assembly. Because of the fact I"ve been at school and working most of the time the tractor sat outside where it stopped all winter tarped up. I"m assuming this is the main culprit.

How can I tell if the condenser points have gone bad? I was flipping through the parts on here last night and saw an electronic ignition. Is this a good investment or should I keep the points/condenser in place? Or alternatively is it the coil not firing - I picked up a new one from Auto Zone last night and it wasn"t able to fire with that on there either.

Thanks,

Christos

I would expect that since you only got a blue spark from the coil wire to ground that your primary ignition circuit is in trouble. You filled the points but you must regap them when you do that. While you have the distributor open, get the points closed and then push radially on the distributor shaft while watching the points. there should be no motion in the points and the allowable runout on the shaft/bushing is like 0.002". If you see motion at the points your distributor needs a re-bush.
If you have a voltmeter measure the voltage at each node inthe primary circuit from the battery to tthe coil and to the distributor. You should see battery voltage from both side of the key switch(key ON and points closed)to the battery side of the coil, UNLESS you have a resistor in the circuit. You should see a very small, but not zero volts on the distributor side of the coil. Make sure that the sign on the distributor side connection of the coil is the same as the Battery ground. If the battery is positively grounded then the wire to the distributor from the coil should come off the positive terminal. When you find and fix the problem and check the sparkusing the coil wire you should have a FAT, BLUISH WHITE SPARK.

Points must open and close, and maintain the proper gap when open. [I'm guessing you didn't check the point gap after filing the points.]

The condenser is basically an electrical storage device. If the condenser isn't storing electricity ["charging"] or releasing electricity ["discharging"] properly, it must be replaced, as there is no repair procedure.

There is no "armature" in the distributor.

I'd suggest replacing the points and condenser--mainly because they're relatively cheap--and then setting the point gap correctly, making sure you lube the distriburot cam with some silicone dielectric grease [usually comes with the point set, sometimes liiks like a pill or a "bean."]. THEN try it again and see what you do or don't have.

Just by reading your note I'd suggest finding freind who is a fairly good mechanic who can lead you though the test proceeder's to see what is wrong then show you how to repair it. You seem to have little or no knowlegde of what you are doing and that can only get you in trouble. I would suggest getting a good book on how to fix automotive things so as to get some knowledge of what it is you are doing. At least you should know the names of the differant parts so that when you read what we say you understand what we are talking about.

Goto amazon.com and take a look they have a lot of good books for beginners on there.

Just my 2 cents worth,I changed my 1550 Oliver to pointless ingition a few months ago and so far so good. I had a huge problem with it drawing moisture and corroding everything inside.
