Guys, again I need your know how. My 68 3000 just quit running in August. I thought it was the carburetor, so I took it apart to clean it, that is when I found that the flout was wired up because one of the ears inside was broken. So I put a new carburetor on, no luck. so I replaced the coil, condenser, points no luck, again no go. I need you help, where do I look next. Fall is here and I need to get it running before my wife kills me for spending so much money. any help would be great.
 
You need to troubleshoot the problem instead of throwing money and parts at it. There's 3 things that a gasoline engine needs to run, a good fuel/air mixture in the cylinders, compression, and a good spark at the right time.

First, pull one of the spark plug wires off of the plug and place the end of the wire near a good ground, like a clean spot on the engine, and crank the starter. Do you get a good bluish white spark that jumps at leas 1/4" gap? If not, then try the same thing with the distributor end of the wire that goes from the coil to the center of the distributor cap. Report back the results.
 
What do you mean by just quit? Did it start running funny and sputtering coughing and eventually stalled? Or did is quit like someone turned off a switch? What they do just before they quit is a hint to what's causing it. Don't just throw parts at it you need to trouble shoot it and find out what's wrong with it.
 
Not that I just added parts, it needed them, they were old and worn. I have replaced only the parts worn and weren't working. It was running rich and loseing power then it quit.
 
that's not what I read.

I read you THOUGHT you had a fuel problem.. eventally put on a new carb.. didn't run, then you whole hog repalced the ignition electrics.

i didn't hear any troubleshooting in there.


so.. now that you've thrown parts all ove rit and it still won't run...

does it have spark?
 
@1 check for a good blue/white spark that will jump a 1/4 inch gap.. Do you have that at the coil wire the center wire on the cap and also at all 3 of the plug wires??? If you do not that is where your problem is. If you do then
#2 pull the carb drain plug and let the gas flow for a few minutes. Catch the gas to look for dirt/rust/water. Then
#3 pull the air tube off the carb and make 1000% sure it is out of gear and spin the engine over while holding you hand on the carb intake. You should both have gas at the carb and on your hand and also have a good suction there.

How could you tell that the condenser was "worn"?

Running rich usually means not enough air. Have you checked the air filter? Maybe there's a bees nest in there clogging things up.
 
Maybe I missed saying I did trouble shoot everything. I checked for good gas and air flow, I have good spark, plugs are fine, the timing is right, the distribuer is clean and no oil in it, but It won't fire up. Is there a timing chain on this engine or am I too close to the forest to see the trees. I replaced the old parts because they have been on the tractor from when it was new. What happen when it quit, I was grading my driveway and it started to miss and spudder then it quit and would only crank.
