(quoted from post at 11:30:21 09/16/22) How do I get a quarter inch spark and blue? And what is the easiest way to be sure that it is in time?

I am still not able to get it to start after cleaning the points and checking the rotor cap and rotor and I am getting some spark to each of the plugs


You can take an old spark plug and open the gap to 1/4 inch and use that to check for strong spark. I don't think it has to be blue or white.
You originally said that it still runs rough after replacing ignition and fuel system parts. Now you say it won't start at all. Is your battery fully charged? I don't remember if you said it's 6 or 12 volt.
Did you ever do a compression test?


I did a compression check. 1 is 100. 2 is 85. 3 is 105. 4 is 110
Fully charged the battery. 12 v system. Still no start now.

The compression is good enough to run. One soft cylinder, but it should still start. What have you done between the time you replaced "all electrical and fuel and it still runs rough" and now that it won't start at all?
Have you tried starting fluid sprayed onto the carburetor intake?
At this point I would put the old carburetor back on and see if it will at least start.

When the new carb and electric was put on. The tractor ran well enough to run the bush hog and then it ran out of gas. When we put gas in it we were able to get it started once and it was very rough. No it does not start. I tried started fluid. But no luck

When you run out of gas, there's a good chance that sediment from the bottom of the tank got into the filters and plugged them up or even got into the carburetor. Remove the plug at the bottom of the carburetor and make sure you have a good flow through the carburetor. You should be able to fill a pint jar in a couple of minutes. If not, then start checking the filters. There should be one at the top of the fuel bowl under the tank, and another one in the carburetor inlet.
I would still put the old carburetor back on. The after market ones that you can get probably are made in the land of almost right and can cause trouble.

You don't have the throttle lever too far
down to start I wouldn't imagine.

If it won't even fire on starting fluid, you have spark problems.

What next?
I'm sure you are aware of the rotor turns counter clockwise .

If you have decent compression. Does it mean the valves are working properly?

Working and sealing might be two different things.

Working I would consider opening and closing. Sealing would be working without leaking.

When you sort out other problem check compression on #2 with a few squirts of oil. If it comes up might be rings sealing. If not check valve lash. A too tight valve will cause low compression, as will bad valve/seat.

The valves all look to be opening and closing properly. I have all the plugs out and the starter is having a hard time turning it over.
I will attempt to lash the valves and put it back together. Anything else I should be looking for while in side?
I have been running this tractor for 6 years and never a problem.
Is it possible it got hot and blew the head?
