International A Not Running

A 2nd question, is a special spark plug wrench needed to remove the spark plugs? My sockets seem to think to get into the recess to get on the spark plugs.

It stings when you assume one thing and then find it's another, especially if you have the dealer get involved. I'd bet if you asked the dealer in the first place, he would have checked the fuel supply, ruled that out in 1 minute (unhook the line and let it run into a coffee can) and then moved on to the electrical system. One thing years of working on internal combustion engines has taught me: 90% of carb problems are solved in the distributor or magneto. Good Luck!

Good Luck,

I stopped by the local electrical place, whom I have gotten to know fairly well over the years with several old tractors. Basically they said no way to test coil. Fellow said could replace the coil for $15. Stopped by NAPA and they are sold out of $15 coils, but have a $40 one, but could not explain the difference (other than $25 more). So they are getting one in for me tomorrow. While I am doing it I will replace the points and condenser. Thanks for the information and help. Larry

I think some of the offending material was bark from where people have used a stick to measure remaining fuel. It adds up after 50+ years.

The standard way to test a coil is to replace it with a known good one.

Good luck with yours,

On that same tractor I did replace the coil, only to discover the coil was not the problem...do trying to avoid that but I guess for $15, I can spring for a new coil.

Thanks again for the words of wisdom. It may be a piece of junk in the line yet.

Does your tractor have regular spark when it quits running ? You can use and inductive timing light or an other spark plug.

If you have got sparks, take the drain plug out of your float bowl (I'm assuming it has one) does the fuel run out in a steady stream ?

If you do decide to junk it, you can part it inmy fence row.

Do you have another condensor laying around that you could try ? Usually it is the electrical stuff that is affected by heat. And it is usually the coil that craps out.

You can check the coil with an ohm meter. Try measuring the resistance between the two small terminals, between each terminal and the HT output, and all three and the case when the coil is cold. There should be a couple of ohms, not zero and not infinite. If it is hard to get a steady reading, try disconnecting it or an analog meter. Check it again when it stops running. See if the readings are the same. Be sure that the ignition is off, if there is any voltage involved, you could burn up your meter.

Same with the condensor, but they are made to store voltage, so be sure to short the lead to the case before you check it. The condensor should measure infinite or open if it is good.

Thanks again
