coil question

[Gary Davis]

After about 10 minutes of hard running my IH tractor seems to start cutting out. I thought about changing the coil out. I checked the fuel and I have plenty in the tank, at the pump and at the carb. I checked the bowl and carb. jet and found nothing so now I'm thinking electrical. Now for the question: Since I ran a small engine shop, I have a 12v Kohler coil on the shelf. I know that I always heard don't use a car coil on a small engine or it would burn the points up. Common sense would tell me that the Kohler coil would not have the capacity that a 4 cyl IH tractor needs. So I am here with the question for anyone who knows for sure or would I just be wasting my time. I am just as cheap as the next and I do have it on the shelf. Thanks, Gary

It might work for troubleshooting purposes, but I don't think I'd put it on permanently.

BTW, I had the same problem with my H and found the gas cap wasn't venting properly.

A bad coil usually gets hot.

Remove the valve cover and check the clearance on those rockers. If there is not enough clearance, the gap will close up when the engine gets good and warm, and then the valves will not completely close. This will result in rough running, sputtering, missing, etc.

Right know I have a coil for an early 70"s car that does"nt need an external resister on my 1963 Allis Chalmers B-10 w/Briggs 10hp single cylinder, been runnin that way for three years now.
I have never heard of the points problem.

You'll be fine with the Kohler coil on the 4-cylinder tractor.

However, the TRUE 12-Volt 14-SB coil NAPA sells MAY cost less than your cost on the Kohler coil.

The coil will work fine. as long as the vo;tage & polarty is right. There is no reason it should work as good as orignal. I used a GM coil internal resistor on a kohler for years & as far as I know is still running . There isn"t any differance in a coil that fires a 1 CYL & a 4 CYL as long as the Voltage is right .

i bought a car from a guy that did the same thing and a mechanic told him it needed a valve job. all i did was replace the dist cap and drove it for 2 yrs until i sold it

I can't think of any early domestic 70's car that didn't use an external resistor. Chrysler prodiucts used a ceramic resistor and Ford and GM used a resistance wire in their harness. Even when they went to electronic ignition Ford and Chrysler continued to use an external resistor.

WHY waste your time THINKING about it... the NAPA 14-SB coil is so CHEAP it makes 'most all other alternatives a $$$ waste of time!

Check condenser also
