WD 45 ignition

Hi guys, Im new on here and struggling with mt tractor. I have a 1950ish wd45 motor in a 1950ish cleat track dozer. It started running a little rough last fall plowing snow. I first thought i might have got some water in fuel so i drained tank and cleaned the carb. After doing that it still was not right so i was thinking possible ignition issues.The ignition had been changed over to 12 volt before i got it. I have had it for 10 years and has always ran good. I replaced plugs points condenser rotor and cap and coil. It started right up and runs good for short period 15-30 minutes then it starts sputtering and then dies. I check the spark at coil and seems to be shinny silver colored and not blue. If i take rotor cap off and gently scrape points with knife blade it will fire right back up for the 15-30 minutes. It is like the points are getting build up on them. I have them set at .020 The original coil i took off had been painted over so i could not tell exactly what it was, but looking on this site people are using the NAPA IC14SB so that is what i put on it. I have read on here about needing a resistor or not for that coil. I do not have a resistor in my wiring anywhere and not sure if the IC14SB has one built in or if i even need one? Hopefully you guys can give me some insight on my issue... Thank You

Put the old condenser back in and I bet your point problem will go away. As for the coil you need a coil that says right on it NO EXTERNAL RESISTER NEEDED. Now days buying a new condenser and having one that is good is a crap shoot at best. I have not replaced a condenser in years because so many are not any good.
By the way what Cletrac is it in?? I have an HG42 with and Oliver 60 engine in it

are you getting fuel? need to check for spark and fuel as soon as it dies

It is a HG42 as well, The problem with the old condenser is i already have thrown it away. I have another new one i will try to put in this weekend.

I did check the fuel. I thought maybe my fuel cap was not venting and not allowing fuel to carb but that all checked out good..Thanks

I did not have a socket handy to get a plug out to test spark at plug. I just checked at coil. Not the best check i know. This dozer is at my cabin and im headed back up this weekend to get a better look at it. I will take socket and check for spark at plug.

Another good reason why one should not throw parts away. I throw things like old points etc. into a ammo can or other such places so down the road if I need some odd thing I have it laying around. Have those parts have gotten me out of more then one pickle when something goes wrong and you need to one machine NOW. I bet that WD45 engine in place of the old Hercules's engine makes for a good machine. The factory engine was only around 18HP

Sounds like coil breaking down,after it gets hot.

IC14SB coil does not use an external resistor.

Direct 12 volt "no resistor required" coils such as IC14SB do not have a separate resistor in the can.

12 volt "resistor required" coils should have about 1 1/2 ohms resistance between + and - posts on the coil. "no resistor required" coil should have about 3 ohms.

The difference in resistance is controlled by the type and/or length of wire used in the primary winding, not by a separate internal resistive element in series with the coil winding.
