ATC 125m

[leroysinclair]

Bought a 1984 atc125m 4 months ago, it has a weak spark but was in overall good condition. I replaced the coil, spark plug, and then the stator, after the new stator was installed it ran great for a solid month then all of a sudden it quit without warning. It has 0 spark now, i tried using the original coil as well as another new plug and no change. I tested both coils for continuity and they're both giving me no reading. Just wondering if anyone has dealt with anything similar, I am willing to buy a new coil but i'm wondering if there is an underlying issue causing the coils to fail?

Thanks!

Howdy there Ghostrider! Seem like you're out of gas, did you check the muffler for spark?

It's hard to tell what's going on with your rig, I usually just give mine a lil "how she goin" to the side of the engine case with a sledge hammer and she fires right up.

I went through an ordeal on a 70. This video explains setting point gap better than I ever could. If no wires are pinched and gap is set correctly then you may have a ign coil. That was my issue a new coil was bad. However chances of 2 ign coils being bad are slim.

Did you check the cdi?

Just checked the CDI with a multimeter, and it is the culprit. Thanks!
