I am working on my neighbors Coleman generator with a Robin/Subaru EX 30 engine.

The coil was bad so I ordered a Sten's replacement at less than half the OEM price. The new coil had no low rpm spark.

Emailed the supplier and he immediately sent a replacment. I installed the new replacement and the firing is so advanced that it pulls the rope out or your hand. That HURTS. Double checked everything, including fly wheel key, and all seems ok.

Two bad coils in a row. I just ordered an OEM coil for $77 plus shipping.

Anyone else experiencing after market parts problems?

I think about a year ago, I had either read something or it was from a conversation at a repair shop? But I do remember the subject was about new coils being bad right out of the box. Who ever it was said it was a 50/50 shot weather the new coil would be good or not. Good luck on the OEM one. I myself never had a problem with a new coil causing an engine to fire to far advanced.

I have heard that non-OEM coils are going cheap.

 

But I can't see how a coil could cause a premature spark?  The only thing controlling timing is the key, right? 

 

I'm curious to hear how it ends up!

The electronic ignition system built into the coil actually  has an electronic advance circuit built into it. This is the second time I have run across this problem.

The automotive business is just as bad with aftermarket electronics. I prefer factory equipment when it comes to stuff like that. Even then its not 100%. It just comes from a different Chinese garage. It can really make you second guess yourself sometimes.  :wallbanging:

New parts, no matter what brand, are hit-n-miss at best.

What you'll find is that most of the parts come off the same assembly line, just different packaging.

Thanks for sharing that, I learned something today! 

 

Considering it doesn't have points or a condenser, Subaru doesn't cross my shop very much!

After a couple of days talking with the supplier, and the supplier talking with Sten's it has been determined that Sten's does have a problem with their coils. Full refund and they don't want the bad coils back.  Nice people to deal with.
