Tecumseh no spark

Tecumseh ohv 130, replaced coil, spark plug, checked all clearances, no matter if safety switches plugged or unplugged still no spark. Any ideas?

Since I only use OEM coils I haven't seen this problem; yet.
 
If I do find a defective new coil upon installation the vendor better replace it especially since I am in the business of repairs. No excuses for selling a defective product and not willing to replace or credit the purchase to professional shop. I understand that vendors try not to cover defective products but when a professional mechanic installs a product he usually knows what he is doing. Plus there will be bad products from time to time; no product is 100 prefect.
 
Here is example of an electrical item that failed shorty after install this year, I mean with minutes. Kawasaki aftermarket voltage regulator. This was customer trying to save a few bucks on a repair. I ended up installing an OEM voltage regulator.Since I had to have the job out the next day I had to obtain the OEM regulator locally and sold at cost.
 
I called my vendor explain what happen and that the OEM replacement was working correctly. My vendor had no problems crediting me the cost of the regulator. Of course I have been buying parts from them every since '09 with only a handful problems andeven through had only purchase $1.500 in parts in the last year from them. My actual parts purchases last year was near $10,000 from all my vendors.
