With all do respect to Glenn in Camino, the Per-Lux Ignitor, Petronics and now the FS have been around for 35 years. Created to run stationary engines 24/7, the electronic ignitions are pretty much bullet proof. Unlike others here, I will admit my FS failure was self inflected due to not following directions. I have used these ignitions in classic cars, a 1942 Chris-Craft, Catalina 30 inboard and four Model A's without any issues.
Mickey Remund (engine builder for Mickey Thompson) perfected the Petronix for Model A's and early Ford V-8's and sold the business to FS when he retired.
As others have noted, call FS for info.
