Buy a pos if you want to. It's your money. Here's the one I have.
Rusty, you have a 50+ year old timing light. They don't build them like they used to and good luck getting that old antique fixed when it fails.
USA Vintage Balkamp Timing Light Sturdy Chrome 6 12 Volts | eBay
Was given to me by my auto shop instructor in 1983. He owned it since the 60s. It's hands down one of the best I have ever used.
Two things about timing lights. 1) Do NOT get a dial back piece of crappola. I don't care who makes it. Too much room for error. (End of quote)
Your opinion on the advance "crappola" I'd like to see some lab tests on the accuracy. I would trust a digital advance more than a dial. The dials are just attached with a set screw.
2) Do NOT get a timing light that the wiring harness unplugs from the gun. They always work loose and fail to make good contact. (end of quote)
Anytime you use a timing light the engine is running and the fan is spinning and the cord is always close to the spinning fan blade. The manufacturers designed a lead set to unplug so you can replace the pick up and cables without taking the light apart.
Don't waste your money. Get a good old, heavy METAL RELIABLE non dial back light. You'll be glad you did.
