Is there a difference between the black widow backplate and the golden bee? Huh...

Thanks

The Golden Bee had a venturi intake of .062" and the Black Widow can vary but typically is around .082". I have had Black Widow backplates that measured slightly larger than that. If the Black Widow is opened up, it can extract a few more rpm's, but the run can be inconsistent not to mention the duration in shortened. I have successfully used .093" without fuel draw issues on the Black Widow.

Would you recommend opening up the venturi on the golden bee to .070

I would experiment wih a plastic backplate thst is still sold on the market, before modifying a rarity metal backplate unless you have spare ones.

I would verify if you have a single bypass cylinder. If your in need of more power, the more effective way of getting more rpm's is to replace it with a dual bypass. There's a considerable difference between the two.

Thanks guy's, understand. No need to open venturi if the cylinder can't accommodate. And yes it has the stock #2 cylinder.
