Re: 049 Black Widow tuning

I have two late Black Widows (plastic tank) with cylinders marked 4 and open exhaust ports, but a single booster port. According to this thread, https://www.coxengineforum.com/t4022-venom-cylinder they are venom cylinders(?!). Purchased second hand, these must be pieced together. Another unused BW from the same lot appears normal.

When I find my other box of cox stuff, I should have 3 or 4 BW, i will report what cylinders/ect. Only till a month ago, did I know there were different cylinders, lol, been out of it for 2+ decades.

Both these pages say something different on the BW cylinder. Who know how many times they changed stuff over the decades/companies/etc. Very Happy

At least we have some ref.
