@DannyP posted:@edsnova get some 7/32" brass tubing and a 5mm die. Screw them in with a bit of RTV and you're done. If I was going to use carbs I'd do it that way. But honestly a TPS works just as well for load sensing advance adjustment. That is if the black box allows that.
Be ready to tweak your throttle linkage if using the CB vacuum kit.
It doesn't. It would be great if it did, but no.
I ran a Black Box on my twin-plug engine and am an enormous fan. The interface with the computer is archaic, but the digital advance works fabulously.
Regarding the MAP vacuum load sensor - it's neat, but certainly not required. I'd never let an inability to get vacuum stop me from using the box. As a matter of fact, you'll do a lot better just setting up the curve without any vacuum advance until you get the hang of it. Trying to map for load on your first time out is a bit like drinking from a firehose.
Even if you never use the vacuum, your spark will be 10x more accurate and infinitely more adjustable than with any Chinese distributor.
