I ordered the Premium Kit, and the inlet elbow. First time tearing into a CV carb, was a bit nervous. No need to be! Between the introduction sheets that came with the kit, and the online videos...........easy-peasy. I took my time, and it was done in less than two hours, if you have been into a CV before, I could see this done in a half hour. Set it up per instructions, fired right up. Finally got to take it out yesterday and start really dialing it in. With the EZ-Just screw, no problem. Snappy throttle response, definitely feels like more power, can't wait to really put it through the paces. Thanks so much CV Performance!
