I know the OKO isn't really everyone's favorite as far as a China Girl carb, but I needed a new cylinder after a wrist pin circlip decided to disintegrate and absolutely destroy the bore. Admittedly I didn't look very hard, but the only easily available cylinder I could find was the kit that comes with a modified cylinder, DIO reed valve, and (knockoff) OKO 21mm carburetor. I figured I'd give it a shot and if it didn't work I could always get a different carb, like a Mikuni, Dellorto, or even a 19mm (genuine) OKO.
I've already installed a windowed piston and a replica MZ65, and I plan to add a CDI with adjustable timing, like Jaguar's, so as not to have to mess with the magneto. I've also got a jet kit.
So my question is: Does anyone have any advice with getting these set up, like where to start with jets and timing, or any mods that should be done? As far as spark plugs, I have a couple NGK B7HS (the parts store was out of B6HS); will these work, or should I get some with a different heat range? I'm at about 2500 feet above sea level, elevation wise, and have a 66cc motor.
Also: The carburetor has a nipple on the bottom of the float bowl, with a long hose on it. There's also a barbed fitting on the intake pipe. I'm assuming the two are supposed to be connected? I'm not positive though.
Thanks in advance for anyone's help.
