After much research I decided to go for the Yota carb over the CV and the Webber.
First because of the ease of install. Almost no mods to the Zuke.
Cost. $99 New from a vendor found on E Bay.....
Took 1 hour to do the entire conversion and we were off to the woods for a test drive.
Worked flawless .
Steep angles were no problem. Fires up effortlessly. Great torque out of the whole. Descent top end increase.
I gotta tell you. If your looking for a good swap for that pos Hitachi. Some times old school is best...
You will get better top end from the Weber, But big angles will be an issue.
The CV conversion works great, But at $400 . I don't See the advantage over the Yota.
The carb we used was the last version of the 2bbl used on the Corola 1200cc engine 1978 ish.
NO MODS REQUIRED to bolt in place of the Hitachi!!!!! And using the stock Zuke air box.
Had to convert the throttle cable to ball fitting , and fab a cable mount for the throttle and choke cable. That's it....Boxcar...
