Default Cebtrifugal clutch users

I just finished installing a C clutch with a shift kit and everything is working fine. But it is extremely hard to turn the engine over. I have to stand and jump on the pedal to even get it turning and even then the clutch slips after half a turn. I don't even have the carb or exhaust attached yet so I'd think it would be extremely easy to turn. Is this normal? I'm thinking about just getting a pull start if it is. Thanks for any help.

You can't bump start a normal cent clutch, you need a pull start.

I have never seen a cent clutch that only spins one way, what clutch are you using?

There is no centrifugal clutch I know of that uses a one way bearing. In order to kick start it with a shift kit.... well, you couldn't. So whatever clutch you have that has a one way bearing, that must not engage by only the bell spinning, or it may take a lot of rpm for it to happen.

The bearing that connect the clutch bell to the shaft is one way. As far as i know they're all one way. I can spin the output (left) side sprocket with a tool and turn the engine over. Go to 19:00 on this video you'll see what i mean. https://www.youtube.com/watch?v=r2QfzxIEm_Q

I'm not watching that whole 24 minute video to find when he spins the sprocket.
