Replaced clutch, low starts fine, high feels like it’s trying to start moving in 3rd gear. High, low, neutral and reverse are the gear selections

 

I would guess you have assembled the variator pulleys incorrectly and the front pulley is not going out wide enough, or the back not going in far enough.

 

literally popped off the nut, removed old clutch, put on new clutch and put nut back on. Front pulley wasn’t touched. Reason for replacing was the weight springs had fallen out.

 

The word clutch has been misused by makers of variator drives for a long time, so I have no idea if you are referring to the clutch, which is centrifugal, or a variator pulley which makers insist on calling a clutch, but isn't. Either way, the pulley assembly and belt would have to come off and the rollers inside the pulley assembly could have got "out of bed"

 

reason for replacement was clutch weight springs falling out, so I’m sure it was the centrifugal clutch. The variation pulley is the front one, it wasn’t touched more than getting the belt off, I compressed the clutch to make the belt drop and become loose enough to slide over the front pulley.

 

There is another set of centrifugal weights, in the variator pulley, depends on design but, with no belt to hold them in place, some may have got out of their channels, so stopping the pulley from sliding in and out properly. Worth taking a look at it.
