[GreenKeys] Model 33 CR LF

[Troy Peterson]

Hi Everyone,

Here's a video of the carriage return problem:
https://www.youtube.com/shorts/6BkMjAAqsqo

You can see that it returns very slowly and when I type 'W's it doesn't 
actually engage and move forward until the fourth keystroke, so the 
first 3 are overlapped on the page.  If I compress the spring a little 
by hand to make it shorter then it returns with much more authority and 
engages... I've checked and lubed everything I can see and the carriage 
seems to move pretty freely to me but maybe there is still something I 
missed and it's not free enough.

Cheers,
Troy.
