Andrew, I plan on fabricating a tab with a small platform at the base and drill and tap for two #4/40 screws to secure it in place..
This tab had been broken off sone time in its previous life and they had wrapped the shaft with wire to keep the float from sliding on the shaft and rubbing on the chamber. But this let that end move up and down, that would allow the float level be constantly changing.. Some people,,,,,,,
I will come back here and post info on the progress on this issue.
As far as some ports getting clogged with the media I will be blowing everything out with compressed air and flowing cleaning fluid through all ports and passages.
Thanks
Paul
