Ok Update....well got sealed bearing and it fits... the gearbox installed with an extra brace ..idea came from the Henisun..150....but mine comes off the top of the gearbox..then to the lower motor mount.....then cause it has set for 2 years....i had to take off the carb.....broke a little plastic taking the front end off....but the carb was nasty....all clean...and back on ...now it starts on the first fire...attending to the plastic now with some JB Weld...see if that works......As for the gearbox....not under a load it seems to run pretty smooth now....for how long thats the real question...
The case that i fixed with wood screws...notice sealed bearing.
Full of grease.
Installed with extra brace.
