Maintenance time - engine rattling

Pics tell it all. Starting to hear funny noise from engine, rattling at normal, high pitch at idle up. open up the back plate n wah didnt know so bad til WY told me. Time for some maintenance after almost 9 gallons through the TT50.

More pics to come when i dissemble the whole engine. Well at least i managed to try out some full autos today before this downtime.

Brownish crankshaft. Bearings looked rusty as well. Haiz
