The carb is fresh and clean. Just cleaned and installed last night.
While pushing it backwards, you can hear every thing in the crank moving around, but I can't say its the same sound I am experiencing.
Transmission oil was changed a few days ago. I put in 500ml and there are no leaks but I will check its level later.
I've never had one of these things, nor heard what they sound like. Maybe it's supposed to sound like this?
