yd100

I’ve been running my YD 100 really good after breaking I was using 32 to 1 all of a sudden I get power loss I tried changing the carburetor tried changing the fuel from 30 to 142 to 1 checked for air leaks clogged up any leaks but I still have all the loss of power I have good spark it’s lost...

Went for ride around the Area today. Figured I post a video of the Yd100 ripping home down the dirt trails.
