BEFORE YOU ATTEMPT TO "DIAL IN" THE CARBURATOR, GO TO 24:1 OR EVEN 32:1 FUEL TO OIL MIX.
To set the needle, remove it from the slide, and move the clip up for a leaner setting, down for a richer setting.
The throttle cable should be just free with a fractional amount of free-play in it. Adjust it at the top of the carb.
Grubee's home page says that standard sprocket for this engine has 50T, so this one I have.
Seller told me to use 16:1 fuel to oil mix during first 500-600km. Is this wrong? Should I use less oil?
