OS. 21 tm
 

Hi I'm a older man done purchased me a toy ( 1/10 scale truck) the carburetor needs to be adjusted. I tried the old Briggs setting all in 1and a 1/4 out. Got it running but just halfass can someone please tell me a good starting place for the jets.. the truck has a OS21tm with a slide 3 jets carb. Any help I will be so great full . Thanks.

Page 22 of the instruction manual details how to set the carb back to the initial starting points. Start the high-speed needle should be at about 2 turns out from closed.

These are rough starting points and you'll have to adjust from there.
