ninja buggy motor
 

I am having a problem getting my motor to run correct, all was great until I had to clean up the slot for the idle adjustment the other day. What are the factory settings for the needles? I read on here that is is 5 high speed and 6 low speed with 1mm opening. Also what is the best fuel to run with these engines?
Thanks

When in doubt... start with the needles flush with the housing. This will be extremely rich - but your always best to start rich and tune your way to the ideal mixture.

this is for the low speed what about hi speed? Or is it flush for both?

Both
