Chad, Your 2 ninjas showed up today. One needs bearings, the other just needs a resize. I will also like we talked about throw them on the bench and get the needles straightened out for you and get the tune close for you so you are in the ballpark when you get them back.
I will throw in a tuning guide for you to explain the tuning procedures for nitro engines,
Thanks again,
Lance
