Video tuning guide

Its probably an Axial and the MRN likes to move on those all by itself. Thread lock the threads and make the needle flush with the housing. Than add some high temp copper gasket maker to the outside of the MRN. Pack the gasket maker around the needle edges and than top it off with a big dab to cover the top of the housing. Let it dry and it should be fine. Its probably sucking air, thats why you cant get it to tun right now.

hey dude
i had probs with the stock K4.6 MRN noving but once i got it set i was told to get a pin punch and a hammer and then tap the MRN and also the outer collar because when you do this it will move the MRN and then it locks it into place. i have done this on my motor and ever since it hasn't moved but the thread and also the needle needs to be copper or brass and i don't know if it will work on any other motors but the HPI coz dats all ive tried it on

hope it helps
