Kryptyk,

I am not sure about links or even that specific motor.. If you cant get her running properly, have you checked all the obvious things? Is your plug good, do you have nice clean fuel lines and tank? take the needls out and make sure you dont have any clogs in the carb?... Once you know all that I would look up the factory needle settings and go from there.. Keep in mind the weather and altitude will effect how you tune your motor..

Myron,

Cheers yeah I have done all that it is just the tuning I am having difficulties with, it's idling good but when I try to give it some throttle it just chokes up, I have put through 3 tanks of gas, I just need to fine tune it a bit more...thanks for your help...

Does living next to the 'sea' make it impossible to start a nitro engine ?.
At the moment I have no luck with My Hotbodies .46 , and other things !, and there is no 'link' through HPI to cure my HB .

KRYPTYK,

Sounds like your low end needle is off.. Try opening it up a little...

Spanked Chrome, Sea level does affect your tune humidity and barometric pressure and all.. Try an OS #8 glowplug in the .46, they seem to be the best over-all plug for that motor (at least for me)...
