Can't tune engine

[RS4 Owner14]

So my nitro engine is causing me some troubles its a new engine and when ever I turn any of the needles ( LSN HSN ) it will start up ad when im driving it I will pull the throttle and it will bog down and die. Its at factory settings and I can only run it at that. The temp is at 270 which is way high and its rich. Any suggestions?

Factory settings are only a guide as a starting point in tuning.After that you must tune to air temperature and what type of nitro fuel.You need someone who can show you how.

Plus as the temperature changes thru the day so you will need to re tune again.If you don't re tune that motor won't last long.
