I'm new to engine tuning and could use some help from you experts. I recently aquired a used nitro 4-tec with a trx 15 engine. For the life of me I cant get the thing tuned right. Either it hesitates when i squeeze the throttle or it flat dies. Could someone fill me in on what the factory settings for the idle and high speed mixture should be. At least give me a place to start. Maybe some tips on setting both correctly. That would really help. Thanks.
