I have bought a novarossi p3 xs serpent engine. I have put it in my hyper 7 and i broke it in with factory settings. Then i took it to the shop and he tuned it to 16% all was fine but i tried to start it a couple of days later and it wouldnt idle and kept cutting out after 2 seconds. If i gave it some throttle it would stay alive. I gave it a good run like one tank and abit and it had an extremly high idle and just wanted to keep moving without applying the brake. I know this aint normal so i cut it out and looked at the glow plug and it was black. I have looked at tuning guide but i cant seem to get it right. I can ever get it so judders on idle or high rpm after a run and wants to take off if lifted up. Can someone point me in the right direction please thank you.
