hey guys,
im totaly new to nitro and bought a vulcan non se, i ran it in for 3 tanks and then gently for 3, since have almost run thought a 1lt of 25% nitro fuel. now i cannot start the car, and if i do get it started it stalls when load is applied to the motor and cuts out, then wont start. i have a feeling my bro played with the settings. i dont know what is high and low etc, i can only see 2 screws the one that is sort of attached to above the fuel nipple and the one under it with the spring. can someone tell me where these 2 screws should be set.

cheerz matty
