I do a high gear burnout. I don't start out in low gear. I don't like shifting it's just harder on parts. I don't have any trouble getting them to turn over. Ken, It's the same motor out of the white truck(LBZ) 2100 with me suited up full of fluids. It doesn't spin on the hit it's on down the track that i'm having problems. Listen to the video. I will figure it out or I will take it to someone that will.
Jeff...awesome man....did you play with tire psi at all? They look pretty full in that video.
