Figured out 2 issues this week, the starter on the motor was low torque starter for a lower compression motor. My starter guy said get a new better one so I do got a high torque starter from him, put it in there along with a new tci flexplate. It whips the motor over awesome and has no kickback at all.
Today while racing it started right up everytime with no issues all day, best starting I've ever had with injection started like a carb. I had no idea the starter in there wasnt meant for it, its a starter I've used several times in the past.
I also figured out why the motor does start on the primer, I opened the butterflies on the terminator had my dad hit the primer it shoots a straight stream straight across the intake and down the back to runners. I think this could be apart of why I cant get it to start on the primer without kickback. I need a primer plus spray bar which I will have on there soon.
thank you guys for all the help ! If I have any more issues I will go back to the drawing board with all the input from you.
