76 DT400 performance was created by adguy2112

I recently installed a VAPE conversion on my DT400. Timing should be spot on and it has plenty of power on acceleration. However on deceleration it bucks almost violently. As soon As I accelerate it seems great. I’m wondering if it caused by exhaust back pressure or what else I should consider. Timing is set at spec 2.9mm btdc. It also has died at a stop occasionally.
