Installed new 10.4 sheeves and used the same helix that came with sled 40/34p and green spring. Also new rock rollers and went with a carlisle belt. Well now whenever the is under load it falls on its face. Almost like your hitting the kill switch. Extremely bad when you lay it on its side. Seems the worse when on its right side. It's the same setup that it ran fine on previously. More spring pressure cause it's not back shifting? Or is it something else that just happens to be going out? It also started backfiring on start up? Apv valves? Servos? Any suggestions would be great!

More often than not the safety switch quits working because the throttle cable is out of asdjustment.
