The engine also has a hard time idling and will stall. i guess my main question is... could too much oil/small air leak cause the motor to not have any power/torque whatsoever?

what was interesting is that when i would pedal assist really hard, the rpms would go up and it was able to maintain a fairly high speed.

any thoughts are appreciated
