you can run it in as far as you can get the jambnut back on it doesn't really help the power maybe just a touch of throttle response it pushes on the diaphram like it has boost already if you take that out and turn the cone 90 degrees usually where the deepest angle is facing straight to the cab will give you a little more power

Mine has a lot more smoke when you start it, more when you slam the throttle down from a dead stop, and will barely break the back tires loose from a dead, which I thought was pretty good. If you hold the break a little bit, it'll melt the tires
