<HTML> It has been a while since I owned that Spree and didn't remember the air horn situation. As I said, mine had the same problem and that's how I got it fixed. If a priming system is what you need, then that may be the way to go.
The other annoyance with mine was that it was electric start only and if the battery didn't have 13.5168 volts, ( just 13, really) it would crank til the battery ran down and would not start. Hook up the jumper cables and it would kick over in half a turn. Never could figure it out. Not surprisingly, the next year model had both kick and electric!</HTML>
