</font><font color="blue" class="small">( O.K This may be a dumb queston but, I'm gonna ask anyway. This decompression lever, is it the same lever that shuts down the motor? or am I missing something??? )</font>
Like others have told me before, there are no dumb question, except the ones you don't ask. The lever you use to shut down the motor is probably the throttle. It's the same one you have to open up (or pull back some) to get it to start. It is on the right side of the dash. Pull it back to go fast, push forward to slow down, all the way forward to kill it (maybe, might be different for your tractor.) The decompression lever on mine is under the dash on the left side. You don't have to use it all the time to start the tractor, maybe just when it's very cold. You don't use the decompression lever to stop the motor, just to help start it. It will not start with this lever engaged. You just crank it for a few seconds with the lever engaged so it turns over nice and easy (no compression) and then turn it off, and start as the regular way.
Hope that helps, it would help if we knew what kind of tractor you have /forums/images/graemlins/smile.gif
