Re: willieberight and silvertip please help!!!!!
Make sure the oil tank on the motor is full to the point of overflowing. If the oil level drops below the neck, it'll start beeping like you describe. With the motor idling, crack the cap open til oil comes out and snug it back up. Don't overtighten or you can crack the cap.
I'm also concerned for the pump drive gear. If the motor sits a long time and wasn't properly winterized beforehand, the driven gear can rust. The rust will take out the plastic drive gear on the crankshaft and the pump will not pump. That can also cause what you describe as the gear begins to fail.
Check the oil tank first. If that isn't it, mix your gas at 50:1 til the problem is resolved (if you have to run it) to be safe.
There are three sensors. The overheat sensor (one on each head actually) that sends a constant beeeeep if it gets hot. The other two go to a warning module that sends a beep beep beep. One sensor is the oil level sensor in the oil tank and the other is a motion sensor for the oil pump drive. There is no distinguishing by sound which is sending if you get a beep beep beep. You have to troubleshoot each sensor and what it senses.
There is a fourth in EFIs that I nearly forgot about. On the bottom of the spin-on fuel filter is a wire that senses water. It goes to another warning module that lights a tiny red LED on it. That will also send a beep beep beep at occasional intervals. You can unscrew that sensor from the fuel filter and drain the contents, or replace the filter. If your motor has carburetors, it won't have that.
If the warning module itself fails, it'll send ghostly sounds, rapid beeping, or constant beeping anytime the key is on. It doesn't sound like this is the problem, just be aware of it.
I hope this helps.
