Hello All. I've been running this engine for a number of years. This year I have had the no oil alarm sound a hand full of times (beeps at about one second intervals). It has only alarmed at idle, never when rpm's are higher. So far to silence the alarm all I've had to do is squeeze the oil bulb and the alarm goes quiet immediately. The bulb is already hard when I squeeze it. Once the alarm goes quiet it usually stays quiet for a number of trips but the last time out this happened twice and I'm thinking it needs to be looked into. Any ideas on where to start would be most appreciated. Thanks, Rick.
