Many of you have helped on my prior quest to re-start my Yanmar
after adding fuel
(refueling 20gm20f), leading to success after bleeding the system and my great gratitude. During that time I learned that many people run the starter to crank a few turns with the decompression levers on, in order to bring oil
to the cylinders in a cold engine
before high pressure operation. I tried to do that but instead of cranking all I got a was a whirring sound as if only the starter motor
was working. Is that what it' supposed to sound like with the decom levers on? When I then tried to start with them off it wouldn't start, alhought the batteries were low and the engine
had not been warmed due to a drop light in engine burned out. Any insight into this decompression (do it, don't do it, what's the sound, etc?). Thanks again in advance for any assistance on this.
