Matt repairs a water soaked Onan generator; Yes he was able to make this run

 It is very fun and educational to go through with repairs of Matt, making almost junk equipment run agian  This time it was a water soaked Onan diesel generator.   It was really water soaked:   the air intake filter was filled water; and so with its oil, its fuel tank, its fuel, and fuel lines.  Even its internals.

Matt showed us methodically and patiently:

1.  How to power up batteries and the starter;

2.   Removal of water from the air intake

3.  Freeing the engine from water lock (opening exchaust valve vie the hims on the tappet to open the exhaust valve on compression stroke to vomit out water in the cylinder.

4  Removal of water from fuel tank and lines.   (Cranking up the engine after cracking up the bolts of the fuel lines

5.  Changing oil and replacing the filters

6.  Getting the engine to compress the fuel for ignition

And then success

VERY INFORMATIVE

Stale fuel causing engine failures

 In my review of videos on small engine repair (of lawn mowers) it was mentioned that common cause of engine failure was stale fuel due to winter storage.   It was mentioned that fuel should not be allowed to sit down for not more 6 weeks (60 days others say).   All of sorts of things happen to fuel:    water, some additives solidify, dirt ingested into the fuel tank.  

Such rubbish could be ingested into the intakek manifold and ultimately into the cylinders which could cause engine not to fire or stall.   

So after the long winter, or after long storage you have to spill the fuel and replace this How?

    1  By tilting the eninge?

    2  Or draining the tankk and carb?   (open the dome and bottom.

To solve the problem and go around stuck carb needle, lift the mower (the walk behind)  up.   

The old Volvo mechanic advice on gasoline engine repairs was right and his advice is forever!

 Several decades ago we had a gasollne Datsun and when it conked out at Carebi I had the chance to call a mechanic around, a Concrete Aggregates specializing in Volvo machinery who obliged to repair the old Datsun car.  He said that so that I will save money and so that I will not disturb him (he is being petitioned to work at Canada for Volvo Canada) I should remember two things:

    When a gasoline engine conks out there are two possible sources:   fuel line and electrical

    1,  For fuel

         1.  Is there fuel in the tank

         2.  Is the fuel of good quality (like its not stale, no water or dirt, other contaminants?

         3.  Are the fuel filters:   inline or main filters functional (they could be blocked) allowing fuel to pass through?

        4.  Fuel lines:    are they clogged, kinked or allowing air in the line?

 2.  For electricity:

      1.  Is there electricity coming out into the spark plugs?

      2.  is the coil functional?

      3.  Is the breaker working?

      4  Is the spark plug working

In many of the repair videos that I watched today on small engine, lawn mower repair, these kept being repeated as a meaningful advice
