Oh, playtime is it?
That Bammm, cut, was that the sound of a cylinder jamming solid
and the piston rod going through the side of the block due to lack of coolant? :-?
And as you said y'erself, DN, the operative word is "run".
and I
Without those 4 components the outboard won't run.
Tee Hee, always fun engaging in a battle of wits.
Seems to be a little one sided though... ;D
Back to the original problem now, need to go at it the same way a shop would.
The outboard won't "run". Pop the cowling and look at the setup.
Connect a portable fuel tank with new fuel/mix and different hose.
When you pump the primer bulb can you hear fuel entering the carb?
Does the bulb finally stop pumping and become solid, resisting your squeeze?
No visible leaks anywhere? With the water/flush muffs on try and start the engine.
If no luck, after cranking, pull the plugs and smell if fuel is present in the cyclinders.
Check the plugs, are they clean and dry? Wet and greasy? Covered in black velvet?
Each one indicates a symptom. Clean-dry means no fuel entering cyclinder.
Wet greasy, smelling of gas, probably flooded, carb needs work.
Black velvet and wet indicates running rich and with the carbon layer
is shorting out the spark. While the plugs are out, do a compression test.
Why? The plugs are out and it's a good way to keep an eye on things.
Do a spark gap test on each plug wire to verify the voltage is high enough.
Install new plugs, do a timing check to verify brain box is working.
If spark was ok, then fuel system is probably the problem. Check fuel pump.
check last chance filter, if fuel is in float bowl and not making it to the cylinders
then the carb is clogged or there's an air leak on the intake side of the block.
If the engine was flooded, then the float isn't functioning and carb should be rebuilt.
It's all about fuel, spark, air and coolant.
