Evinrude 130 fuel problem
 

I went to start my engine yesterday and noticed my fuel bulb had lost its prime completely. I removed the water separator and it was empty. Removed the fuel line from the tank, covered the hole and pumped the bulb, I felt suction so I put it back together.

The bulb is primed and fuel is in the carbs but I cannot get it to run. It will fire momentarily then shut down.

I have never had a problem losing prime and it was just ran about 2 1/2 weeks ago.

Could there be a problem with the fuel pump. What could cause a loss of prime then a no start condition? It is almost as if it is out of fuel (there is plenty in it).

Is it a possibility that there is water in your fuel???

Definitely not, fresh gas is in the tank. Water separator was drained and clean.

Might be the VRO pump..That happened to mine. It seems that the oil and the fuel both pump through the VRO. At least on my 86' Johnson.

sounds like a bad primer bulb.

check the fuel conenctor on the engine, it may not be all the way on, it may look like it is, but pull it off and put it back on, making sure its goes all teh way, also make sure it goes on the correct way, some of them will go on either way(don't ask how I know these things)

It looks like I will be pulling the heads. I just noticed a milky substance on one spark plug. I plan on doing a compression test first.

Just finished the compresion test, 125-135psi except the cylinder with the water mix had 50psi.

you may get lucky with just a new headgasket or it may have either a hole in the head or the cylinder wall.

Pulled the head yesterday, cylinders appear great. Still see the crosshatch pattern after 600hrs. Head gasket obviously bad. A new one will be here in a week or so. We will see after the install.

Got the gasket in today so I installed it. Amazingly everything appears to be good to go. I started the engine and let it warm up to temp then did a comp test. Back to 125psi on the now not milky cylinder. I ran it for 30 or so minutes in the yard then did another comp test.

Looks like I am lucky.
