86 ER 120 no start question.

[Cudos]

I had to be towed back after I stopped to fish but a minute later decided to move. She cranked but would not fire with or without choking. My question is should I have been able to pump the primer bulb to get it hard? I tried for a minute and it was still soft. I cranked her for about 5 minutes of and on with no luck.

After we were towed back 15-20 min had elapsed. I tried to start and it went with a little fast idle help. Now today it seems fine. Could it have been flooded? and should that bulb not have firmed up when squeezing. My first thought was that the vro fuel side was shot. Also, just to add. If the VRO oil flow quits will the motor start or just turn over. The reason I ask is that just as I entered neutral to shut it off I heard the buzzer (warning horn?) its after that that it wouldn't start. Will the motor start if the VRO dies?

Any ideas?

Cheers

No oil,that sensor probally shuts down the motor when activated being that the engine would blow fast with no oil.

It does not shut off the engine. The buzzer could be alerting to a fuel restriction or loss of fuel pressure.

A bit premature to start thinking faulty fuel pump.

The primer bulb should stay firm all day. If you pumped the bulb and it never got hard, it's either leaking fuel or sucking air. Or the bulb itself has gone bad.

The bulb pushes fuel through the pump and fills the carb bowls until the float valves are shut, so even a faulty pump won't stop you from pressurizing the fuel line. Unless fuel is leaking out of the pump itself.

Listen close for a wheezing sound at all the fuel connectors while you squeeze the bulb. Those quick-disconnects and primer bulbs will wear out eventually.
