Ok My turn to ask.

That 1066 that I bought out in Nebraska starts great.

Here lately a couple of times after it started it died. (lack of fuel)


If I work the trottle and keep the rpms up it will stay running. But who wants to rev a cold engine.


It will start back up and run fine. One time I had to pump the primer pump to get it to go the second time.

Question; Is there a check valve on those pumps or where might I be loosing fuel or grabbing air?

Don't think it is sucking air or it would do it while running wouldn't it?

Darn thing has all the power it needs after it has run for 10 seconds or so.

Hey Bud!

Did you check those little hoses/end plug on the injectors?

After it is up and running, will it idle okay?

That just sounds like it's pulling air back in when it's not running. If it were starving for fuel, it would act up running.

Also, have ya looked at that air cleaner?

Allan

Yep air cleaner is or was OK in April.

As much rain as we have had not much dust to plug it since.

It idles fine after 10 to 15 seconds and doesn't miss a beat the rest of the day.

Are you talking about the return fuel lines?

They may be bad and allowing air in. I replaced them all when I got it but that doesn't mean there ain't one bad now.

Or is there another plug there that I am not familiar with?

You have a leak somewhere between the fuel tank and the charge pump on the back of the injection pump. It may not be great enough to leak fuel but it draws in air when it is running. A tiny leak will not let in enough to have much affect on the engine when it is running because the pump is able to keep purging it back into the tank. When the engine is shut off the air collects in larger bubbles and when that gets in the pump it can cause the engine to die.

If you have not already done so, change the primary fuel filter. The primary filter has a vacuum cause by the charge pump drawing fuel through it from the tank. The secondary filter is under pressure from the charge pump and should not allow any air into the system. A dirty filter can cause the charge pump to create a larger than normal vacuum in the system which will draw in air at a poor connection. Inspect the fuel lines for any worn spots. A worn/cracked line may allow air in before you see it leak fuel. Tightening the fuel line fittings may help but there is good chance that the seal rings have gotten too hard to keep a good seal. If changing the filter makes no difference I would also install new seal rings.

Another possible leak location may be the charge pump itself. A worn hand pump seal could allow air to be drawn into the fuel system. A worn seal on the pump drive shaft usually causes fuel to enter the crankcase but it may be possible for air from inside the infection pump to be drawn past it.

Those inj. pumps have a system that retards the timing and richens the fuel for starting. As soon as there is oil pressure it goes back to normal. This is fairly common characteristic of them. Just set the throttle up a little more and see if that dont help. Roy
