What motor is this?

Just bought a 1980 Aussie Ex-Mod Series III. The original diesel motor was replaced in Australia in 1993 with this motor. Can anyone tell me what it is and how in the world I adjust the carb on it?? It runs both petrol and propane.

To be specific the picture is of a Euro Intake-Over-Exhaust (I-O-E) 2.6 liter 6 cylinder engine.
The picture doesn't show the carb very well, but it looks like a Stromberg 1 3/4" side draft.

Before you do much with the carb, it is best to make sure the diaphragm is not torn or split.
These carbs work really well and are fairly easy to adjust provided the float moves freely, the damper is filled with oil, and the needle is not bent.

When these engines are in proper tune, you'll never witness anything smoother.

Yeah once I was able to get my hands back there I realized it was a bit different than originally thought. Looks like the Stromberg. Click image for larger version

Yes that is the Stromberg.
If you send a message to JOE CURTO, INC. he can either help you if you need parts or direct you to where you can get them.
Joe Curto mainly deals with SU carbs, but often has had Stromberg parts in the past.

I have a pretty extensive cache of parts and may be able to help as well.

DO NOT confuse your engine with the NADA 6 cylinder engine.
It has a Westlake cylinder head and an engine very different from yours.
While they look similar and many parts can interchange, please understand that your Euro-6 is very different.

After a quick google search I'm left feeling a bit scared about my future relationship with this motor. Seems like a lot of folks aren't a fan and parts are hard to come by.

Basically the problem I am having is that after running a few minutes in 4th gear at a constant rpm, the truck will sputter, back fire, and lose power. Sometimes it will outright stall, sometimes it won't. I pull to the side of the road, wait a minute, pull back into traffic, the truck acts fine for another minute or so and then does the whole routine again. It starts strong and fast and sounds fine at idle. Thoughts?

Also, more back story. The previous owner apparently only put 91 octane fuel in it. I didn't know this and filled my first tank with 87 octane. Don't know if that could be effecting it ... I'm just working through all this in my head and it's too late at night.

I wouldn't change the timing just yet ( ... Look for fuel delivery issues ... Filter first, then pumps ... Dirty carb ... If it runs at lower fuel consumption levels but has problems higher then make sure you've got good reliable delivery.

When you come to do a tune up ... I bought a Craigslist snap on oscilloscope for $150 ... It would be ideal for checking the timing very accurately, gauging appropriate spark plug gaps, checking the state of coils, leads ... All that stuff. One of the best tools I've ever bought!

Yeah check fuel first but it could be that the coil or condenser is getting hot and the spark is breaking down. An indicator of this would be if it runs ok when the engine is cold.

I found three spots it seems the fuel passed through. The 1st is a facet posi flo pump and the next two are filters? Is that what the 2nd big thing is?

middle is a filter, that third should be the flame arrestor on the carb.

Put a 1 3/4" SU on it, far less trouble that a stromberg.

Thanks guys! Problem solved (I think ... Fingers crossed). I just replaced the fuel pump and all seems to be fine on the quick drive I was able to take.

Follow up question (sorry I'm such a newbie to these Series rovers) ... What type of oil is best in these euro 2.6 L motors?

Whatever, it pours it out as fast as you put it in. You should get a green bible, must have for series ownership.

Since you're in socal and it rarely gets cold enough to warrant thin oil I'd go with the Shella Rotella 15W-40 conventional oil. Designed for diesel motors so it has a higher zinc additive package than standard gas motor oils.
