Greenmech Eco Arborist 150 Won't Start

Logical. The colour of the smoke makes me suspect some sort of air restriction, as a non starting diesel ( eg failed glow plugs ) usually gives white smoke if it's getting air and diesel. I once left a wire off an engine when replacing an alternator, and despite cranking the engine until the building disappeared in white smoke, it refused to fire. 

Is that right? The air hose looks very unobstructed, but I'll definitely investigate.

I'd like to add to this post by saying that I've had problems with dirty fuel since having the chipper. The fuel was actually not making it out of the tank because of a blockage. Also, dirt has definitely made it past the inline filter that I put in it and into the main filter, so I'm still leaning towards injections, but I really don't want to do that... It is the equivalent of sending the young brash dragger to go up and take the top out of a 150ft fir... Still got to learn somehow I suppose

I saw something the other day a little like this. It was an air hose collapsing when warm. Doesn’t feel like a slam dunk answer to your particular problem but something to consider. 

 

 

 

Covers it in the first nine minutes.

I've not started drinking yet this evening. Greenmechs are still shit though.

It's not unknown for air inlet hoses to collapse as the engine cranks. Unlikely, but not unknown. Something in the recesses of my mind says that some old Bedford lorries were known for this. I see AHPP has suggested something along the same lines. We don't have the engine in front of us, we're just theorising of course.

Well I appreciate the time taken to write replies. I have ordered some new injectors and glow plugs, as they add up to about £110 for all of those, which I think is pretty good. I'm now convinced it's a fuel issue and not an air issue. I'll let everyone know what happens when I get it fixed, so that this post has a resolution unlike a lot of other ones.

Well I like mine! Not bad for a 2004 (I think) and it's only engine trouble. Looks like the most straightforward engine in the world so I'm pretty miffed that I still don't know what the problem is!

Good luck with the injectors. Daunting job but £110 will be cheap ruling-out and mechanical education. Unless you mangle it. And what's the first rule: Don't mangle it.

Looking at it, they are mechanical powered injectors so shouldn't be too bad.

 

Real question is why the fuel is getting dirty and keeping it clean in the future, how often are you replacing the filters ?.

 

Where you keeping or getting your diesel?.

Honestly I don't know why the fuel is so dirty. Possibly the tank is deteriorating or something, but there's always visible dirt in the inline filter. I fill up at petrol stations.
