As I think others have said, there should be a lift aside catch on the pump slide to enable the pump to over fuel to help start-up. Looking at your pic its the bit with the bolt on it.

Yes, that looks exactly the same as the AV1. The block with the bolt through it should pivot upwards. I presume on start-up it will drop back down. On mine I have never needed to do this (but then mine probably hasn't ever had an oil change either...)

If above advice fails, wrap a strap round it and pull strap with another vehicle. Be careful, good guide video on YouTube. 

Saw that on YouTube. Unfortunately the framework is in the way or that would’ve been my go to option [emoji1303]

Can’t you tow it?

Used to have one the same. was a knack to starting it.
Something like this
Decompression up. pump slide up.
Crank up to speed. drop compression. keep cranking till it goes. I could always do it. others couldn't.
You may know but when you hold the crank handle make sure your thumb is in the same direction as your fingers, not grabbing it like your making a fist. have heard of some serious thumb damage from holding incorrectly.

Do you mind if I ask what it cost you?

I've always fancied one of those little 2wd dumpers for the garden, unfortunately haven't really got a steep enough hill to park it on!

Bought this 1973 era dumper yesterday, which of course was running on arrival

Sweet running and idling thing with bags of compression.

I’m not some weakling but I’m buggered if I can start it from cold. There’s zero smoke exiting the exhaust after breaking out in a sweat so I’m assuming there’s zero fuel getting into the pot.

On gravity there’s fuel to the pump, and fuel dribbling out of a loosened injector nut on hand cranking with the decompressor engaged.

I suspect there’s a way of setting up the throttle and enrichening her to encourage a start but am unable to figure it out.

Im sure there’s a few older people on here familiar with this type of machine and wonder if you could give me some tips to be able to start her?

 

Does that block with just the bolt stuck out of it not lift up ? i have a saw with that set up on it and the block flips up and is a cold start, push the trottle forward and lift it up...

Good point. It’s there, but unfortunately the plate it’s supposed to bear against is missing
