Engine issues

Hi all, me again (Probably fed up of me now!)

So today I hooked up a car battery to the rib and tried to start it. (this is just a spare battery from a neighbours 4WD and not the one I will use)
Basically all the electrics work, gps, fishfinder, tilt/trim, tried to start the engine and it just wouldn't fire up. Attached a video below(Very crude will try and get a better one).

Engine was bought serviced by the previous owner and hasn't ran since, this was about a year ago. Full tank of fuel but might have been sitting for a while.

Any advice on starting procedures for old engines that havn't ran in a while?
Or any problem solving advice?

Engine is a 75hp Mariner 2 Stroke 3 Cylinder.

Thanks,
Jack

No video, so I will start with the embarrassing - is the kill cord connected; and the slightly less embarrassing is the circuit / switch working?

Is there a spark at the plug?
Is fuel getting to cylinder?
Is the choke working?
Have you got the throttle (fast idle) open?
Is it trying to start or just turning over without any signs of running?

Attached video here :P
It had some moments where I thought it was about to fire up but then lost power from the battery as im having to get my mate to manually connect the battery connections as it doesn't have the right connectors.

Where the engine cuts out is where my friend takes the connector of the battery and not the engine

As per Poly... basic checks will narrow it down... my first would be to pull a plug after whirring it over and see if it is wet with fuel or dry.

Did you pump the fuel primer bulb until it went firm, before trying to start it?

If the plugs are dry, it suggests there's no fuel getting through. I'm no expert on Carbed 2 strokes, so that's where I bow out, sorry.
