Did what you'd do in that order. I have spark. Only clicked after reading your response earlier how the spark lead wire attaches to the plug and hooked it up no issues.
Added fresh fuel (tank was dry - mixed at 25 to 1 as I was unsure of the correct ratio), primed and pulled and it tried to go but didnt run.
Had a look then at the carb and it leaked when the bulb was depressed and I assume it wouldnt run as it was perhaps starved of fuel if the carb isnt sealed properly?
On the attached image, when the bulb was depressed I'd get a decent squirt of fuel out the left, Then as the bulb reinflated there would be a second decent squirt out the bottom.
Could I grab the model of the carb and if there is a teardown guide / rebuild guide? I will begin searching the internet for the answers in the mean time.
I didnt do much tearing down, I just hit it with some degreaser to try and remove what I assume is decades of crud build up before I remove to much.
