BBAfS, let's go back to basics...

The 'thing' at 35 seconds in the fuel tank (you knew that) with the carb behind it - that bit's important and we'll need to come back to it.

At 45 seconds you have the engine 'stop' switch - when you flick it to the left so's it touches to the top of the spark plug, the leccy is grounded so the SP doesn't spark any more - so the engine stops (The video would have been more funny if you had been able to start it up - and then couldn't stop it...).

At 1.04 you have the speed regulator - that's basically an automatic throttle and keeps the engine running at a fixed speed regardless of whether it's empty or full of mix. Stop flicking that thing...

At 1.25 you have the 'choke'. This enriches the fuel mix which is what you need when you start it up from cold - like now. And when it's been off overnight - perhaps even over lunch.

So, try again as you have but (a) make sure the STOP is not against the spark plug, and (b) the CHOKE is pulled out. See if that makes a difference. Try it as good half-dozen times. Listen for a change of response from the engine - at the moment it is completely dead, so listen for the odd 'cough' in response.

If it does start, then push in the choke as soon as the engine starts to stutter - it should then run smoothly enough.

If this doesn't work, then you need to get intimate with the SP and the Carb.

First the carb - look at its underside and you should hopefully see a part that's 'bowl'-shaped. See if it has a drain screw in its bottom or around the bottom edge. If so, release it and allow fuel to trickle out - collect this in a bowl and see what state it's in. See if there are water beads at the bottom.

Ok, after a few seconds - when you are sure fresh petrol is coming out - refit the screw.

Next the SP. You'll need to undo this using a special spanner and then lay in on the top of the engine block with the lead reconnected and making sure the SP body is making contact with the engine block. Get someone to stare at the SP 'gap' and see if it sparks when the engine is cranked.

(By the way, don't touch the bare top of the SP when cranking or the engine is running - it'll be a very big OUCH.)
