Looking for Help in the Portrush / Coleraine area (from practical DIY mechanic type)

Have just had an email from friend who lives just outside Portrush (actually on the NW200 course if I am not mistaken !)
Her young son (about 10/12 ? ish) has a "buggy" ... bought near new a few years back (so it's not a dog !)
Buggy has died , and she is looking for some one to bring it back to life. (I would go myself but a) am an hour and a bit away , and b) am off to London tomorrow for 5 days !)
Could be (likely to be) something really simple - fouled plug , ropey kill switch , blocked air filter , dirt in fuel system ... type of thing.
Without being rude - no-one at the house has a clue , no tools , etc

Would anyone like to help ? (I have no idea what breed it is , but would guess it's a Briggs and S. type engined thing (no brain and a simple carb ?))

PM if you can help , and I'll put you in touch

cheers

Alan

Sorry I missed this Alan and me in the north Antrim area yesterday servicing a bike. I'd have had a wee look at it. Apologies.
