I had an intake valve go bad, and it was all the same symptoms. Just get an ebay head for 30-40- bucks, and be sure to ask the seller FIRST if it has steel valve seats. If not find another

OK local shop just got back to me, low compression.

As I'm off on Business next week and taking her to and from work costs about £8/day more than the Scoot I'm probably just going to suck it up and get them to fix it.

No, guy who collected said he thought it turned over a bit easily (It's always been quite easy, first and only 50cc I've ever worked on so assumed it was 'normal'), they ran a quick comp test and its come back very low (didn't ask for a value), they'll probably have the head off later today or tomorrow.

i still reckon there will be a problem with it even after they try to sort it. i had the EXACT same problem with my scoot. everything checked out fine compression wise, but it was the diaphram in the carb that was letting it down, somthing had happened to the diaphram so the slide wouldnt work properly hence no fuel getting to the engine and it constantly cut out. when i fitted the new carb i had no more probs with it and it ran fine. if you were to get a new slide and diaphram i bet it would work a treat.

mine looked in top shape when i had the carb in bits but the slide wouldnt work and the bike still wouldnt start. which would suggest that the diaphram wasnt working properly.

Rings piston and bore shot, rebuild cost horrendous so will have to look at DIY I think, how hard is it? Any ideas where to get a kit from UK?

8500 miles (about 13000km) did come with no air filter and had been messed with but seemed OK, apparently had run low on oil yet it had only done 130 miles since I topped it up so can only assume the rings were on their way out and it burnt it all!

Think I'll get it back and get that kit if people think it will fit OK....

Yes, seemed to run OK, not burning oil (visibly) and told it had only just fallen off...

So will that kit fit and will I need new mains and possible crank do you think?
