For those playing at home kz1000st was very close. It was a cracked piston. Thanks to everyone who contributed to this thread for your help.

Just an update. Replaced Crank Seals, they seemed Ok, but replaced them anyway since everything was apart. Won't start at all now. Spark is still good and fuel seems to be getting through to the cylinder Ok. Will probably go one step further and replace piston and rings.
At a bit of a loss at the moment, and pretty frustrated. Thanks for the ideas so far.

Hi all, I wonder if anyone can help me? We have an Adly GTA50, 49cc 2 stroke. It has approximately 12000kms on it and has served us well. However recently it displayed a problem that has me stumped. When it is cold it starts and runs great, however once it is turned off it simply will not start again until it has cooled down and sat for a while and it starts and runs great again.
I have cleaned every orifice in the carb including the starter and pilot jets a few times and replaced fuel lines and the fuel filter. There is plenty of spark and the plug isn't wet when it won't start. Today when I was playing with it I discovered that it will start when it is warm if I plug the air inlet on the air filter, basically flood it then unplug the air inlet again and turn it over for a while it will start again. I'm thinking that maybe there is a vacuum leak somewhere but can't find or think of anywhere that it might be.
Any suggestions? Thanks for reading.
