Piaggio diesis wont start

[frodmyster]

Hi peeps, newbie here. I have a 2003 piaggio diesis 100 that has been unused and garage since 2005. I have fitted a new battery and have a spark, fresh fuel, cleaned the carburetor out but it just won't fire up. Sometimes it will sound as if it's trying to start but then nothing any advice would be great guys and gals. Neil

A two stroke needs fuel , spark & compression to start . As it's not been used for 12 years it's most likely the crank seals have gone ?
