Newbie here and just purchased what was a running 1996 MZ300.
Collected it, checked all oils, tyres etc, sorted insurance and set off for a spin on the trusty old 2stroke.
Managed about a mile or so changed up into 3rd and then hesitation, smoke, lack of revs and wouldn't pull.
I pulled over it was idling badly barely ticking over lots of smoke and then stopped. I couldn't start it again, seems to have compression though.
Now sat in the shed, fuel seems ok and running freely, any thoughts or ideas please

Thanks in anticipation
Steve
