has'nt run for a couple of years, drained old petrol out and cleaned carb out. Engine starts but dies almost immeadiately. Done this too many times now any indicators as to where to look for fault please.
Well done guys, turned out to be a blocked jet, cleaned it through and hey presto. Starts first time and runs as sweet as a sweet thing. Matt bought it as a runabout on the road, its a 125cc Yamaha RD 2 stroke of 1985 vintage. Memories are a cloud of blue exhaust fumes
