Since there seems to bee no fuel tap, the probable best way to drain the fuel before replacing the line would be just to pull the line off and drain it into a big coffee tin or glass jar until the tank is empty.
Had just filled it with about 1/2 a jerry can - have drained it back though Its very possible that the oil being overfilled will make it smokey, I have seen this case more than once
Me too that was my thoughts ( and hope )As for the slow starting, I would imagine either your starter motor or battery is tired, it could even be the earths/ connections to the starter are dirty.
Probably the battery - had it on charge overnight - but it quickly lost umpff - has been idle for 2 years so I was told ( little old lady never used it after her husband died)
