Make sure you use your screw driver as a lever on the fly wheel first and turn it backwards to get the piston away from TDC. Make sure you
have plenty of fuel at the motor before you start turning it over cos you don't want to be turning over a new motor dry. Not good.
Even use an eye dropper to put a few drops in through the plug hole won't hurt. More lube better.
Thats why i got 5 kids. nah. As every one else said use plenty of heat and away she goes..
Happy running in.
