Hi - a little help with identifying my impulse car boot purchase... :D

Its a lucky 7 . Its either a 39cc or 47cc. 39cc has a higher rpm and the 47cc that more torque. Both make roughly same hp straight out of the box. They are easy to mod to get more then double the hp then stock

It's a 40mm engine (39cc), see the flat spot on the left side of the cylinder. Plenty of things can be done.
Looks in pretty nice shape.
