you guys are exactly correct, it its a 2 stroke (i couldn't make valve train parts that small)
the igniton is a conventional make and break with a 12v coil from an old suzuki moped and a lawnmower 12v battery, i'll use an old points from my VW
and i will have a dimple on the flywheel as soon as i find a sutable one
Any ideas on a flywheel?
