Hi Does someone have a complete manual for the 15cc engine? I'm glad i read this forum, would have never thought to check the timing of the engine.

I was looking for the performance curves of these engines but could not find them. Sent a mail to the manufacturers but they replied with a statement saying they don't have any... How is that possible? They state the kw rating of the engine but they don't know at what rpm they achieved it or anything... Stated bore and stroke is also wrong. It's 31mm and 24mm stroke. If you take into consideration the exhaust port ect it does come out at 15cc, so atleast they wern't lying about that.. Anyway, if anybody could help I would appreciate it.

Fuel consumption vs load and power vs rpm and fuel vs rpm

@ ACERC P.s a Nylock nut is only suppose to be used once... The plastic bit should be threaded, you can use them about 3 time before they stop the nut from vibrating loose..
