I saw a sale on the Internet address of the engine Rotax503
But this engine is not common that I shall:ponder:

It is not our only two spark plugs and spark plug of the four common:para:

And it is not CDI
But the platinum ignition
It has two carburetors

All of the machine pictures in Attach Files:)

Seller explained that the older models of this machine, but the power was much greater than the new
It is said that the machine was bought new but for many years after the stock:ban:

I would like to ask you
The machine's actual year of production, the performance of the machine
The most important is that it is not suitable for aircraft engines
Thank you very much:gig:
