HI:
I was buying some rings for a a 40cc piston at a local store when I saw they sell the SUMEC 25cc 2 strokes engine complete with flywheel fan,, clutch and starting rope. ( They sell it as is, no discount if I return the accesories!!
The engine is quite similar to talon 22 cc, with the barrel type carburetor, side mounted carb and exhaust in the opposite, it has great compression, but the coil is mounted to a metal piece that is not part of the engine, so in order to reduce weight it should be used with ignition.

The cylinder uses 4 bolts to the crank, it has very good cooling fins even on the top of the head and around the sparkplug.

Anybody know something about the performanece of this engine??

Thanks.
