Mine weighs 4 lbs - 15 oz

It has the CH ignition but this weight is not with the ignition unit.

The CH ignition uses the Zenoah coil and mine has a Bosch shielded plug cap and shielded pilug wire all the way back to the coil per the Toni Clark suggestion.

Mine has the Zenoah flat steel mounting plate

An aluminum Spehar muffler

and the current Zenoah straight pull carb mount

no prop
