Can you take the screen off, what i would call the front of the engine, and bolt a pully on the front also.

HondaSpecialist· 12 years ago
The screen covering the cooling fan can be removed for service/access/repairs. A pulley or drive device should only be mounted to the PTO side. The other tip of the crankshaft has just enough thread/spacing to fit the large flywheel nut; nothing else should be mounted to this side of the crankshaft. I've heard of some aftermarket/third-part recoil start devices being offered in Europe, but have no other details. -Robert@Honda

This engine would come with an oil filter, fuel filter, air filter, and spark plugs. It would not come with engine oil as that would have to be purchased separately.
