Hello.
I have a 616 with 16 vanguard (303447-1222) which has leaked (blown) oil due to positive crankcase pressure for several years. It is now only firing on one cylinder, due to lack of spark. Probably an ignition coil. I need to tear into the engine to replace the coil, and probably, the head gasket on the LH side (might cure the crankcase pressure issue). I'd also replace the dipstick seal if possible.
Alternatively, I've looked at replacement. Sounds like this spec engine isn't manufactured anymore (why? design issue?). I've looked into a 18 Hp vanguard repower thru Small Engine Warehouse. However, it is not exactly bolt-in: sounds like I need to reuse the flywheel/blower fan and starter, and muffler from original 16 Hp, as well as possible wiring/throttle cable changes.

On the topic of repair: does it seem like I'm on the right track?
As to the repower: does anyone have a better idea? I don't really like the idea of reusing the flywheel etc, sounds like a lot of work. I am wondering if there is an adapter plate to use the 18 Hp flywheel to couple to the drive shaft, for instance. Or, is there a honda or other engine option?
