I'm glad i found your post as i am looking to buy a honda S65 that is missing a carb and manifold (cheaper just to replace it with a new engine from lifan IMHO)

How did you wire it up since the S65 is a 6 V system whereas the lifans are 12 V?

Was it difficult to swap out the engines? (i imagine it isn't).

Any advice you could give me would be muchly appreciated.

Cheers
A
