I have 2 Howard 350s, one in use and one for spares, and a 200 that needs the engine replaced. The 200 looks easy enough, just a straight swap with a Honda or equivalent Chinese copy. The 350s however, don't look as easy (I have little experience of this). Looking to  replace with a 5.5 or 6.5 Loncin (now badged Villiers) engine. Does anyone have any experience of swapping to these?
