Dave I tried the full choke by adding a a piece of steel to the throttle to ensure the choke was fully closed but it made no difference so I removed it.
Gambler I don't know what the brand is , Rato or something I think, it isn't here at the moment. It is a 6hp and cost $160 and the shaft size is 1 inch. Stick with your Honda. There are some 196cc motors on ebay but you need to be careful, the shaft is shorter and they are only 22mm ones, easy to get caught out
