Hi All, I have an HU700F with a Honda GCV160 engine. The blade bolt sheared and despite many attempts, I could not get the piece out of the shaft. I purchased a used GCV160 with the appropriate shaft diameter and length, and swapped the engine, however I am having trouble getting it to run. It seems this engine, from a Honda mower, has more controls than the one used on the Husqvarna - it has a throttle cable connection in the same place as the Husqvarna model, but while that is the only control on the Husqvarna, the throttle on this engine has 2 speeds plus a "choke " position; also there is a "Flywheel brake lever" which seemingly shuts the engine when released. Is there any way to adapt these to the control cables of the HU700F? Or am I screwed? The Honda mower it comes from is an HRT216. Does the Husqvarna even have a flywheel brake control? Or is that the only control and the throttle is actually fixed? I know the old engine had an automatic, rather than manual choke, and I was thinking of swapping the whole carburetor/choke mechanism to get around that. Obviously, I could probably swap out the crankshaft, but that is beyond my expertise. Any thoughts would be appreciated.

The basic engine block, crankshaft and head are the same. The 2 different mower manufacturers had them configured differently. Just swap over your original engine external parts to get everything operational as before.
 
So move the carb, auto choke mechanism and seemingly fixed throttle over? I'll give that a try. Thanks.
