I have a nos hs45 short block. I also have a tired hs50 engine will the head, and flywheel from the hs50 work on the hs45? Both engines are post 80 builds.
The short block was labeled 4.5hp my mistake. The tag says Sbh-453A/7299F. This would have been for a roto-tiller or snowblower with a reverse because it has the extended camshaft.
I got the engine put together last week. I had to change the cam and side cover because the short block had the extended cam for reverse. It took two downer engines but now I have a new 5hp. Now to find a bike to put it on.
