Hi BB and Bon_Scott

Thanks for the input I would have not even thought about shaft size, yes you are right they have a 19mm/3/4” or larger engines a 1” shaft!
If I go down the route of a new engine think I’ll stick to a Briggs! Not a great deal more $$

Yes I knew it’s chevy orange don’t know why I wrote red think I was watching a car resto show and had it in my head!!
