Hello Butch and Welcome to the forum family . I suppose either engine will work . I have a preferance to Briggs myself . If going that route I would look for an engine with at least a ball bearing on the PTO side of the crankshaft but thats just my opinion. Lots of folks are using the Honda or Honda clone chinese engine . You can find more info on this subject here on the forum .
Enjoy your project and visit the forum often .
