I'm figuring out what to do with this thing. Help me out.

I have a 82 year Pony tiller and I really like it due to it being non-compliant(no deadman handles).

It has an electric start briggs and stratton motor which is getting a little tired. I will say it is in prime condition for a rebuild so that is an option. I know how to do everything to it to get it up to spec but I am looking at the least 125$ plus a battery.

I found on the internet an option to install a new intek 5.5 horse for around 279$ but I need to monkey with the belts and prop the engine up on spacers due to the design change.

What do you all think?

Rebuild the old 5 horse and be a purist?

Put a new 5.5 intek on it thinking it will really crank up some dirt with an overhead valve motor?
