best 6V battery value

[buckchills]

Got a new toy - appears to be a 42" HG.  Was told it has a rebuild carb and magneto, but hasn't been turned over for at least  years.  I'd like to see if it actually works.  Planning on pulling the plugs and oiling the cylinders, and seeing if it actually turns over.
Provided that it does, I'll then water and oil it thoroughly, gas it and fire it.  Does anyone have a recommendation regarding battery size and/or mfgr for these, once I get it spinning properly?
