Ive done it many times (converted a 6 volt tractor over to 12 but used the old 6 volt starter IF THATS WHAT YOURE DOING???) and never had a problem HOWEVER that being said it can be tough on starter drives due to the high kick in torque. It still turns the same direction regardless of polarity, original was POS ground.....Of course you can get a 12 volt starter if you insist........ Things Ive done (when using a 6 volt starter on a 12 volt system) that can help soften the blow but are NOT absolutely necessary, many do nothing but that's just me..
When I choose a 12 volt battery I don't buy a very heavy duty unit, maybe a lighter duty like say a 500 Cold Cranking Amps NOT a 750 or 1000........
When choosing battery starter and ground cables I might use say a NO 4 NOT 2 or 1 or 0 like on a 6 volt tractor
Of course if its a battery powered coil ignition you either add an inline series voltage dropping (12 to 6) ballast resistor orrrrrrrrrrr buy a new full 12 volt rated coil. Match coil polarity to tractors ground. If a mag no change required
You may consider converting overt to NEG Ground especially if you're going to use a new alternator as most are Neg. If a generator they can charge at either polarity if polarized correctly. If a genny they can be converted to 12 volts and you also need a 12 volt Voltage Regulator if its a VR system instead of a cutout relay and manual Low High light switch charge control......
If left at 6 volts a B can start fine if you have a good heavy duty battery and use like 0 or better yet 00 gauge cables but thats not your question, just saying.

Today's Featured Article - Earthmaster Project Progress Just a little update on my Earthmaster......it's back from the dead! I pulled the head, and soaked the stuck valves with mystery oil overnight, re-installed the head, and bingo, the compression returned. But alas, my carb foiled me again, it would fire a second then flood out. After numerous dead ends for a replacement carb, I went to work fixing mine.I soldered new floats on the float arm, they came from an old motorcycle carb, replaced the packing on the throttle shaft with o-rings, cut new ga
