Thanks to all who responded about my carb problem. I'm looking into it. Now my question is regarding the conversion from 6V + ground to a conventional 12V system. Assuming I could do all the work what would that kind of conversion run me ($) in terms of parts? What parts would I need and would they be available from your average (rural)auto parts store?

Thanks again for your help - Matt

For me, there is no need to convert. My 6 volt G starts on the first crank. Once started, I mow for at least an hour, so there is recharge time.

Even if it didn't charge adequately, a battery charger is not much of a hassle.

But, I'm a bit of a purest about keeping old things original

Listen, what I did on my G was get my starter and the generator rebuilt to 12 volts. Get a 12 volt coil, too. About $250, works good, and keeps the original look. I did try the alternator, but it looked so bad being so big on that small on an engine. Let me know what you decide to do.

The cheaper version is to use the delco alternator with internal voltage regulator, that has external signal charge wire. This is called the "three wire" alternator instead of the single wire alternator. This was the standard alternator used on all GM cars and trucks form 1975-1985. You can get one at Auto Zone, new for $35. Will need a resistor and a coule extra little wires to make it charge, very simple. I agree the starter solenoid modification is a good one. I used a big push button instead of a key start.

I've done it with 3 Gs. Get a single wire alternator. It has the regulator built in and eliminates a lot of wiring problems.You will have to fabricate a new mounting bracket. While you are at it put a bolt terminal on the starter in place of the mechanical starter terminal. Then you can use a Ford 3 terminal type starter relay and a remote key type starter switch UP FRONT.
The alternator will run you about $70. You can use a garden tractor type battery. Good luck,Ed

TRY A 8V BATTERY & 8V REGULATOR ON YOUR GENERATOR , I DID , WORKS FINE ! ALL IS NEEDED IS MORE CRANKING POWER !
