Thanks David, I LOVE this sparky type of chat, hope we dont bore the others::: HEY IM ENJOYING THIS FUN DISCUSSION AND NOT BEING ARGUMENTATIVE MIND YOU, we alllll have the right to our opinions, I respect yours and you mine Im sure

I DEFINITLEY AGREE WITH YOUR STATEMENT "You can get more effiency and power out of the engine if it is timed correctly"

Of course (as typical lol) theres MORE that must be considered, such as below, and also we have to consider BOTH the static/start timing as well as the advance run timing:

1) If it were a HAND CRANK Magneto Ignition, then its static/start/impulse timing has NOTHING to do with if the rest of the tractor is 6 or 12 volts: Their mags static/start/impulse has to be right at TDC if they are hand crankers otherwise they can kick back if too fast OUCHHHHHHHHH but harder to start if their static/start timing is too slow.

2) If its a battery powered coil and distributor ignition but still a HAND CRANK, again its static/start timing still has to be pretty well at TDC so she dont kick back AND AGAIN THATS TRUE REGARDLESS IF 6 OR 12 VOLTS

NOWWWWWWWW to your point:

"The older timing was set so that you could hand crank or start on 6V. The 12V starting allows you to advance the timing because a little kick back does not hurt"

My thoughts are:

a) If it were a Mag, theres NO difference if the rest is 6 or 12 volts (mag has nothing to do with any other electrical stuff)
b) If its a battery powered coil ignition and a hand cranker, again NO difference (see above)
c) If its a battery powered coil ignition ELECTRIC START:::: Its indeed true if the static/start timings a bit more advanced theres no crank to kick back and harm you BUT THATS STILL TRUE REGARDLESS IF 6 OR 12 VOLT AND EVEN IF AN ELEC START, TOO EARLY STARTING TIMING FIRING CAN BE TOUGH ON STARTER DRIVES

I guess what Im saying is in my humble opinion that static/start timing shouldnt NOT CHANGE REGARDLESS IF 6 OR 12 VOLT.

NOTE 1. I agree proper timing makes her run more efficient, Im NOT saying anything contrary to that

NOTE 2. I would argue static/start timing needs to be near TDC so a hand crank dont kick back and hurt you or a starter drive (on elec starters) dont risk get damaged BUT I SEE THAT THE SAME REGARDLESS OF VOLTAGE

I just fail to understand how or why you should advance the timing if you convert from 6 to 12 volts. Timing has to do with RPM,,,,,,Compression,,,,,,,,Fuel Octane and again IN MY OPINION has nothing to do with whether the starter motor or lights or coil voltage IS 6 OR 12 VOLTS and if it were a magneto ignition then it reallyyyyyyyyyy dont matter. Similar, the static/start timing cant be too much before TDC
REGARDLESS IF 6 OR 12 VOLTS AND REGARDLESS IF HAND CRANKER (hurt your arm) OR ELECTRIC START (risk damage to starter)

Thanks again, great discussion and until proven otherwise THATS MY STORY N IMA STICKIN TO IT LOL

God Bless yall
