I put in new points heavy duty coil rotor rotor cap condenser I got excellent spark when I go to start it the 6 V battery turns it over very slow even though its new and fully charged but when it starts it runs excellent so I let it run for half an hour thinking of something what time is loosen up but even after that it starts hard. My question is can I put a 12 V battery in there what will I do or is there something else I should try first? This is the old buzzard again Jack

If the starter hasn't been reconditioned and freshened up, that is always a good thing to do. Battery cables on 6 Volt must be of a larger diameter to get the just done. Connecting the ground cable directly to the starter mounting set screw sometimes helps improve electrical current flow. Is the starter set screw clean and tight ?????

Do you have 0 or 00 battery cables or are they auto type 2 or 4 gauge cables?? If auto type that is likely to be your problem

Be sure the starter and cables are right as others posted. Make sure there is no paint under any connections -- bare metal at contact areas.

Have you set the timing with a light per the manual?

If you put a 12-volt battery in you need to upgrade the charging system to 12 volts. If you change to an alternator, it is easiest to convert to 12-volt negative ground and use the common negative ground alternators, in my opinion, others may differ. You have lights, those will need to change to 12 volts. You will need to add a resistor ahead of the coil. Ideally you will have the starter rebuilt to be 12 volts, it will work as is, how long and how violently it engages as an unknown. I have run several for years as 6-volt after converting the rest of the system to 12 volts, without issue. Others have reported broken starter noses or had other troubles leaving them 6-volt in a 12-volt system.

By starting hard you mean it turns over slowly? Just went through something like that with my WD-45. First ditto on the size of the cables. I would bench test the starter. I took mine apart and cleaned everything. Installed new brushes. Still had trouble. My ground was not making a good connection. Cleaned up all the connections and now it starts and runs better than before. Even if the ground looks good clean it up. Not much room for bad connections on a 6v. Good luck and tell us what you found.

I cannot stress enough having the starter freshened up, unless you KNOW for certain it is fine. I just pulled the starter off of my One-Seventy gas because it seemed to be slow to crank (always start) and I found a broken spring on one pair of brushes !!! So, it was cranking, yes. But it was cranking with 50% power !!!!
