I bet a fella could make a killer starter out of one of these, but which one to choose??

I have heard of using a chainsaw with a no bar. Put the starter gizmo on the clutch. That dispenses with the pesky car battery.

Sullivan sells a car type starter with a big price $500 special order

One of our long time members has been using a Stihl chainsaw with a large cone mounted where the clutch goes for many years. No battery, starts every time and runs the same fuel as his aeroplane engines. Case was messed up and couldn't be fixed economically so it was turned into a starter.

I have probably $125 in a starter like this. I bought the Dynatron with the Miller reducer and 3" cone at a swap fest in Columbus Ohio in what looked like unused condition for $90. The two batteries were $10 and then there was the switch and muffler clamps from the auto parts.

How about this one,

My dad and I made it out of a motorcycle starter that was a freebie (Honda 550cc). It requires a descent battery but I have started a 64 cc engine with it un-assisted, it will start a DA 50 all day.

It had a little trouble with a Quadra 75, it just needed a little help to get over the first compression stroke and then it spun the heck out of it and started it. I have ran it momentarily on 24 volts but haven't tried to start anything that way. I'm looking for some bigger wires for it also, these will get a little warm if you really load it up.

I may re-make it someday with gear reduction, then it would probably start a 100cc engine.

The best kind are the freebies that inspire an idea

I like both of the starters shown. I've been wanting one of those Miller reduction units for a long time. I actually called one day to order one, thinking it would be maybe 50 bucks at the most, but when they started talking over a hundred bucks I said no thanks! Still want one though... Do they work well?

I us a Sullivan Dynatron starter with a 6S 5000Ma Lipo strapped to the bottom. No other reduction. Its starts all my 30 and 50cc motors and occasionally a fellow members G62. Its my one starter. I used it for my heli's and planes. Very small packaged for the job it does. The LiPo stays charged for quite a long time too.

The Miller comes as 4:1 reduction. You almost have to run 24V to get the cone moving at a decent speed.

Hobbsy has Miller that he put a larger pulley on the motor end and it is 2:1 which makes for a better speed. It will work at 12V or 24V. He has it on a Big Hobbico

I like the Sullivan Dynatrons. I have three of them. I tried one of my Dynatrons on a Saito 220 the other day and it started the engine right up on 12V.

I also have a Sullivan Hi Tork which turns 5500 rpm on 12V which is too fast.

The Dynatrons turn 4800 on 12V

The newer Tower starters are made better than the old ones. The new ones have steel end bells just like a Sullivan with a plastic cover. The old ones had plastic end bells

I use a milwakee 18v battery drill with a 2.25" starter cup and insert from tower. Put that on a grade 8 allen bolt and it starts my G62s with no problem. The club has a riding mower starter adapted for starting. It works, but not too many use because of the car sized battery to be hauled around.

I use an 18 volt Makita with the end of an old starter shaft cut off and chucked up like a drill bit. Just make sure to get the chuck good and tight.
Try it you will like it.
