I have replaced the 12v dual lead coil, wires, plugs I have tried everything and dont know what else to do. The plugs are wet when i pull them, I have squirted gas in the piston when I took out the plugs. Iam getting sparks at plugs but NOT at points.

Its a 1971 daytona tr100 500cc..Any suggestions. she doesnt have a battery just kick star

The points shouldn't spark. That's part of the reason for having a condensor. You should just have nice big fat blue sparks at the plugs.
Is it popping, kicking, sputtering or anything too indicate it's trying to run?
If you have fuel and spark at the plugs, my guess at first would be your timing. Did you set your points to just start to open at the correct degrees before top dead center on COMPRESSION STROKE?

Did you try reversing the plug wires yet? 180 degrees out is pretty common, like the other poster was saying you gotta be on the compression stroke.

am I missing something about dual output coils?

I thought that bonnies used a wasted spark. ie spark on the exhaust stroke as well.

The plug wires can go to either plug,they both fire at the same time. You do still need to accurately time both sets of points starting with the timing (right) side cylinder and then the primary (left) cylinder. Start with adjusting gap, then timing. If you have the inspection cover over the alternator rotor, and it has a pointer in the case, and lines etched into the rotor, you can kinda cheat and get it really close.
Get the engine on compression stroke for the timing side cyl. and turn the engine by hand to where the next line to cross the pointer on the alt. rotor is almost ready to do so. Using a screwdriver, turn and hold the points cam at full advance. While it's at advance continue to turn the engine by hand until the line on the rotor is perfectly lined up. You can release the cam back to normal for a minute...
Now you'll need a thin feeler gauge of .0015" or a piece of cellophane. Hold the points open for the timing side cylinder (the left set of points) and let it grab the feeler gauge or cellophane.
Loosen the whole points plate just enough to be able to turn it by hand. Rotate the points cam back to full advance and hold it there. Now turn the whole points plate until the lobe on the left set of points starts to go up the "ramp" on the cam. At the exact position that the points begin to let go of the feeler gauge or cellophane, lock the points plate down ad your timing side cylinder is timed!
Do the same thing for the other cylinder, ensuring you're on compression stroke for that side now. Only difference is you'll have to adjust the plate with the concentric screw that the right set of points is on, instead of the whole points plate.
You probably already knew this so sorry if I got too detailed! Much easier than it sounds in text though!
Hope this helps!
