First, it is running. I replaced everything from the ignition switch to the spark plug but not the ignition switch. It's a front mount 9N 12 volts everything except the starter. At first it would not run, nothing nada so I took the coil off and checked the timing again and the firing order and put it back together. Zip nothing. Pulled all four plugs and watched them firing for a while, quite fascinating. So I took the carb off for something else to do. Lots of petrol flowing through the pipe and out the bottom plug, checked the main jet and it was clear so I put it back together. Something about the spark bothered me it wasn't the mighty flash I had it mind. I took the coil off for something to do and compared the length of the pig tail. It was 1/4 inch shorter than the old coil, so I made it longer. Zoom zoom but now it is running crappy at high revs, used to run fine. It does not sound like it is starving and yanking the choke floods it like it should. It's real sweet at low revs up to about a thousand maybe 1500 but after that it runs like a bag full of broken ( expletive deleted ) I have read the posts on the ignition switch and air leaks. Please tell me again how you check for air leaks. Do you think it still might be related to the weak spark problem from the short pig tail, I could yank it some more. Darkness forced me to retreat. But it is running. Thank you BC Mike C

ok good so far. just for grins, in case you haven't done so screw yourt needle valves in all the way then back them out 1.25 turns.

Next, adjust your low idle needle first. that would be the smaller needle valve. at low idle turn that small needle on the carb in and out until it evens out as best as the engine could.

Next, adjust your high idle screw and throttle it to high idle and turn tyhe main needle in and out until it evens out and high idles as best as you can get it.

You may have a small piece of debris in your needle or jets but i don't know if you rebuilt the carb or thoroughly cleaned it out with a strong solvent, compressed air, and new jets ot any type of rebuild kit.

Is your condensor new along with clean points and correct gap? and are the plugs gapped right?

New plugs, plug wyres and end caps, rotor, cap, condensor, coil, resistor ( correct ohmage for a 12 volt coil ) Points at 15 thou, plugs at 25 or whatever the book says, timing checked made sure I was turning it the right way. Carb kit about four years ago. It ran fine one week ago before I fixed it, was a little hard to start so I thought I would put in the new pieces before it got too cold and the snow was around my ears. The only odd thing about the carb is that it likes the small jet set a 1/4 to 1/2 turn out, any more and it runs rough at low revs. It is running sweet at low revs. Had a problem with a piece of crud in the main jet once before, I checked that and it seems okay, can check again. My list of possibilities are, the ignition switch, an air leak, float level, weak spark as that was the problem with getting it fired up, advance, and crud in the mainjet plus any suggestions the group might have. Thanks BC Mike C

Do you have resistors in series?

do you have the correct readings at the coil? two resistors to the coil?

sounds like a condensor issue.
