I just got a1973 Panther 440 Kaw, Walbro carb, non cdi ignition and non electric start. The problem is that it only has spark on the recoil starter side, not the clutch side. Where exactly should I start the testing. Thanks

Non CDI means it has points, my guess is they need cleaned. Pull recoil off and flywheel and all that fun stuff and they should be back there. Check that everything is working correctly, opening and closing. use emory cloth or sandpaper to clean the contacts in the points, I like to use an emory board (AKA Nail File) its easier to get in there than folded over sandpaper or emory cloth. Once cleaned re gap to spec, it should say on the engine ID tag what it should be.

Try that to start with and if that doesn't work I would check on your plug wires etc..

I'll check the points. Are the plug wires replaceable? i removed the carb and plastic cover over the coils to check the plug wires and it seems to me that they don't just press on, are the plug wires hard wired into the coils?

I'm not sure on that, I haven't ever had a problem with wires but its something to look into if the points dont fix it.

first thing I do is check the spark plug cap and make sure they have a good conection to the wire itself. You cannot change plug wires as they are glued or epoxed into the coils. next, using jumper wires with alligator clips, try reversing the white and red at the coils themselves. see if problem jump to other side, if not, I'd say bad conderser first, as I rarley see points go bad. You do have the engine wiring harness disconnected, right?

I will give up my vintage sled when they pry my frozen dead thumb from the throttle......WOT of course!

I'll check the caps, when you jump the red and white wires are talking about the ones that come out the engine and have bullet connectors on them? The coils have two wires connected to each they both appear to be red and black wires?

Yes, I am talking about the 2 wires coming out of the engine, with the bullet connectors. Clean them up, you may find the white wire is so dirty it appears black. Does everything appear to be stock, all the connectors under clear plastic protectors? You should have white with a black to one coil and red with a black to the other coil. OR...you may have reds and one with a tracer??? The black are the kill side of these coils. red and white should come off the points. SHOULD....LOL
hey...take pics....

I've had all sorts of issues with plug caps and ended up cutting back approximately 1/2" of the existing wire and replacing them (The ends unscrew from the wire) These motors are also know for crappy coils and you'll know that they're on the way out when you're motoring along nicely down the trail and the motor will start losing power and sounding like crap and won't idle. Sixty-Eight is correct on the bit about the condensers, Just remember that Kawasaki doubled up on everything on these motors, two sets of points, 2 sets of condensers, Ugh ! Also if you're going to clean your points with anything abrasive, finish it up with a Dollar bill across the surfaces. Don't ask why but multiple Old-Timers swaer by this and it does work !

Emery cloth leaves pieces of itself in the points and is not a good conductor. The dollar bill may clean this out.
A points file or welding tip file works good for this operation.

More than likely dirty points that have a thin coating of oxidation on the faces from sitting. We purchased a 73 John Deere that had sat for YEARS (only 300 OE miles on it) Replaced plug caps, spark plug wires, everything good first, then went after the points, all oxidized to the end, so from gentle nail filing and a few dollar bills swipes later with a quick blast of CRC electrical cleaner, had bright blue spark and the machine runs like a beast! more than likely in your situation the points are corroded slighly.

Time for a good cleanin!
