C-9 w/o spark

[Jarhead ☠]

Hello group, I have a question about an ignition problem I'm having.
So I've cleaned and tested the entire system and still have no spark. I've replaced the condenser and sparkplug and still nothing but if I use my in-line tester and attach the plug end on the bar stud it will spark like crazy. Am I having a grounding issue?

I think it's possible.How is your plug wire?It's not much trouble to do this - take the coil off & make sure there's no dirt or grease anywhere it bolts down.If you have another coil from a parts saw put that on & see what happens.

     Back a little over 2 yrs.ago Leon ran into a similar situation with a customer's 7-19 (?).He'd have the spark jumping 1/4 in.& figured the condenser was good (original).He ended up changing the condenser & problem was solved.The condenser would give spark,but not under a load while on the saw.Just because the condenser is new doesn't necessarily mean it's good.That "new" condenser is 50-60 yrs.old.Condensers will go bad just sitting on a shelf.The only person I know who you can get a condenser from that's tested before you buy it is Bob Johnson.The last time I bought a C series condenser from him he told me he had to throw away 2 NOS condensers before he got a good one.

Do you have another saw to test the new plug in? I have got new plugs DOA before.

So today I replaced the entire coil, points and condenser assembly and still no spark😡
If I attach the tester and spin the flywheel I get nothing but if I attach the boot end to the bar stud it has a ton of spark.
I said let me try something, hold my beer!
I attached the sparkplug to the boot and spun it and and nothing but then I let loose and went all-out with the drill and it slowly started to ever so softly glow and then it finally went crazy. I'm thinking the condenser needed to be charged because it will give a huge spark touching the cylinder now.

Al,I think you have what's known as a leaky condenser.It's in between being good & bad & won't last long.A leaky condenser will cause your points to wear out prematurely by pitting them.The leaky condenser will transfer the metal from one side of the points to the other side,this is known as pitting.

Well she's all cleaned up and a runner!
I'm going to take the carb off and pressure test it because it doesn't want to pull fuel easily.
