Success! I had to use channel locks to grip and pull the connectors apart. Once apart, the spark came back. I'll wait to find the source of problem. Now that I know that it's outside the motor, and with the schematic, it shouldn't be too difficult to find and fix the problem. FYI: On one circuit, th...

Thanks Todd, I did disconnect the plug at the key switch, but the "no spark" condition still exists. I have done some visual checks of the wiring harness and wiggled things around a bit, and still no spark. I thought that disconnecting the other harness connector would be another quick che...

Hello All - I think that I have a wiring/harness connection problem but I'm having trouble isolating the problem - I'm trying to disconnect the "molex-type" connectors but am having trouble figuring out how to release the latch that holds these together. Does anyone know the secret? FYI - ...

Thanks Harley - I'll check it out.

Thanks again for the help Harley .... and now a similar question ... how to I identify the correct seal to buy?

Hello All, My 77 Liquifier has a good spark but always needs starter fluid to start after sitting for about a week. Choking it just doesn't seem to be enough. It idles and runs well enough, it just starts hard when it's cold. If I start it every day, it starts on the first pull. I've had some advice...

Up date: After replacing the CDI, I got a good spark and within a few minutes (enough time to "rig" a feed line from a container of fresh gas) we had a smooth running motor. I was really surprised that I had two seperate problems - a bad stator and a bad CDI. Not sure how that would happen...

Thanks for the help JD600 tand JDT. You were right about the loose track. At first I didn't think that the track was too loose. But my manual said that the chain tension was not adjustable, and the sprocket and chain looked fine. So, all that was needed was a little tighter track to solve the proble...

Update: Cleaned connections, mounted CDI - still no spark. Because of other obligations and travel that keeps me away from home these days, I'll try the replacement CDI next weekend.

I think that I have a loose drive chan issue. The symptom is a loud popping sound and shaking when the sled in under a heavy load usually while trying to get moving. My goal is to guide my son through the process of checking the chain tension and adjusting chain tension.... if my guess is right abou...

This is the stock CDI with the two round (2 and 3 conductor) connectors. Yes, there is a fairly short wire with a terminal on the end that I am sure is the ground wire that is secured to the cdi with the mounting screw. My son tells me that the wire the has been "pulled loose" is actually ...

I'm pretty confident that I can figure out where the brown wire pulled loose from but I'd just like to speed up the troubleshooting process by eliminating some of the guessing. I'll make sure to ground the box .... when I get home.

Here's an update: You're right about the right tool. And now, with the new/gently used stator and trigger/donut in place, the symptom remains - no spark on either plug. That was Sunday. Today, I am on the road, away from my project until the weekend with snow in the forcast .... so I'm trying to sho...

Thanks All - I'll give it a try over this weekend and let you know how it goes.

I think that I can answer my own question. My "cover" is the flywheel which you are saying will not fit through the opening shown in my picture.
