I wanted to add that to measure a capacitor/condenser you need a pretty special measuring device. If I were you I'd just order the right condenser and be good for another 20 years.

The genuine condenser is $20 at onanparts.com

On amazon you can get both new points and condenser for $22, but obviously they're aftermarket.

I think what I'm going to do for the time being is double check the compression with a gauge and then reinstall the original condenser. I did notice when I removed it that its connection to the point was a little loose. If that gets my spark back then I'll replace the plugs and see what that gets. Beyond that I'm afraid I'll be at a loss. I'm going to call a local small engine shop today and look into their rates.

I do love to work on equipment, but I also learned long ago that a smart man admits when he doesn't have the answers.

The condenser body needs to be well grounded to the engine, so make sure that's so by filing some of the paint if there's any, where you attach the condenser.

You'll get this figured out, I'm sure, but I think you need to eliminate possible problems using some new parts and doing a proper compression test. Otherwise we'll be running in circles doubting everything all the time.

I think it is time start with the basics . If you can answer these questions it will be easier for us to steer you in the right direction . Other wise we are just guessing at what is going on .

How did you set the points and what values did you use ?
What is battery voltage and what is it at the B+ on the coil with and without the points side ( - ) hooked up ?
What is the B + coil voltage when flywheel is about 10 degrees before TDC . The flywheel and timing cover are marked and you can see through the large hole in the front tin cover .
If you can do this before doing anything else it would help .

It's a learning process Vivala. The more you work on these GT's the more you'll learn, and the next troubleshooting ordeal will be easier. Before you know it you'll be answering other members posts about their problems. I can guarantee it Vivala!

Keep the Peace

Assuming that the 312-0246 at onanparts.com is Canadian dollars?
