How much spark should there be??

[masonryman13]

I have gone just about crazy playing w/ jetting on my 84 r aircooled. I have jetted to scary low #'s and it will still foul the f'in plug. I've gone through 29 NGK br7 & br8es's. I put in another new plug today and decided to check the spark b-4 installing it. As i turned the motor over i could barely, I mean BARELY, see the spark. How much should I see??. I know its hard to say what I should see, but what's a good idea or do u have any pics?? Maybe this is my whole problem??:wondering

Try it at night, the plug needs to be grounded. It should be a pretty good blue spark, the harder you kick the faster the spark. You could alway grab the plug and crank it, you'll know if its a hard spark or not. lol

Have you tried running without the air filter? Check the reeds?
