Attached a video of my spark on my no go motor. Can you take a look and let me know if you think this Spark is too weak?

Re: 60 lightwin is this enough spark?

HI jamn. Meh......hard to tell really. I know it's hard to pull, film and hold the wire, but grounding the plugs against the block is hit or miss at best, even though we've all done it. I would suggest a little $5 gap tester from the auto store. The work quite well and you can adjust the gap to test the strength of your spark. Yours should jump a 1/4" with a bright blue "snap". Here's a great magneto rebuild link and a vid of a guy with a motor similar to yours getting good spark. (of course he's using the grounding on the block trick, but you get the idea). You can get any ignition components you may need right here at iboats. A tune up kit is about $20 as are coils.

Thanks, I bought the tester and spark is more than good. So I will start a new carb thread to figure out my fuel delivery issue.

Glad you've got spark. Assuming you have good compression, all that remains is fuel delivery. Here's a handy link for carb rebuilds. It's for a slightly different model, but all of the steps are the same. Carb kits are also about $20 here at iboats.
