Hey guys. Just got new spark plugs and wanted to get the correct gap. I think it's .045 but just wanted to check and make sure. Thanks for the help!

Thanks!

One thing I found said ".035 with points..045 with electronic ignition."

It should be on a stick on the motor though shouldn't it??

It's usually on the plastic cover on the carb....​

It was on the motor. .035. You were right, I was wrong.
