Spark plug Gap?

I recently picked up two little 2003 model 90cc 2 stroke Sportsman’s, for the kids. They need some serious maintenance. For starters all breaks seam way weak, will slow you down but not lock up. There appears to only be a adjuster for the parking brake. I guess maybe all new pads will help. And one is load as can be, I don’t see exhaust leak, but previous owner said all it needed was the header gasket about $4.00? But it appears the muffler was welded on solid to frame. So good luck there, maybe cut it off?

I have the owners manual, but no service manual. My real question is spark plug gap, manual says “
Proper electrode gap is .24”-.28” (0.6-0.7 mm).”

All I have is standard gap, and I’m thinking manual has a typo and should read .024”-.028” Cause a ¼” seams like a rather large gap lol? So does anyone know proper gap. I could try and convert the mm but thought it may be wrong as well. Thanks for any help.

.028 is right! Not Inches!

Thanks a lot. That's what i was thinking, I cant believe Polaris Dose not prof read there manual's! .028" is a small gap, but I knew that .24 to .28 couldn't be right!
