After rebuilding my Lawn tractor last year, a neighbor asked me to help his son rebuild his lawn mower.
Dad's mechanical abilities are pushed changing a light bulb (really), but the kid is pretty handy. I've helped him a number of times, and he's helped me with a number of projects.

So the son decided he wanted to do what Uncle Kevin did, similiar mower setup.
Slightly newer B&S he picked up at a yard sale. Engine is bad, he ordered a +.020 ring set. He decided std wouldn't work and .010 isn't available.

Well we can't hone it to .020, but the cylinder isn't bad, so I figure we hone it nice and grind/file the ends of the rings.

What kind of ring gap should I shoot for, the manual he got says if over .030 replace. But doesn't show what to go for when installing, (Thanks B&S).
Other than direct replacement (cars) I've always had a recommended ring gap in the manuals.

We are doing this tomorrow, Saturday, so my guess is .005 to .010.

Any help is appreciated, Dad's buying me beer if we get it running.
He'll probably buy pizza for lunch, and a few beers anyhow.

Thanks

One of those Dads OK to a jerk, Kids got potential. I figure(Hope) I can help guide him a bit.
