What’s the best way to get the stock paint off engine cases and cylinders?

If it's stock paint, I have always just scuffed it cleaned it and painted over.

try aircraft paint stripper. Or sandblast.

Get a Bead Blasting cabinet. Tractor Supply had them on sale a few weeks back for $67.00, You just need a good compressor to run it.

The EPA has banned the use of methylene chloride in the US. Aircraft cleaner you get in the store no longer has the active ingredient that once made it so amazing. You might be able to find old stock on eBay. There are a few groups that still manufacture the compound you can 'add' back into the store grade junk. These guys are right down the road from me https://store.carolinachemical.com/buy-dichloromethane-reagent-acs

Thanks for the info. I'm probably going to scuff it up and see how it looks. there's a little corrosion under some of the paint from salt water though so we'll see.

The new stuff really sucks.

Wire wheel in a drill. I would only be aggressive on places that need to be smoothed out,

I have been cautioned about sand/bead blasting internal engine parts because the beads don't always was out completely. For sensitive parts with tight tolerances or intricate shapes it was recommended to me to use soda blasting or walnut shells.

2 strokes have less internal passages for the beads to get hung up and then wash out later than in 4 strokes so it may not be an issue.

Sandblasting or bead blasting hands down. Way easier than chemicals, sanding, scuffing or wire wheels. Whenever I am going to blast parts with sensitive areas like say a cylinder or cases, I just heavily tape off anywhere that I don't want to get blasted or media to get into. Then just vacuum and blow the part off before removing the tape and then clean everything really really well. Also for any sensitive areas that but up to somewhere I will be blasting i always use several layers of tape and then just keep an eye out to make sure you don't burn through the tape and you will be fine.

glass beads if you're careful with not blasting sealing and bearing,machined surfaces and if you know you're going to be sloppy,use walnut shell.

Red scotch brite the crap out of it then spray it with epoxy paint using proper protocols

+1 on sand blasting, I used a bucket blaster on a compressor and blasted my assembled motor with duct tape over ports. Strips it right down to the bare metal with a good air compressor. Just wiped it down and painted.
