Cleaning in hard to reach places

So I am trying to clean an aircooled engine and I am not sure how to get in between the fins. Any suggestions? A toothbrush is to wide.

gun bore brush and rod or engine cleaning brushes

Bottle brush?

Glass bead blasting cabinet?

DIY Soda Blaster.

End thread?

Don't really have time or room for that. The gun bore brush idea should work well.

Scotchbrite pad folded in 2 over a paint stirrer stick + a squirt of Berkbile 2+2 or lacquer thinner.

I just did some very filthy Yamaha RD400 cylinders and it worked very well.

That said, if they're loose parts a blast cab is perfect. Unless you're going to hone 'em while they're off be very mindful to plug the bores though...

I think they are going to need to be honed since the engine was sitting in pieces in a shed for who knows how long before I got it.

Pressure washer, purple power, and the red "kill" tip.
