Mouse nest in cylinder!

[outbdnut2]

I’ve seen plenty of mouse nests in old motors but just came upon a first. A 1958 35 Johnson with a mouse nest clearly visible in the lower cylinder when I took out the spark plugs! Must have crawled up the exhaust port. That explains why I can’t turn it over all the way with the recoil starter. I’ll pull the head soon – hope mouse urine hasn’t corroded the cylinder wall too bad to bring it back with a hone.

That brings up a good topic… Those pesky little critters will build a nest in anything they can squirt into. I once pick up a nice looking master 16 that had a nest in the muffler. Not to bad till I pulled the muffler and found they used one cylinder for nut storage and the other as a bathroom. I did manage to salvage some parts but the power head was toast. So put a cork in your exhaust snouts.

Sorry to rain on your parade. I’m willing to bet my last dollar, that cylinder is shot. Mice are horrible on anything they nest on.

My only hope that the cylinder isn’t shot is that mice sometimes do not leave their bodily excrement by the nest. After I finish up a couple other motors, I’ll the the head off and see. If it’s shot, I do have another good ’58 35 HP powerhead I can swap onto it.

On the contrary, every time I have removed a mouse nest from any metal object, it’s very rusty, or corroded. Mouse urine is nasty stuff. Yucky….yucky…yucky

Me too. I hate those little stinkers!

If you get the pistons even as far as top/bottom of travel, are the exhaust ports closed?

Funny thing is, that mouse must be Jenny Craig, to be able to fit in through one of those holes 😀 😀
