This guy suffered from the same fate as the red MTD, left out partially disassembled with a crankcase full of brown water, I wasn't thinking and thought I'd use the carb to get another mower running only to find a vaseline like jelly in the manifold, so I left it aside to clean out later. This mower was also part of the six I had just picked up. I took the engine off of another of the six who's deck was broken almost in half in a leap of faith that it ran despite the deck's condition. Success! It sputtered to life with no smoke at all on start up. I don't know the oil's condition other than there was some in it, so I only ran it for a few seconds. Tomorrow I'll need to sharpen the blade, clean the deck, change the oil and spark plug, and test mow. The rear flap spring seems weak, I may have another similar deck I can take springs from, or maybe they just need to be re-seated. The deck is rusty underneath but no holes or cracks, so this one will also be marketed as a beater but as I said before there is a huge market for those.
Photos were taken around 10PM, so they aren't very nice but gives an idea.
The red MTD from before may be sold, somebody called tonight wanting to get it after work tomorrow. They say looks don't matter as long as it runs they'll take it. I think that I have only one mower left that I got today that I haven't looked at, a 6.75HP Tecumseh Craftsman, not self propelled with a rotten deck and jury rigged throttle/governor wire...cable...thing. The primer has a hole so I'll try some barb cleaner to see it it has spark first of all.
On a side not, I've discovered a hazard of working after dark by flashlight. June bugs are VERY attracted to any light, especially a bright LED on my phone. I'll pack it in when the sun goes down from now on.
