Well, with the cold weather finally hitting, I took some time to mess around with another odd project I have.
I've brought it up here a few times, in these threads. They're good sources to catch up on the roots of this project:

Update on two other projects (http://www.mercurymarauder.net/forums/showthread.php?t=30462)
Anyway...here's the story in two phases...
The Beast Roars To Life - ...Again...
Contrary to popular belief, this has nothing to do with chili…
On Sunday though, the beast did roar to life. By beast I mean I had this thing running on all 1 cylinders!
Yep, I got the hot-rod mower running…again!
The problem ended up being a little deeper than I thought, and I hope this isn’t an indication of things to come. But I guess you can expect things like this from a near-20 year old Monkey Ward’s mower that had sat in the elements that past number of years.
The first problem started when I noticed a no-crank condition. I figured, ok, gotta be a malfunctioning safety-switch. While troubleshooting that, the starter froze up. (This was a good month or so ago, by the way.)
So, off comes the starter. Sure enough, it was stuck solid. Not sure what was wrong with it, so I decided to disassemble it. I ended up cleaning it up, checking the brushes, and reassembling it. I think rust between the output shaft and housing had caused it to glue itself together. It was working again.
Unfrotunately in the disassembly process, I very slightly cracked the plastic bendix gear that the tooth gear rides on. So, two start attempts later, that part grenaded. So again I was starter-less.
I spent the next week browsing online, and found an online catalog that I was able to find the correct model # of the engine. I found schematics with part numbers, and found the right part # for what I needed on the starter. I placed an order, and for $10 I was going to get the entire top assembly for the starter motor. To my surprise, their catalog and inventory system WAS correct and a few days later I had the parts!
So the other day I installed them on the starter. Also, I had previously gotten under the mower and “removed” the clutch safety switch from the safety switch circuit. So I was ready. Turned the key and the engine spun, it started, ran great – for 1.23 seconds.
I kept messing with it, and found it would only run if I put fuel directly in the carb. Wasn’t getting gas. Odd…I had just rebuilt the carburetor in September, and ran it a few times since then with no issues...gas was fresh too.
Well, finally I gave in and removed the carburetor. Took the float bowl off and found a huge mass of JELLO-like material inside the float bowl! I don’t know what that was all about, didn’t even smell like bad gas, something maybe bacteria related had grown in the float bowl.
So did another carb cleaning/rebuild and put it back on.
Cranked one more time, started right up and ran. Adjusted the carb and got it running good.
