If you're talking about the rubber boot covering terminal, has nothing to do with starting. But when you resat the boot, you may have accidentally tightened the terminal connection. I'd recommend you pull off the boot and check the connections for tightness and corrosion.
You really need to measuse the batterys CCA rating. A bad battery can still show near 12 vdc before starting, and then drop dramatically during starting.
Really sounds like your battery is near its end. Try pulling the caps off (usually under a large sticker on top, even maintenance free...
In my case, I was never able to fix it. The frame took the slight warp to the left. Tried repeatedly bouncing up and down on the right, nothing. Steel too thin on frame. Sorry, no help.
Blades out of balance? Spindles worn? Deck hanging hardware bent or worn?
Tractor frame leans to one side (I had this happen to a tractor i owned, tractor leaned to the left about a qtr inch because i always mounted the unit from the left side. Body weight all on one leg put too much stress on...
Getting back to the OP's question, (and I'm the first to admit that I know next to nothing about it), the purpose of zinc in oil is to work as an anti oxidant. (It helps prevent the oil from breaking down and extends its useful life).
You may be able to find the parts you need for your mower on a site like this (could always post your needs and see if anyone responds)

The deck is raised and lowered (from transport position to mowing position) via a lever on the right fender (next to the seat). And its a bitch to use, very hard to unlock. Lowering go quick, raising requires a good jerk to get the momentum needed. I liked an old tractor i had, forget the brand...
That's complete nonsense. You don't understand how these tractors work. Both Regency and Broadmoor have manual lift levers to rase and lower the deck off the ground.
The electric lift on the Broadmoor only adjusts the height of the blades inside the deck. On the Regency its done by manual...
Several areas.
First is the tires are too small, makes the chassis too close to the ground. This make it impossible to get the mowing deck off the ground completely. When going from driveway to grass, it gouges.
Also I part my tractor in a shed and use 2x8's as a ramp. This makes it d.r.a.g...
All this talk about carburetors, but what about the op's real problem? I don't know the answer, but found it interesting that everyone skipped over his real problem.
Yup, all good mate, but its the sneaky, kangaroos ya gotta watch out for. Little buggers sneak up on ya and ... pow.
Deadly.
Hey, I seen Crocodile Dundee, three times. I know all about those roos.

Afraid I'm going to agree with the concensus. You hit something rock solid and 'tore' the deck. Started at the outboard edge and continued when the thing you hit failed to yield. The giant scrape at the side is proof positive. To me, it doesn't appear to be a failed weld, rather the metal tore...
Don't think they would fit the shaft. If I remember correctly, the upper blade has a larger hole, so the twin blade design would not fit the shaft of the single blade design.
Since the year 2000, almost all car manufacturers started using the soy-based wiring insulation.
In that case you would be driving a car over 20 years old. ?

Mice and rats hate peppermint and cinnamon oils. This brand claims to last all winter (i haven't used it but tempted when current supplies run out). Just put a bag or two near your equipment...

The case is not as straight forward as some would seem. The kid is claiming seld defense because its all he can claim. He can not deny he shot three unarmed people at close range. And he can't deny he intended the kill them.

Chuckle. Couple of years ago I bought a new Simplicity garden tractor. It ran ok for a few days and then wouldn't idle.
Talked with my dealer and learned he had put Ethanol gas in it to display it at the county fair. Afterwards it had sit for a few weeks in his lot.
Tried Sea Foam and it...
And as others have recommended, think of replacing the cable assembly. I don't know what exact model you have, but if you look on ebay, you'll see that replacment cables run around $10 with free shipping.
If you post your model someone can look up the part number.
Hard to find used. Here's a site that details to parts and part numbers. May be able to piece one together from you you have as a starting point.

My previous tractor wad made by AYP (same as your dad's Craftsman) and I had a simular problem (have yard professional rolled every spring, but turns to bumps and ruts anyway). When it died I bought a Simplicity and this seat is heaven compared to the old one. I still bounce, but its much more...
This is new, but not too bad of a price. (Or do you need the frame as well?)

When you say "small roller" are you talking about the drive wheel on the left side, or something else? (Does your Honda HRD 536 have a stripping kit installed (didn't see a small roller in the owners manual).
Is it frozen in both forward and reverse?
You may not want to hear this, but
Years ago (we're talking the 1960's) I attended tech school in Indianapolis. I landed a job working for a small TV and radio repair shop, downtown. Guy had been there for years. I got the easy repairs, replace a tube, install a new capacitors, etc. After I got...
Just to clarify, when engaging the drive, does it pull the engine down (acting like the drive system or transmission is stuck) or, the engine stays strong and the drive system refuses to transfer the power (ex. belt slipping or idler spring weak) ?
Oil will slow or prevent rusting of a steel deck, but oil is stick and doubt it would prevent wet grass from sticking.
Nothing really works very well (or everyone would be using it and the manufacturers would recommend it in the owners manual).
Perhaps a paste wax, Caribana is long lasting...
I would recommend adding Sea Foam (at 2x normal dosage) to your gas. Run the engine to draw the mix into the carburetor then shut off and let it soak. Sea Foam will eventually dissolve the clogs in the tiny jets in the carb (what i believe is causing to problem. Probably due to the use of...
If the instructions don't describe when one or the other is used, try calling Briggs at (561) 880-4022 and ask them. (8-5 est). If anyone knows, its them.
From what I've read, science has a very good idea of the condition of the earth during the time when millions of buffaloes roamed the plains. At that time there also trillions of trees covering the planet, absorbing the excess CO2.
The record was written in the Artic ice. Core samples clearly...
Glad you found the problem, but I'm confused. How does a broken ground to (is it both coils?) cause a parasite draw? Why did the engine run on for 5 seconds and then stop? A broken ground would keep it from shutting off completely. Wouldn't it?
