Tiller woes
Last fall, I treated the tiller with some Sta-Bil, but by spring, most of it had evaporated. There was a fair amount of varnish in the carb, and it’s taken some doing to get it all clear again.
I have tilled three, maybe four times this season, I want to have the ground like flour when I plant. it’s pretty good now, I’ve been tilling in organics and grass clippings and compost for about ten years.
The tiller, which I got from Calvinis a Troy Bilt. it’s old enough it has like a four digit serial number. And today it wouldn’t start, for the first time in my life, and probably it’s life.
So I pull off the filter, and it’s flooded through and through. I’m amazed it turns over. I pull the float bowl.
The idle passage had been varnished up, but I had cleared that. The main passage had varnished up, but I had cleared that as well. There were plenty of places filled with varnish, and I cleaned them all.
You’d think, wouldn’t you, that fuel that had deposited varnish in so many places and clogged up so many things, would clog a pinhole in a float. But you’d be wrong. The varnish managed to completely clog a 1/16″ hole, and yet leave a hole open (and fill the float with fuel!) through a hole I could only see through the 20 power lens of my desk microscope.
So I did what all 8 year olds do, I put the damned float in the Weber grill, turned the grill on medium, and baked the gas out of the tiny, tiny hole.
Of course I lit it.
And then I put a drop of solder over the hole, and reassembled the tiller, and ran one more trip through the garden. We’ll see how it does long term.

LOL! BTDT…
Buy a can of gumout carb cleaner, (the liquid, not spray) and mix with your next few tanks of fuel. Sta-Bil helps keep the lighter stuff in the fuel from gassing off, but it won’t clean anything.
Every year when I put my motorcycles to bed for winter, (back when I lived in the peoples republik of new jersistan) I would put Sta-Bil in the fuel tank, run the engine for a few minutes, then turn off the fuel & run the engine till it stopped to get as much fuel as possible out of the carbs. I would use the choke to make certain I got out as much as possible. Seemed to work for me in solving the varnished carb syndrome.
I used to have to take small engine carbs apart all the damn time and clean them so they’d run properly. I haven’t had to tear down one carb since I started using Sta-Bil MANY years ago. That stuff is worth it’s weight in gold. I NEVER put gas in a small engine now unless it has Sta-Bil mixed in.
I figure I didn’t run it long enough to get the sta bil to the carb.
I’ve never used sta-bil or any other winterizer in my mower. ‘Course if you run it til empty, you don’t have to be that concerned. No gas, no sludge.
Sta-bil helps, but will still gum up a little anyway. Try putting SeaFoam in the tank each spring, crank it a couple of times, and let it sit for a day or two.
Never failed me yet.
HTH
Crucis, that’s ok on some stuff, but older mowers like mine, the gaskets perish when dry.
I like SeaFoam. I will try that.
Keep running the tank dry and sooner or later your going to suck gunk into the carb and have to tear it apart anyhow.
The last small engine carb I had to tear apart was because I ran out of gas while mowing. It’s a 22hp Kohler that has an electric solenoid fuel cutoff valve in the bottom of the float bowl. When you switch it on the solenoid engages and opens the cutoff valve to allow fuel to flow into the bowl. The trash blocked the valve opening and didn’t allow it to fully open.
I had good luck with SeaFoam in a Toro snowblower over the course of several summers. That girlfriend really misses me and my skills.
I’m not saying that my girlfriend was a Toro snowblower. Oh, no! That would hurt.
I’m pretty sure that’s a corollary to Murphy’s Law: stuff that clogs things up won’t prevent leaks.
Seafoam is the only thing keeping my snowblower going. One of the guys I work with puts a full can in the tank on every fill up of his old ford that he keeps stored most of the year.
All kinds of little fixes you can work on things. Once had the water valve on the washer crack, the one the hoses screw on to, and no money to get a new one. PUlled it off, dried it, worked epoxy into the crack and strapped it shut for a day. Thing worked wonderfully.
