We have ignition, and lift off!

Well…kinda. So I finally got the tiller running. I had told my wife and anyone else around that I knew what was preventing the engine from running was going to be something so simple, I was overlooking it for that very reason. I had disassembled the carburetor at least a dozen times, cleaned it just as many, and still no power. I knew it had to be something wrong with the carburetor also, since even with my limited mechanical knowledge, I knew the engine was working. When I sprayed engine starting fluid into the carb, it would fire a few times until the fluid was consumed. So the spark-plug and cylinders were working fine, it just wasn’t getting gas. In exasperation on Sunday morning, I had declared to all that would listen to me that I was giving up and would just sink the money needed to get it repaired. I knew it would really suck, since after buying a new home and still paying a mortgage on our other home that isn’t rented out yet, we are kinda cash-strapped. Well, dedication…or maybe just plain stubbornness drew me back out to the garage again later that day. My neighbor, who I will just call “J”, stopped by after most likely hearing the string of curse words coming from my garage. We sat there and talked about how I still couldn’t get the damn thing running, and that it had to be the carb, since it would run just long enough to consume the starting fluid and then die. My other neighbor “R”, was nice enough to take my carb and use his air compressor to try to blow out any debris from the carb valves. It looked like everything was clean, I had run a wire through all the fuel valves countless times. It was good knowing that I wasn’t crazy, since they were telling me what I was expecting this whole time. Well, “J” and I headed back over to my garage to look at the tiller again. While we were sitting there, I had a stroke of genius (luck???) This whole time I was looking at the carburetor and wondering why fuel wasn’t getting into the cylinder, but there was one part that I kept overlooked. To understand why I missed it so many times, I’ll post some pictures of the carburetor. The carb itself is pretty simple. Air intake, the main channel, fuel bowl, output to engine. Fuel comes into the bowl and fills it up, a needle and float stops the bowl from overflowing (that’s what caused my leak in the previous post, the float was stuck so the fuel intake valve never closed properly), and then fuel goes into the bottom of the bowl, up a shaft and up into the main channel to mix with air and then goes into the engine. If you look at the pictures carefully, you’ll see a little notch in the shaft. That’s where I assumed fuel would go through to get up into the main channel. Well, one thing was bugging me, that’s also where the screw that holds the bowl goes. It kept nagging at me, the notch would let fuel in, but not with the screw in place. I finally picked up the missing piece of the puzzle, the screw itself. I took a good long look at it. Just a normal screw, one thing that was weird about it was it looked like there were two pits on the side of the screw and on the bottom of it.

“…no, that couldn’t be it, could it??”

I looked at “J” and asked, “you don’t suppose fuel goes through this screw, do you? “. He took a look at it and tried to blow into it. Nothing.

Well, wouldn’t hurt to try something, so I took the screw and submerged it in carb cleaner. I swished it around for about 30 seconds and noticed something magical (not really, just pretty cool), gunk was coming off of the screw….a LOT. So I took out the screw and got a small length of wire and tried poking it through one of the pits on the side of the screw. THE DAMN THING WENT STRAIGHT THROUGH!! So then I look at the bottom of the screw and poke the wire though, it breaks through a layer of grime and goes right to the part of the screw where the side holes where. The screw was hollow!! The fuel goes into the notch on the main shaft, INTO the hollow screw and up to the main part of the carb. I give the newly cleared out screw another soak in the carb cleaner and then put it all back together. We both kinda held our breath as I got ready to put the starting cord, since this whole mess really got us fired up. I gave the cord a pull…

IGNITION! The engine started up on the first pull. I looked over at J with wide eyes…Holy crap, it works! I ACTUALLY fixed something with moving parts in it! We let it run for a few minutes and then finally cut it off when it seemed pretty apparent that it was running beautifully. I thanked J for all his help, since it was technically “we” fixed it. I can’t remember what he said, but it was right before I picked up that screw and took a look at it, so it had to have been something that got me thinking about it. Well, after the handshakes and back slaps, he goes back home and I get ready to start the actual work gardening, the tilling itself.

I shift the tiller to “forward” and squeeze the drive control bar. The tiller pulls forward about three feet….and then stops. “hmmm, that’s not right”. I shift to neutral and then back to Forward, and pull the drive bar again. Nothing at all. I shift to the “forward tilling” gear and try that . The tines spin (yay!) but still no movement. Now, for those who haven’t seen or used a tiller, it’s like a very large push mower. With large push mowers, many of them are self-pulling so that you aren’t throwing out your back trying to push the mower around. Without the self-propelled aspect of the tiller, doing any work with one would be very difficult (more like impossible as I was to find out).

“Well great, I got the engine working, but now my transmission is F’ed up?” A tiny, simple carburetor got the best of me for 3 weeks, how in the hell am I going to overhaul a transmission? Not only that, but the parts for the carb were $70, anything other than screws in the transmission STARTED at $50 each. It is going to get expensive fast if, when I open up the transmission case, it looks like how I think it’s going to look. As I went running back to Google to find out more about the transmission, I found out that the craftsman tillers have a major flaw. There is a gasket (or paper donut as some people online described it) that when water pools in the tiller, when it is left outside perhaps, it dissolves away and lets water right into the transmission. Well, water and metal don’t get along very well, and you now have rusted out gears.

“Crap, taking apart a transmission was not was I was expecting, and this is going to take longer than 3 weeks”. The entire growing season is likely to pass me by. So I got back out and try shifting into neutral. I gave it a push and the tiller rolled along, as expected. “Well, that wasn’t too hard to push”, so I shift to “forward tilling”. The tines start spinning and give the tiller another push. It rolls a little as I push it. Now, I’m pretty sure the wheels should be engaged to the gears, so the fact that it’s acting like it’s in neutral is NOT a good thing.

….but…if I can push it while the tines are spinning….maybe I can just muscle the tiller around like a non-self-propelled mower. I push the tiller to the back and start on a row. The tines dig into the ground and start busting up the hard layer of sod. “Sweet, this isn’t so bad” Wrong. Only a few feet into tilling, I’m starting to sweat. It’s HARD work pushing a tiller while it’s chewing up dirt and weeds. Then the tiller started rolling back into the tilled dirt behind it, creating a little ditch. I found out quickly that trying to push the tiller out of the self-created ditch was getting more and more difficult. I gave up in exhaustion and dragged the tiller out of the row that I was working on.

Wow….one half of one row. I had made it 10 feet in 45 minutes, was thoroughly exhausted, and my back was killing me (previous injury, that story is going to be a whole other post). Wow, so I only had another 790 feet to go. I slowly pulled the tiller, which felt like it weighed at least 1000 pounds at this point, back to the garage. I sat around the rest of the night wondering how much it would cost to have a transmission repaired, but also relieved that I didn’t send the tiller to be fixed, only to have the technician say “we fixed the tiller, it was a clogged screw, that’ll be $300”.

The next morning I woke up with a crazy idea, much like I do every single day. It’s tough being me with all these wonderfully crazy ideas running through my head, since my loving wife usually steps in and prevents me from injuring myself, lighting myself on fire, getting myself blown up, or just plain dying. Well, the crazy idea that morning was in the category of the “just crazy enough to work”

To digress for a moment, I have two types of crazy ideas. Sober crazy and drunk crazy. The drunk crazy ideas never get an audience from my family, since they’re usually along the lines of “Maryland law states you can’t discharge a firearm within 150 yards of another resident, without their approval….wouldn’t it be AWESOME if I went door to door asking the neighbors if it would be okay to shoot at clay pigeons in my backyard. They’d of course be welcome to join me, it would be fun!” Luckily most of those ideas are lost in my hangover the following morning. Now, the sober crazy ideas are “crazy like a fox”, and involve more brain cells since they aren’t drowning in rum.

So, back to my sober crazy idea. Since the tiller engine runs, the tines spin, and I can move the tiller like it’s in neutral, I just need a method to pull/push the tiller. Human power just wasn’t cutting it, so what about getting a length of strong rope/chain and hooking it up to the back of our CR-V? Then with my wife drive the car, and me working the tiller, we would just need to work out a start/stop communication method. I figure a whistle would work, with one tweet to stop and two tweets to go. Then just blowing on the whistle we could use the power of the car to get the tilling work done, and then after that, I can take all year to fix the transmission myself. There’s plenty of room where ”the farm” is being set up, so driving the car back there won’t be a problem at all.

A few days later, I was talking to J about my idea, and he just looks at me kinda confused and says, “why don’t you just rent a mule?”

Rent a MULE? I know I’m in the rural-suburbs here in Howard county, but I didn’t know you could still rent a friggin’ mule! I didn’t ask him where one could rent a mule from, but I guess I’ll keep that in mind if towing the tiller with the CR-V turns out to be a disaster, like most of my sober crazy ideas end up. I’ll be sure to post pictures of that this weekend if I succeed in convincing my wife that it’s a good idea. The thought of fresh veggie might entice her enough to consider it.
