Just checking in to calm those who may have been concerned about my health and welfare after that marathon run to Bremerton a couple of days ago. I’m just fine. For those of you who may not be concerned about my health and welfare, for any reason, that’s OK. Lots of times I’m not concerned about my health and welfare, either which usually ends in a trip to the emergency room for stitches. You would think it’s because I’m careless, which is definitely a contributing factor, but the main reason for my accidents is because I’m concerned about your health and welfare all the time.
Makes me lose focus.
You’d think I’d learn, right? Especially after all those lectures I get about being more careful. Oh well, I generally mend OK and the many scars I have are like the rocks I pick up on the beach. I know what I was doing when I got it, and where I was at the time. They are memories.
Now I’m happy to share the good news that I’ve successfully earned the right to call myself a Small Engine Repair Guy (SERG). Remember that mower engine I tore apart last week? Well, today I got it all back together, didn’t have any engine parts left over, and it runs like new. I’m so happy! There’s more to this story, of course, and it’s another one of those frustrating trips, but the end result was worth it.
It all started yesterday morning when I took Diane’s truck to Emmert Motors to discover why the backup lights are always on. I may have mentioned that I semi-resolved the problem by taking the backup light bulbs out. It was tempting to just leave it at that and not bother taking the truck in for a checkup. There was always the chance of a more serious underlying issue, however, so I drug myself off the couch at 0745 so I could honor the 0800 appointment.
I checked in with Tom, gave him the keys and the backup light bulbs, then went to talk with Steve for a while. I always do that when I visit Emmert, visit with Steve. Sometimes I go there just to visit with Steve. He’s my favorite car salesman and he always has candy on his desk. After a short visit I went to the lounge area and fiddled with my iPad until Tom appeared and asked me to follow him. I did.
He took me to the garage and demonstrated for me that the backup lights were functioning just fine. He believed me that they were on for 2-3 days, like I reported, but they were working fine now. He just said to bring it back if it happened again, preferably during the failure. So, apparently I fixed it by taking the bulbs out. Go figure. But, we’re keeping an eye on those things, believe me.
After that morning trip, I returned home and at a sandwich in preparation for tackling the lawn mower engine. Diane insisted. She was preparing for her trip to the court house to finish ups some community service she was assigned. No, wait. That was a couple of weeks ago. She finished her community service. She was going down to join her friends on the counting board for the current ballot. Yeah! That’s it!
After the sandwich I attired myself in some of my better dirty work clothes and made my way to the church. It was raining more than not, so I was planning on getting wet because the lawn mower is stored in a small shed with no room to work on anything. As it turned out, though, the sun shined most of the time which allowed me to sit in the wet grass to do the majority of my work which was to put everything back together.
I got busy by first scraping off the old crank case gasket using a starter shim I happened to have from the last time I installed a starter on the old ’68 Chevy truck. I meant to take a chisel or knife, but forgot, but the shim seemed to work just fine. Just took a while. Made my hands sore, too.
Then I cleaned up all the parts as best I could, considering the circumstances, and went about the process of discovering where all the parts, bolts, and screws went. That really wasn’t a huge challenge because all you have to do is match up bolts to the holes they fit in. For instance, there were 10 bolts holding the crank case together and they were long ones. They wouldn’t fit anywhere else. This was pretty much true for the entire reassembly process. The tricky part was the new cam shaft which required me to match two little dots together on the cam gear, and the shaft gear. It took a while, but I did it. It just didn’t happen as easily as I had anticipated. From the YouTube video I watched it seemed to be pretty simple.
When the last bolt was tightened, I set the engine in the proper place on the mower frame and manually turned engine over to see what happened. No way was I going to try it with the starter first. No sir! Good thing I did, too, because it spun around nicely for about 1.5 rotations then went “clunk” and stopped. Turning it backwards the same distance produced the same result. So, I figured I must have missed the mark when lining up those two dots. However, I’d had about enough small engine exercise by that time, called it quits and went home.
I was only on the couch for a short time, recovering, before Diane returned home, released from the Counting Board for good behavior. We went through what has become a daily routine of “what do you want to eat,” and “I don’t care,” then Diane got a couple of egg rolls and some rice. She suggested that I eat the last Kung Pao TV dinner, which I did, along with a couple of egg rolls of my own. We have a large box of them in the freezer. It only takes 3.5 minutes for heat a couple of them up. It’s 4 minutes for the TV dinner.
This morning I got up with that stupid mower engine buzzing around in my head, mentally preparing myself for the necessity of dismantling it again to see what I did wrong.
As I was pulling the mower out of its little garage, it started pouring rain so I just picked up the engine and carried it into the mower space and went to work.
I took out all the bolts, removed the crank case cover and stared intently at the new gear I’d installed yesterday with great care. It only took me about 30 seconds to see that I’d not matched the cam gear dot with the crank shaft gear dot, but with a gear on the crank shaft that was just different that all the others. About 20 teeth around the corner was the little dot I’d missed. I firmly believe that the folks who build Briggs & Stratton engines make their crank shaft gears like that just to fool folks like me with the intent of getting them to try cranking it with the starter before checking to see that it works. Well, I previously proved that I didn’t fall for that tactic. No sir! No, I didn’t get it right the first time, but I didn’t break anything, either. All I wasted was a little time.
I released the rocker arms from the cam shaft push rods, turned the engine to the spot where the dots would line up, slipped the cam shaft into place just as easily as the guy on YouTube did in his video. The crank shaft cover went on just as easily, like the video, and things just fell into place. All those bolts and nuts went back like I had been doing this kind of work for years. Once together, the engine turned freely, as it should. The little rocker arms danced up and down just perfect, the carburetor almost attached itself, as did the exhaust pipe. When I looked around my work space, there was only one piece left, an odd looking bent wire thing that I hadn’t removed. It had fallen off something when I took the engine apart and I had no idea if it was even part of the process because I’d just found it laying in the lawn.
I had a feeling it belonged somewhere around the carburetor and studied that area for a long time before giving up, cleaning up, and driving to the Scappoose Sears store to look at the new mowers and see if I could find something similar on them. No one questioned me as I wandered around the dozen or so mowers on display, lifting the hoods and staring intently at the engines. I can only surmise that they didn’t want to take a chance they’d have to talk with me because I was pretty ratty looking, even though I had arrived in a pretty nifty little car.
This investigative effort proved to be a waste of time so I went back to the church and dialed up Bing to see what I could find.
Finally, I found a reference that gave me the answer. The left-over piece was the part that chokes the engine when the accelerator lever is pushed to the maximum level. So simple. Well, now I know and think I could repeat this job quite easily, without YouTube, in a fraction of the time I’d spent learning.
Once the engine was together, I bolted it to the frame, installed the pulleys, connected all the wires, and whatnot, then sat in the seat. I didn’t try starting it right away, but just sat there a bit, resting. Actually, I was casting good mojo at the engine, willing it to turn over and run. Apparently mojo works because when I turned the key it fired right up and ran like a top. I only let it run for a few seconds before realizing that I’d failed (again) to replace that 48 ounces of oil I’d drained from the engine at the start of this process.
Withe new oil installed, I started it, and ran around in circles in the little yard next to the shed before putting it all away. There would have been more circles, but it was raining pretty hard.
I’d done it! I fixed the mower! The small engine repair guy said he could do it in 5 hours, at $80 an hours, plus parts which I paid about $80 for. So I saved the church $400, minimum. All it cost me, in addition to those parts, was some of my time.
To put that in perspective, considering I was making about $40 an hour when I retired the second time, had I been charging for time it would have cost the church about $480 in time plus parts.
Good thing my time is free, right?
In my eyes, that time was well spent because I’d learned a new skill. I’ve busted a lot of those little engines over the years, but had never been compelled to tear one apart to see what makes them tick. That’s odd, too, because I generally tear everything apart right away to see what’s inside, but not engines. Turns out they are actually pretty simple and made me realize that had I been a little braver, or inquisitive, I could have saved a lot of money over the years by fixing those things instead of replacing them.
Now I’m a mechanic. Really, I am. Once my hands heal up, and my sore muscles go away, I’m pretty confident I can talk someone through this process should the need arise.
All that’s missing is the hood. It’s all good.
