Another Engine
![image1[1]](http://lh5.ggpht.com/BillYork67/SGfpQVikXaI/AAAAAAAAAC4/3EFgc4Yeb8Q/image1%5B1%5D%5B3%5D.jpg?imgmax=800)
This is an engine. OK, so it's a picture of an engine. The great thing about engines is they generally work. Some years ago I saw the movie His Girl Friday. Rosalind Russel goes on a tant about Made For Use. The basic idea is that everything produced is produced for a purpose and for me, engines have a purpose. That purpose is to run. Frankly, I don't care much if they do anything beyond that.
This weekend's adventures included mowing the lawn. Usually this involves running the weed whacker, picking up the dog poop, and pushing the big mower around. If the grass is not too tall, this can take less than 2 hours.
This is my mower. The nice folks at equipmentlocator.com have the same mower so I snarfed their picture.
Anywho, the mower is about 7 years old. I bought it used from my friend Rick. It has needed only minor repairs since I got it. Much joy!
This weekend I had another opportunity to use my mower-fixup-checklist. (See previous blog entry). This time, it was fuel.
There were actually three things wrong with the mower.
- It's hard to shift gears
- The mower stalls after running for a few minutes
- It's hard to start.
The first problem was a case of mistaken belt routing. One of the drive belts was routed around around the wrong spindle. It was an easy fix once found.
The second problem took some sleuthing. The spark plug was clean and unfouled. The engine did not start when choked or unchoked - it didn't even sputter. I pulled the bottom off the carb and voila - no gas. The tank had gas so obviously the problem was somewhere between the tank and the carb. (You'll learn later that the problem was actually the operator.)
Having narrowed the problem, it was a simple matter of take-apart, and re-assemble, until the fuel resumes flow. The fuel line was pinched inside a clamp, I loosened the clamp and all was well. Now the fun part is that the clamp was mis-installed by me some months ago. The interesting question is why this was only a problem now. I suspect the fuel line has been swelling with age and the pinched section got more and more constricted over time.
With the fuel line repaired, the mower started on the 1st pull. Nice.
The third problem is still not resolved. I found out after trying to start the mower the day after the above repairs. It just would not start. Marathons take the gas out of my legs, pull starting mowers takes the gas out of the rest of me.
I suspect the starting issue is related to a dirty air filter cuz one I pulled the air filter off, the mower started right up. That's something to investigate further next weekend.

Small engines
* Gas
* Compression
* Spark
* Timing
For car engines, the timing is generally set electronically. For small engines, it is also electronic (or perhaps points/condenser) but the weak link is actually the flywheel. If the flywheel key shears - which it will from time to time - the timing will be way off and the engine will fail to run.
Anywho, here are a few of my current thoughts on small engines. Basically the typical 4 stroke engine works like this: suck, squeeze, pop, flooey. OK, maybe my grandfather explained it to me like that 30 years ago but it's a great visual. Air and gas go in, the picture gets compressed, the spark make it go "pop", then the exhaust goes out and we start all over again.
If you want to make a dead engine run, the process is, check for gas, check for spark, check for compression, then check your timing.
Most often, it's gas. Gas won't go in if you've got a dirty fuel line or dirty carbeartor.
Next comes spark. The spark plug can be really fouled - full of smelly gas or oil - but in general, if it's not broken, the plug is not the problem. The easy test is putting the plug on the cylinder head then pull the crank through a few times. If you see a bright blue spark, the plug is good.
If you've got gas and you've got spark, timing is the next thing to check. If the engine stalled cuz the mower hit a rock or it backfired before dying, the flywheel may have lurch ahead and sheared the flywheel key. Remove the flywheel (sometimes a non-trivial task) and check the key. If you need to replace it, make sure you get one of the same type - don't use a steel one if the one you took out was aluminum. Also, when it's all done, be sure to re torque the flywheel nut to the engine spec.
OK, so lets say all that is good, what if you still can't start? Now it can get tricky. You may have compression issues - these don't just show up suddenly though. You may have bad oil - bad enough to make the engine not start. Pretty seldom though. So, if you've got spark, timing, and gas, you should be all set. If not. something has gone dreadfully wrong and it may be time to seek help.
Speaking of oil, I noticed something interesting recently. If the oil in your engine is old enough to suffer viscosity breakdown, your engine will run poorly when it gets hot. Essentially, the thin oil blows through important seals and causes the engine to stall. Play it safe and keep your oil fresh - one or two seasons of use max.
Small engines are fun and they even more fun when on a go-cart and it's moving you along at 40 or 50mph. Perhaps I'll go get a go cart.

Electric Signs
- Mark out the shapes you want on the roofing material.
- Poke holes with an awl (front to back on the material).
- Turn the roofing over and poke the christmas lights through.

Mobile Phone Apps
Three steps:
- Get a USB Cable
- Install MotoMidMan (download)
- Connect and download
It must be that simple, even though it took me several hours to get the recipe right!
Also, if you want to author your own Java apps, use NetBeans 6.0 it really makes things easy!

Pizza Time!
- make dough
- roll out dough
- top the dough
- cook
- eat
The only tricky part is the dough. Of course you want the oven to be the right temperature and you want the dough to taste right and you want the sauce to be to-your-liking but those are details.
Here's how to make the dough.
- 2 cups water
- 2 teaspoons salt (if you like salt)
- 2 tablespoons of yeast
- 1/3 cup whole wheat flour
- 5-6 cups white flour
- mix
I basically mix everything but the white flour in a stand mixer with the dough hook for about a minute before adding the flour. If you want to do this by hand a wooden spoon and a big bowl will do just fine.
Add the white flour about 1 cup at a time until the dough starts to thicken. Then cut back to about 1/3 cup at a time. If you add to much flour, the dough will lose sticky-ness and fall apart while you mix it. If you don't add enough it will be wet and stick to the bowl and be hard to mix.
The texture of the dough is likely the hardest part. It has taken me years to get it right, you may learn faster though!
Next hardest is the cooking. I like to cook on a pizza stone with the oven around 500 degrees F. If you don't have a pizza stone, search Google and get one - they are worth it. We got ours from Pampered Chef.
With the oven at the right temperature and the pizza stone on a rack near the top of the oven, put the dough on the stone. This can be tricky. My favorite technique is to sprinkle a little flour on a pizza paddle (also well worth the cost), assemble the pizza while it's on the paddle, and slide it into the oven from there. One tip here is to make sure you don't push down too hard while making the pizza. A pizza that gets stuck to the paddle can make a big mess when you try to stuff it into the oven.
Now it's almost getting easy. If you want to keep it simple, set a timer for 3 minutes and close the oven. Then, once the timer goes off, take the pizza out when the cheese starts to bubble. If you want to be tricky and get a slightly crisper crust, move the pizza to another rack - one without the pizza stone - and let it cook for another minute or two.
The eating part is fun and the pizzas freeze and refrigerate well for several days.
Enjoy!

The morning after
Now with Scribus you can create great stuff like this in record time and for one low price.

I'd sure like to be able to paste images directly into scribus but it seems to require saving to disk first.
Did I mention you can save directly to PDF for sharing with all your friends?
Very nice.

A new blog
For that matter, don't you hate all software that crashes?
I just downloaded the freeware desktop publishing software called Sribus and used it for about 20 minutes. Then it crashed. A nice "EXCEPTION_ACCESS_VIOLATION" showed up and that's all she wrote. For that matter, that was all I wrote too, the program exited with no auto-save and no temp file and no dice.
It remindes me how much I really love commercial software. OK, not all of it works all the time but most of it works often enough to make it worth the $50 (or whatever it takes) to buy it. No, I don't want to spend $500 for Office professional but I'd happily spend $75 to avoid crashes and get all the perks.
The sad news is I can't just spend $50 or $75. It looks like $150 is the price point.
OK a quick search of Amazon says I can buy "Print Shop" for just $10 but that just scares me. Perhaps it's worth the $10 if I don't get crashes.
Something to ponder...
