Every day is a new lesson, some easier to swallow than others

I spend a lot of time telling my guys at work that what makes the difference is attention to detail and that they should learn something new every day.

Well, I should have listened to that more on Friday.

Not only did I get the Bell setup good friday (did I mention how happy that made me?) but I also got the Gun Cabinet mounted on the wall and M filled it with guns, AND the third thing I wanted to get done was repair the Weed Trimmer.

I know, thats the first I have mentioned that so let me back up

A couple weeks ago when I was out of town D told me the trimmer would not start.  It had worked and then would not start.  It is a Troy-bilt TB425CS 4 stroke engine with the changeable attachments.  So when I get home I look at it and sure enough, no start.  I do some digging on-line for some ideas and start taking the thing apart.

1) Look at the flywheel to see if it has shifted and the timing is off.  After getting the thing down to nothing I confirmed the flywheel was fine.
2) Confirm spark.  D helped me and we did a spark test against the motor (shocking her in the process) and confirmed it had spark.
3)  Looked for a stuck valve which is apparently a common problem with these.  Nope, valves are fine.
4) After messing with it for awhile though and removing the spark plug multiple times I realized the plug was not wet and I did not smell gas.  I took the carb apart and it did not look good, but it was hard for me to confirm it was the problem.  Then a light bulb came on in my head  (yes, it does happen every now and then)  Using a spoon and a funnel I put about a tablespoon of gas in the cylinder through the spark hole, put it back together and cranked it.  It ran for a couple of seconds and then died.

That confirmed that I had air, spark, etc but no gas and my problem was somewhere in the carb.  I know gas was getting up to the carb because it has the priming bulb on the side of the carb and I could use it to pull gas up to the carb and push gas back to the tank.

I went looking for a carb re-build kit and found I could buy the whole carb for 30 bucks so I decided that would be the best thing to do.  I also bought a new gas tank and hoses since I had broken the others lines in the process (on purpose)  They were pretty old and tired anyway, so it was worth it.

so back to Good friday, I had 2 of the 3 projects I wanted to get done for the whole weekend accomplished, and it was only Friday.  I was feeling good, confident, etc and was aching for the fedex man to deliver my box of parts to the front door.  When it was finally delivered I went to the garage to put all the new parts on.   I bolted everything on, put gas in the tank and the thing started on the second pull, just like it should.  It ran fine, no issues, everything sounded great, I was smiling the biggest smile you could.  I stopped engine and went and grabbed an attachment to bolt on it.    When I went to start it again, the pull cord spun way too easy and I heard something spinning inside for a long time,  the engine was not turning.

Of course the smile I had turned away rather quickly.  I take the attachment off and walk the trimmer back to the garage and start taking parts off it.  Sure enough when I get the pull starter off I see the flywheel is spinning freely and sitting there in the bottom is a rubber cover.   I look around and that rubber cover is for some of the wires that come out of the engine.  The rubber cover is gone from the hole they go through.  Obviously the rubber fell inside, jammed the flywheel, I pulled the cord, broke the key right off the flywheel.

so off I go to order more parts for the trimmer.

Hopefully this week I can get the flywheel in, pay attention to the detail, learn from my mistake and get the trimmer going again
