Not two stroke fumes but it has been said that a engine is an air pump. The carburetor is equivalent to the lungs in that pump. I thought that getting the leaf blower started was going to be the easiest of my three gasoline powered machines to start. It is only about four years old, I have always ran good gas and I didn’t leave gas in the tank. I figured a shot of ether in the carburetor would get things going in short order. That would not be the case.

As I stated above, I confidently took the air cover off and opened the choke all the way. I sprayed a heavy shot of engine starting fluid and pulled the cord. The machined choked and sputtered and ran for about 20 seconds like it couldn’t quite get going. That would be with the choke on. Then, it immediately died when I opened up the choke on the carburetor.

I tried this again thinking things just hadn’t gotten up to operating temperature. This time I let the machine run two or three minutes under half choke. As soon as I opened the choke again, it died. This should have been my first clue as to what the problem was. However, I didn’t have any parts. It is not like I keep a bunch of small engine parts around anyway but I certainly was not not expecting to have to work on this machine. It has barely ever been used.

From what I could see, the fuel supply line had air gaps in it. I wondered if there was a break or crack in the fuel supply line. The priming bulb was full so in theory, even if the fuel was struggling to load the line, the delivery to the carburetor for running was adequate. I could obtain fuel line locally so I went about changing the feed and discharge lines.

The fuel line itself was hard and brittle. It did not seem to be broken. Nevertheless, while pulling the lines out of the tank, layers of the line sheathed off. In my mind, changing the line doesn’t hurt anything, it optimally shouldn’t be in the condition it was anyway. I crossed my fingers that it was just a line problem even though in my head, I really didn’t think this was going to work.

Guess what? My head was right. I pulled and pulled and I could only get the engine to run as long as there was starter fluid in the carburetor. I tried until I was getting to the point that my arm (neck) was bothering me, which doesn’t take that long. I resigned to having to do a more extensive rebuild. I wasn’t going to get that done while I was at the lake for a day or so I ordered an aftermarket maintenance kit.

It is tricky to plan delivery sometimes. I want to be home when it comes. I also know that we are not within the prime network at the lake. I have yet to try how delivery works, but it seems like I need to add another day to most deliveries. That is to say that I would not be here at the lake for delivery receipt and I may not be home either.

You can see what is included in the picture above. Since my lines were just changed, the carburetor comes with a new primer bulb attached, the air filter seems fine and I am not going to tear the whole thing apart to replace the spark plug, I am just going to swap carburetors. This cost $15 delivered.

Notice in the picture above, the O-ring fell out. I mention that so that you will be careful while doing this. I saw this too, I looked around and I didn’t see it anywhere so I thought my mind was just playing tricks on me and I put everything back together. Then I took the blower off of the bench and there was the O-ring. That cost me five minutes to take everything back apart and put the O-ring back on.

I gassed the blower up and gave it a shot of ether. It started after three pulls. The problem with the blower was something in the carburetor. If were up to me, I would take the old carburetor and rebuild it and then put it on the shelf for the next time I have these problems. What I am finding is that rebuilding small engine carburetors is a dead art. If you can buy an entire machine rebuild for $15, there is no sense in paying $30 for all of the gaskets.

One thing about living at the coast, small engine shops are not dead. We are far, far away from the logging heyday of the 1970s but there is still active logging in second and third generation forest in the Oregon coastal mountains. There is a saw shop only two miles from our lake house. Eventually when we get settled, I will visit and see if I can get a rebuild kit for the original carburetor. I am not going to pay more than $20 but I would be willing to spend more than an aftermarket carburetor just so that I don’t end up throwing the thing away. That being said, every man has a limit.

End Your Programming Routine: It was pouring down rain when I finally got the machine started. That is difficult conditions when trying to blow loose debris off the ground. Wet ground tends to cause sticks and needles to get stuck on the surface but I did what I could. With a giant fir tree in the front yard, I have a feeling that this blower is going to go from rarely used to most used gas tool in the shed.
