People say that but iv been doing this for 25 years and never had that problem. I suppose if you make it have more magnetism it could compensate for a failing coil with too much resistance that may be why it works for some people.

I said that because I had that problem with a mixer engine some years ago. I went through everything trying to solve the spark problem.

I have "results" removing the center tube thingie and blasting with cleaner and air.

Guessing air pressure can do the same in place?

I have questions. Here is the carburetor:



The float bowl takes an Allen wrench and is inset into the bowl. No way to remove it using my tools. I am just a couple of steps from getting the carb off.

Question: It has two wire control rods (choke and throttle I suppose) which are easy to remove by simply tilting the carb. However, they require tilting in two different directions. When one is removed the other will be cake but I don't want to bend either one. One of the wires is long, thin and has bends in it already. I think this wire will bend 45 degrees without damage, correct?

Nevermind. Carburetor is off. The removal process takes about three seconds. I need some carburetor cleaner. Looks like a new carburetor is $20 but it also looks like this thing is pretty simple.

Squirted the carb as good as I could w/o disassembly, no worky. Ready to invoke the $10 new carb solution and I watched a YouTube video disassembling this carb. followed the procedure. Lawn mower runs now.

Now that I can remove and disassemble the carb easily, I think gas stabilizer is still a better idea.

Thanks to all.

For $10 sounds like a quality item.

Those are easy to clean. I just did two of them. you pull out the white plastic thing in the bowl with pliers and thats the jets. I usually wash the whole carb in the sink with hot soapy water first then go through and spray everything out. Good idea to drain and wash out the tank while you have it off because thats probably why it got clogged.
