Echo PAS-280 trimmer won't run at all

My client usually has me work on his tractors, trucks, etc. but this time gave me his Echo PAS-280 trimmer to fix. It had worked well, then sputtered. When he brought it to me, I gave it a shot of starting fluid and it fired but wouldn't stay running.

Aha! Carburetor.

Took it home and I can't get the least sputter from it. Checked plug, it's clean, dry, heated it and dried it out, and it sparks nicely when grounded on the bracket. But give a cough, it will not.

I plan to replace the plug, knowing that some defects will keep a plug from firing under compression. But really? I've fixed dozens of gas engines and this one is behaving very badly. My knowledge has failed me..it should at least sputter when given a whiff of ether, choked or not.

Wouldn't hurt to try a new spark plug and also make sure spark arrestor screen is clean.
So did you clean the carb?

So, why won't a working plug give at least a pop with a bit of ether? Always has for me, as a test for spark, and I've been working on mowers and saws for 50 years.

got new plug, will try.

Yeah usually get a pop off if there's fuel and spark.

Replacing the plug did it. Even though the plug fired reliably while hanging on the side grounded to the engine, it didn't fire when installed.

I replaced the NGK plug with an Autolite 2976 Copper core. In older tractors, the copper core wires and simple plugs are best. Somehow resistance wires and plugs with the high tech core design aren't as robust.

Who needs resistance/supression while running a weedwhacker? Listening to the radio when working?

Well, I always wear ear protection with the radio. I need the Resistor plugs.

For best performance and ease of starting i always use NGK plugs in all Japanese equipment.

Being a amatuer radio operator I am always getting complaint that I am the culprit messing up radios and tvs.Even it was the electric that was doing I still got the blame.

After I started using antennas that people don't recolonized as an antenna the complaints went away. Some of have asked what I was using for antenna and I say my frig. It a real conversation piece when I am using my BBQ grill as an antenna.

Please for the peace of the neighborhood use resistor plug. They reduce radio inference.

LOL Do I need a tin foil hat when anywhere near you?

I've been using my PAS 280 daily for a month as a professional user. It is more powerful than my previous Husquvarna and starts reliably, but I do not like the design of the trimmer head nor do I like the small shield. The head does not auto load easily, which means I still have to fumble with side tabs to remove the spool which is difficult on this machine. The spool is difficult to tell which side goes up, so if you load it incorrectly, the line does not feed out when bumped during use. Even when loaded correctly, the line does not always feed out. I have to bump the machine very hard 5-6 times before the line feeds out, which costs me time, and I feel will wear on the machine. The shield is much narrower than the one on my Husqvarna, which means more debris flying back at me, so a face shield is a must, safety glasses don't cut it.

I installed the Speed Feed head after the original flew apart and parts went awol. The narrow shield is much easier to deal with in tight areas than the one on my previous Stihl but yeah, I get pretty dirty fast.
