Have I been using my weed trimmer wrong?

[JeepHead]

When I am running the trimmer, it's full throttle while it's actually cutting something. I have 14 year old twins and one runs like I do, and the other one just gives it enough gas to cut whatever he's cutting at the time. I find it amusing.

I know someone that does something similar to that. He drives with both feet, frequently using the brake and throttle at the same time. I'm not comfortable riding with him.

I had a work associate that drove like that. One day he, myself and our boss were in a company car and he was driving. The boss asked him why he was driving like that and the guy just gave hm a blank stare. Had no idea he was doing it.

Problem is, my Chinese replacement carb won't stay tuned. I can get it just right, then go trim the evaporation pond and by the time I'm done, it won't idle again.

I guess I just need to carry a screwdriver around with me all the time like Buckin' Billy Ray.

lol... I have the same issue with my Stihl BG56 blowers. The OEM carb's tend to fail by hydrolocking the machine with fuel, so I end up replacing them with aftermarket carb's when they innevitably fail. But the aftermarket ones never stay in tune quite as well, at least in some weather conditions. So yes... I often carry the little orange Stihl carburetor screwdriver with me when blowing leaves in the fall.

Two cycle engines are very susceptible to atmospheric pressure, humidly, and outside air temperature changes.

So it is not unreasonable to expect that some adjustment of the carb may be necessary when there are large changes in the above.

True. But to be honest, it's usually possible to find a spot on a leafblower that's good enough for it to run through the season, without constant fiddling. It's not like I'm blowing leaves in January.

I find that with the OEM carb, once you find a happy medium, they can be pretty much left alone until they flat-out fail. But the aftermarket carb's seem to require re-fiddling after each hour or three of operation.

Seems likely, but less excusable in these days of YouTube University

That's the problem so many SO CALLED experts passing along information that many times is in correct

I had a boss (actually two em') that drove like that, I would do ANYTHING to prevent having to go any place with either of them.

That's always been a problem, since the beginning of time, the Internet didn't create that.

The biggest differences between today and decades ago, is that with sources like YouTube, 1) bad information usually gets de-prioritized due to poor ratings pushing the better sources to the front, and 2) you actually have easy access to more than one source of information.

We use only enough engine RPM to cut the grass/weeds. No need to throw the cutting debris on you or any nearby landscaping. With 4 cycle trimmer engines and electric that have a variable trigger control running slower RPM is no issue.

The problem is with two cycle engines that will load up and foul the spark plug after a period of slow speed/load operation. When loaded up you must usually clear the plug every so often. We have a 24 year old 2 cycle trimer I run each mowing week during 26 week season over an hour continuous. Each 10 minuted I lift the trimming head from cut (usually when walking to next area) and go wide open throttle for 15 seconds to clear plug. It good for another 10 minutes of slow speed/load operation.

We much prefer the 4 cycle trimmers we have that never load up the plug with low speed operation. Trouble is we have 4 different locations and one location still has the 24 year old 2 cycle trimmer that works great like the day we bought it so no need to replace it. The 4 cycle trimmers have been an improvement for the way we use the trimmers.
