Where do you get off belittling people who are looking for information and A) don’t understand what some are saying and B) don’t have the knowledge to input what is said to them. Also never said anything about what Star said. You brought him into this conversation. Only answered your derogatory comments about me and yes was very competent and skilled at what I did for a living for 42 years. Can’t comment about your ability as I don’t know what you can or can’t do. People skills apparently are not your strong point but to each his own. That is why I came here for some help but all you wanted to do is be condescending to me any way you could. In my profession I had to talk to people who I was working for in terms of what they could understand. Some were more open and had the ability to understand and some weren’t so sometimes I had to dumb it down and talk English that they could understand but you haven’t the capability of understanding what some can and can’t understand.
You were hardly getting belittled.. lol.
People skills are not something on most of our priority lists.
I actually had a customer tell me one time after we had just loaded his mower back into his car after just unloading it because he decided he was going to take it somewhere... That I needed some work on my people skills.
I told him "That's not something I offer.
I do great work at great prices, and faster than every other shop in town."
In fact, I dislike most all of the people and the fact that I have to deal with any of them.
I am in it for the equipment. I like small engines at least some of them.
I want this equipment to run and run properly for a long time.
Some of the people are such idiots, abuse and neglect the equipment so badly, they don't deserve these pieces of equipment but I still like the equipment.
Anyways, to offer some suggestions to you, it's probably just coincidental.
It could have even been just the loading and unloading and stuff from bouncing things around because that can make a difference.
It could have also been what someone else said that you have a slight fuel delivery issue and when they set the RPMs a little higher it made that more pronounced.
As a general rule of thumb in a high percentage of situations, a surging is almost always lack of enough fuel.
And of course can be some other things but 85 Plus percent of the time it is this.
If your machine has a way to manually choke it, which most but the newest ones do, get it to where it is surging a little bit like that and then add a little bit of choke.
Typically when you get to about a quarter to a third of the way choked it will smooth out and stop surging and often speed up a little bit.
If it does this, it's almost a surefire sign that the main jet in your carburetor is slightly restricted.
You can worry about that from there or you can try some seafoam, or my personal preference, berryman's B12 liquid and pour some into your gas tank had a pretty strong concentration and then run it for a while and mow with it to see if it improves.
It often does.
It's also a good idea when you're running a cleaner and stuff like this too get it running well and then crank the choke all the way on a few times to where it's bogging down and stuttering. By doing this several times you're forcing the machine to suck a little harder through the carburetor jets and likely to clear something out more.
