When I started cuting wood this spring, my 192t had poor trigger response. The saw would idle just fine but would balk or out right die when I gave it the gas. I took it into the shop and was told it needed a new carb. It is still doing the same thing with the new carb. The screen in the muffler is clean. If I play with the trigger I can get it up to speed and runs fine. Is this a carb tuning issue?
Erik if the shop put on on they should have ran it and tuned it. Usually the bog you describe is the low screw. If your saw has the adjustment marked on it you can use those as a starting point. GENTLY turn the screws in till they stop. Then turn out the number of turns marked on your saw. After you get it running right you may have to adjust the idle setting screw. If you have the manual it will tell you how to do those adjustments.
Messing with carb adjustments is something I have not done yet and I am a bit leary of it. I will check out the manual. Thanks.
I used to be the same way. When you turn the screws in all the way just watch how far you turn on the way back out. There are some YouTube vids that will give you the general idea. If nothing else take it back to the shop that put the carb on and tell them you wanna watch how to do it because it's Stihl not running right.
I’ve got an 020 in line for the bench. I know little about the T handles. But i would think if it was a problem with the carb tune it should be minor adjustments from this, which is just a low tune. I wouldn’t touch the LA since idle doesn’t sound like the problem. Sounds a little like air leak to me. But try the carb first
I’d try it both ways Start at 1 turn from soft close. Then an 1/8th ccw, open Then an 1/8th cw, closed Decided how you like the response. And tweak from there. But because it seems to do better when warm, you may need to wait between tests. That’s why it sounds air leaky to me. Gets better when hot when things swell and close up
Your H should be 3/4 turn CCW from seated and L 1 turn CCW from seated Erik. These are the factory recommended settings. Like M2theB said some additional tweaking may be required.
I took the saw back to where I had the new carb put in and got it retuned. It acted up for him as well so he knew exactly what the problem was. He said it was a bit lean on the low side. I will put it through its paces the next time I am in the woods. Thanks for all of your suggestions and help.
No he didn't. He was extremely busy. I don't think it took him more than a couple of minutes to do a retune on it. I am glad he got it running better than it had been after the install of the new carb. I would like to spend a bit of time with someone who would be willing to give me a lesson on carb tuning.
I took it back to the shop for a retune and tried it again in my woods. It behaved itself for a short while but then it was back to doing the same thing. Hit the trigger and it boggs down or even kills. To get it to go WOT requires babying the trigger. Restarting the saw is also a lot harder now after it warms up. It used to take only a quick jerk but now it takes 5-6 tries. To recap iot has a new spark plug, new fuel filter and new carb. What else might it be that is causing the troubles. I run 93 octane non ethanol gas.
Check the muffler screen first then go through the fuel system. If the air filter is clean and compression is good, it should run.
I talked to the tech at the hardware store about the continuing problems I was having. He didn't know what else to try other than maybe buying a new saw. I took it to the Stihl dealer I bought the saw from and asked them to look at it. After giving it a bit more gas on the low side, a full half turn, it seems to be back to normal. I won't call it fixed until I try it out actually cutting wood and using it like I normally do. Fingers crossed.
Follow up story. Glad for the wearing masks mandate. I continued having problem with my saw so I took it to the dealer where I bought it. I told them I had been having bad trigger response and hard starting at times. I left it for them to figure out what was wrong with the saw. I got a call today saying the saw was good to go. All they had to do was tighten the spark plug When I got to the shop the tech told me the plug was only in a couple of threads. Good thing I had a mask on so he didn't see the egg on my face. Live and learn.
Glad for ya. Sounds like the ''tech'' at the hardware store, wasn't quite up to speed on completing the job.
