Stihl MS192tc Starts Easy But Bogs Down And Won't Rev Up! Diagnosis and Repair.

In this video I fix a Stihl MS192TC. It starts up easy but bogs down. I go through the saw and figure out what is causing this issue and fix it.

you did a great job many people take apart and don't even clean the parts you did a very good job

[@harrybalzonya7296]

I don’t often sit all the through a 16 minute KZbin video but I did on this one. I would have immediately went for a carb rebuild right off the bat, this gave me other easy troubleshooting tips that I wouldn’t have thought of first. Good job buddy, thanks.

[@MarleyJaxGarage]

Thanks for watching man I really appreciate the comment!

[@williamwagnon8102]

That was a great breakdown and reassembly of my saw. Thanks. I had done a bunch of those items, but the spark arrestor is where I'm going next! I'll bet that's it.

[@scottwinsor639]

Yep, Good plan. I took my saw in to a Stihl authorized service center not long after I got my first 192. I was going to drop it off and return but it was about a 30 minute drive. The mechanic came out and had me wait. He took off the spark arrestor and the screen was plugged. He just through it in the trash and said I didn't need it anyway. The saw started and ran just fine. I wish I had kept the spark arrestor though since they are required when cutting wood in a US forrest.

[@rbarrett8441]

Thanks! That did the trick for me too🤘 Never would have guessed

[@quike387]

Thank you for the video now I have an idea of what’s wrong with mine 👍👍

Excellent teardown and diagnosis. Your channel deserves more views.

This guy makes it look so easy

[@theFugitive108]

Nice work! Amazing how many people make comments and suggestions on what the problem is...and didnt even watch the video when you solved it.

[@typedbyben]

That was a thorough exam. Thanks for posting

Thanks for watching!

@@MarleyJaxGarage Intereasting video i enjoyed it. But never start a saw with the chain brake off.

[@MarleyJaxGarage]

@@joannaknowles8789 I agree when I remember. I own antique saws that don’t even have a chain brake so I just try to be aware and cautious at all times and not rely on it.

[@Skyview33]

I just watched your video and then my soul started working. But I think I still have the same problem that you had Spork adjuster in the muffler. Thank you.

[@liljrock81]

I was thinking spark arrester before you even pulled the plug. Would have taken less than a min to check.

[@motomikebuilder]

What kind of oil would do that? I have the same saw, just serviced it today. My drive sprocket has quite a groove in the center from heavy use. My sparky had some tan carbon but no oil. My clutch bearing was squealing and some grease should fix that. You make it look easy, it's a task for the patient.

[@johnmaynard8884]

I had a 170 given to me and I cleaned the screen and the saw works great.

[@michaelhuskey3225]

Thank you for great video. Job well done.

Saved me from the shop. Thank you!

[@MarleyJaxGarage]

Glad I could help out

[@paulwhelan4130]

I've got a clone version of this saw, in the manual it says to decoke the exhaust port at 100 hours from new then every 150 hours after that. I would imagine that you would normally clean the spark arrestor as part of the maintenance while you've got the exhaust off anyway. well diagnosed.

[@brianolle4292]

How do they suggest cleaning the exhaust port? I have this saw. Cleaning the spark arrester helped a little, but still seems to bog down.

[@evanwindom3265]

After watching a couple of other videos, I was suspecting the spark arrestor, and I think the YT creator probably was, too. The video could have been shorter based on that, but saving that for last did give an excuse to show folks how to walk through all kinds of other things to inspect, clean, and rule out as causes.

[@benm2081]

Dang mines doing the same thing but my spark arrester screen is fine 😔

[@danielbelleville422]

@benm2081 Did u ever figure out the problem?

[@squirrelcovers6340]

Back out the high idle screw a turn or two. It fixed mine.

[@benjobello]

Great video man!! Thank you!!

[@bcooley]

My spark arrestor wasn't jammed like that, but the whole inside of the muffler was coated in fluid. I took it off and the saw ran great. Maybe fluid has the same effect?

[@stephensticht]

NICE JOB!!!

I'm trying this tomorrow ! can't get my sthil 023 to go full throttle ...

Just wondering why you didn't back out the high idle screw.

Hello, how can I clean my air filter like you?

I used an air compressor to blow it out.

[@philliphall5198]

Those tinny spark plug can make it run crappy but I’m guessing it’s the carb metering diaphragm or pump

[@MarleyJaxGarage]

It was the spark arrestor on the exhaust.

adjust your carb simple and easy

[@MarleyJaxGarage]

The carb wasn’t the issue, proper diagnosis is critical when working on engines.

Dude check your fuel filter

[@MarleyJaxGarage]

Fuel filter was good

[@cammatney6388]

I bet it’s the fuel filter before you even say it

[@tznutz4824]

You have to set your Highs and Lows on the carb. If anyone is wondering its on the other side where your choke lever is at, 3 hole H, L, FA. Only adjust the H and L.

[@MarleyJaxGarage]

The carb was perfectly tuned. I would not suggest anyone mess with the carb screws unless needed. This is a saw that gradually started running worse over time, no indication of needing an adjustment. If anything I would recommend cleaning the carb first. Too many people start making adjustments before figuring out what caused the change in tune which in this case was the exhaust screen.

[@freezemyheaddotcom]

If you aren't using your saw in a forest in dry conditions, just remove the spark arrestor. I've personally never seen a chainsaw muffler throw a spark and it's the first thing I ever modify on a saw.
