An amazing classroom today, you are my new small engine instructor i can count on for in depth knoledge of step by step instructions. thank you for the class.

[@austinado16]

Wow David! Thank you so much. I really appreciate the complement and the feedback!

And that is the way instructional videos should be! Good information, showed and told what to watch out for, knew the names of the parts and pieces and what they did. Told what you used for lubes and seals. Anti sieze on the plug threads is a good idea. Easy air gap setting. Good info on bar and chain mounting and adjustment. The spark arrestor screen are almost always plugged but obviously wasn't the issue here. Great job.

Wow Scott, thanks! You made my day!

best rebuild video iv ever seen on youtube. although is it out of line that it erked me that he didn't clean the grime off the inside of the engine casing and everything else while it was apart. my ocd.

Thanks for the comment. There have been a few people commenting; upset that I didn't "detail it." I've spoken to this in a subsequent video, but I'll mention it here: This is production work, not restoration work. Nearly all of the equipment in my videos is going right back into (usually) 3rd party hands, who don't care about how they use the equipment, or where; or what condition it's in. It's not theirs, and they are rewarded with a brand new machine(s), as soon as they destroy the current machine(s) or the truck they are given to drive around in. A few of the old-school Shindaiwa machines shown, have been for myself, typically not shown in the videos, those get a bunch of new plastics, decals, hand grips, and other stuff to return them to as-sold. I take care of them when I use them, which is sparingly. So yes, if it's for me, it gets dialed in, right down to the decals, and it's kept nearly like new.

Awesome and thank you. I believe this is my problem.

You're welcome!

Thank you for the video. Definitely helped me with working on my MS194T. Seeing how things came apart and what to watch out for on reassembly is the best.

[@austinado16]

You are welcome! I'm glad it was helpful, and thanks for the nice comment!

My ms462 clutch bearing broke, and I've since repaired it. However the saw is running lean now. Piston isn't scored (yet), carb been cleaned out -- could be the seal between the crank and piston letting in air....thanks for the video!

[@austinado16]

I hope you're able to get it running correctly. Thanks for watching.

Great video, I’m having an issue trying to pull the carb switch off? Any suggestions?

[@austinado16]

By "carb switch" are your referring to the orange choke knob? If so, pry with a pair of needle nose pliers, or similar, at the base of the orange switch shaft, and sort of against the carburetor, until the orange shaft starts to move, then you'll be able to make further progress and it'll finally slide up and off. They're shoved on very tightly.

[@WrightsOrganic]

@@austinado16 yes! Sorry the choke knob, I finally got it off was a pain in the butt. Thanks for the response.

[@austinado16]

@@WrightsOrganic I'm glad you got it. Before you reinstall it, look up inside it, and line up the flat side with the flat side of the metal shaft that sticks out of the carburetor. Otherwise it might break when you try to shove it back down and get it to "click" into place.
