My mower was having a similar issue and your video helped take the fear out of the task. I appreciate you posting this and passing on your expertise. Take care!
I also recommend you use a fine drill bit for the main jet. The jet is a very fine hole that tends to get clogged. Cleaning this will resolve many poor running engine, warm start issues. I’ve done mine twice in the past 4 years.
I'm working on mine, hopefully u cover it all. I just had problem with the black jet. Otherwise everything else is ok. Good video, right to point instead of bullshit. Good job.😊
I was messing with the same engine on a pressure washer and the bowl was stuck open after I worked on it. I’ll have to give it a tap to see if that will help unstick it 👍🏼
So, a few decades of acid and breake clean on your skin would come to a very ...sad....end. As you said in other videos, "wear gloves" . Cancer is a bitch. Thanks for the great insight on carb rebuilding.
Great video, I just tore this same carb apart but it's not starting. The only thing I didn't do is fully remove the idler screw and jet to clean. It could be the gas, I'm going to try cleaning the idler jet and add new gas tonight. That said, I'm confused about your comment that the lawn mower doesn't idle, that it runs full bore and that you only need to screw in the idler screw. I'm confused because I did notice that when I adjusted the screw, it did make a difference on how wide the butterfly valve would open. Can you explain? Thanks a bunch.
I think his point was that since a push mower doesn't idle for very long, there's not much reason to fuss with the adjustment. You could adjust the idle properly if you like, but you can also just max it out and forget about it.
Nice video. I.have the very similar model carb on my lawnboy that has a small vacuum diaphragm.device also.attached to where the autochoke link connects. What the heck is that part doing?? Lawnboy over complicated these units. Just give me a manual choke and let me cut grass vs fixing shit all the time 😅
@@smallengineguys that is the autochoke off the muffler linkage. I get that. But on this model there is also a vacuum based diaphragm on the carb ALSO connected to the choke butterfly linkage. The little black oblong unit that mounts on the carb towards the rear of the mower.
You didn't take out the main nozzle that's below the main jet that you made the special ground down screw driver for. That's what needs to be taken out, inspected and cleaned thoroughly.

Glad it helped
After 15 years my Lawnboy is somewhat hard to start. I'm confident this video will help me bring it back to normal (the way it used to start and run).
Thanks alot! Did this field strip in the drive way, 15 mins and she was purring like a kitten! Well done instructional 👍
Thank you for the video. My mower runs better than ever now. Very easy to follow along.
Nice delivery style. Don't have to listen to a bunch of ums and huhs, like so many other video people. To the point and done.
I appreciate that!
Awesome instruction. Thanks so much! Lawnboy feels strong as an ox again
Glad to help

Thanks! Repaired my first lawnmower
I realize this is an older video, do you have a new link to share the acid to use?

I'll die a ripe old age of 80 from heart failure.
Thanks! Very helpful!
Glad it was helpful!
@@smallengineguyswhat acid is that ?
You forgot the other half of the bottom jet. A light tap on counter it drops right out
the orifice tube doesn't always fall right out. also ran great. always do
@@smallengineguys came out for me. Couldn't imagine doing this professionally and not getting it out and cleaning

Great job. Stihl weed eater fs55 not sure which one of the # to adjust the H speed rpm.
Good video Good year
Happy new year
Thank you

What was the acid you used?
I’m assuming it was Muriatic acid.
Thank-you.

@@smallengineguyslink doesn't work?
Amazon doesn't offer the acid, so would it be sulfuric or hydrochloride acid??
I used to always wipe stuff off on my pants.
Then the wife wouldn’t let me in the house anymore.
So, I had to start using old rags.
How uncivilized…

its heat activated. it shuts off the choke when the mower is hot so if you shut it off it doesnt choke upon startup again.

You can’t see when you’re hooking it back up :(
Well done !! nice video !! do you know the part number of the autochoke kit ? Regards!

@Spwilson18 did the mower turn back on!
