Watch this video on how I made this pressure tester with parts I had in my shop: th-cam.com/video/HbSbugUHTxA/w-d-xo.html
I was going to ask how you made it and how to set it up. Thanks lady you rock
I'm not kiddin' here - Stella you should teach shop. Fantastic as always. 👍👍👍
Thank you Mr Claus! Classes would be too long, I probably rattle on too much for that. Cheers!
@@TheLawnmowerLady outstanding breakdown
I have been watching your videos all morning.
I have learned quite a bit from your videos. I am a mechanic by trade but my small engine skills were lacking.... that is the reason I decided to check out your videos.
I'm sold, your knowledge is awsome.
Thank you Mr J ! I appreciate you watching. Cheers!
Always a joy seeing you work. thank you
So nice of you. Cheers!
A bad fuel mix and a plugged carb filter huh! Some people think that the more oil the better. Great video Lady!
You’re right Mr Bill ! Very common misconception. Thanks for watching. Cheers!
Another good example of explanation of repairing and diagnostic of this husqvarna 128cd
Thanks Mr John! 👍
Hey Stella! I just found your channel after watching you on Micks live video yesterday. What an awesome channel you have, excellent video quality, audio quality, camera angles and way of conveying your content. Really enjoyed it all, thanks for sharing - I’ve just subscribed! Regards, Tom from Australia.
G’day Mr Tom, your kind words are most appreciated. Thank you for watching. Cheers!
Wow Stella! Very nicely done young lady! Please keep these videos coming for us. I hope all is well in your neck of the woods.
Thank you Sgt, I will. Cheers!
Hello Stella, it is good to see your hands at work, it is definitely summertime!
Thanks Mr Joe! I appreciate you watching. Cheers!
Another great video Stella
Thank you 🤗
I love your homemade pressure tester!
Thank you! Cheers! One of my very early videos is how I made it. I appreciate you watching.
Awesome content Stella, I like those small Husqvarna engines. Loving the pressure tester 👍🏼
Thank you Mr James! Cheers!
I love your videos!! At first I thought you were just another woman for show working on mowers. I soon realized that man she knows what she is talking about!!! I love it!! Your videos are awesome and very thorough! Thank you! Watching from Falkville Al.
Thanks Mr Chris 👍 I appreciate you watching. Cheers!
Thank you for this video…I don’t do a lot of 2 stroke. My repair was unsuccessful for what I think is the diaphragm being a little too hard. I ended up ordering a new aftermarket carb for cost reasons. I’m contemplating on just robbing the gaskets from the aftermarket carb
As long as the holes line up, and the little peg sticking out is the same size, it should work. Thanks fir watching. Cheers!
Yay finally a channel pops up on my feed with someone playing around with small engines. I love me some small engines
I appreciate you watching. Cheers!
Well, I’ll be watching this video a few times. I just got comfortable with taking apart m Honda carburetor. Looks like I have another kind of carb to learn….Thanks for another great video……
You got this Ms Inisfad ! Thanks for watching. Cheers!
ms LLL - thank you for posting. i'm impressed by your visual acuity & steady hands, working w/ such tiny parts. i'll add 'furry booger' to my technical vocabulary. take care - dLL
LOL!
I really enjoy your channel! Thank you so much!
You are so welcome Mr Michael ! Thanks for watching. Cheers!
Well done. Love the pressure tester.
Thank you! Cheers!
I had a 2 stroke scooter with a small engine like the ones used on weed whackers when I was younger. It always rattled horribly and the smoke was so thick and white that you could tell I rode past your home for a good 30 seconds. It would also stall easily after cold starting. I rode that thing for so many years and honestly I did not even know anything was wrong. I thought that is normal for these engines until I saw this video! I don't have the scooter anymore because the pull start broke on me and given its age and rarity, there was no finding a replacement
It probably needed a little TLC. Thanks for watching. Cheers!
Nice job Stella!!
Thanks Mr Bob! Cheers!
Nicely done as usual!! Great filming and explanation on the carb dissection. Your attention to detail is most appreciated. Your patience is also a plus. Glad you continue to make top quality demo videos with your welcoming demeanor. Thank you and stay well!! 😁 How did you ever get started in small en gine repair??? Just curious... Happy trails!!
Thank you very much Mr G! Antique scooters were my doom :)
Just sat with a coffee.. so why not watch my favourite lady.. good job.. yeah maybe the fuel or tune..
Cheers Mick! I appreciate that. Happy Easter.
very nice work
Thanks for the visit Mr IHG!
Big up from Scotland 👍👍👍
Thanks!
Love it videos and u really know what it doing I have 2 echo one pas 225 and a curve gt225 both are 2 years old still going tho own a small business of mowing and weed eating and work a full-time job
Thanks for watching! Those Echos are pretty rugged when taken care of. Cheers!
Great job stella Nice one lovie
Thanks Mr Edward ! Cheers!
Nice job and video Ms Mower Lady, hey I know a guy over in Denmark named Claus, he's some sorta of oil guru and knows so much about B&S engines. 🙂🙂
I've heard of that guy I think? Real stickler for OEM parts, I hear 😬
Yes, you definitely know this fella then. 🤣
Nice fix Stella and than you fro the comment on Hoby motor channel x
Happy to help Mr Gary. Cheers!
Thank you. Good stuff!
Thanks for watching Mr Bill ! Cheers!
!awesome sauce
Excellent video. Thanks. MH
Glad it was helpful!
Nice job, thanks for the vid, 👍👍
Thanks Mr Tony! I appreciate you watching!
Nice video and nice vacuum pump you are the gal
Thank you Mr Hank! Cheers! 😘
I have two of those exact same weed eaters. Had em for over 6 years now never had a problem with them. Husqvarna is my favorite and go to brand. They've been reliable to me. The Smoke could be to much oil in the fuel or it is running rich. Pump diaphragm could also be the problem.
You can almost always substitute Poulan parts for these models. I actually have a video coming soon about that. Thanks for watching. Cheers!
Wow nice job.
Thank you! Cheers!
@@TheLawnmowerLady absolutely, and love the RPM reader!
Your definitely not Claus, I could understand every word! 😁😁 I do like a good carb rebuilding video, thank you Stella
🤣 Thanks Mr Al. Cheers!
Beautiful work my lady 👏👏 , I really need to make one of those pressure pump tester using things here in the uk ( but I have no clue how to ) I just can’t find the same material on your tutorial 🤷♂️🤦♂️🏴
Thanks so much 😊 The other video has some AMZN links, not sure how those work for you in the UK. Cheers!
@@TheLawnmowerLady oh thank you I will give them a try , I have an old fs55 stihl trimmer in need of this kit as when I remove the fuel cap ( although it has been bought brand new from a trusted source) I just need to verify, much appreciated my lady 🙏
Thanks
Wow! And a SUPER thanks to you for supporting my channel. Cheers!
Hi Klaus! That's just like mine! Might I be the friend? :-) Thanks for the video!
It should look familiar!
Just want to tell you thanks for saving my honda mower. Now its the new to me Husqvarna weed eater purchased like 5 yrs ago at lowes, don't know the model, but the one that takes the attachments. Anyways, I just changed filer and plug last year. as always starts up beautifully but takes longer and longer for engine to warm up and get out of half choke to full run otherwise it dies out on me. Now I had to run it for say like 12 mins in 1/2 choke as otherwise dies out on me. As time went on, I could move the handle further toward full run but If I went to far would just die. Think I switched the inlet and outlet fuel lines, something else, maybe carb needs a cleaning? Think I can get away with just a fuel additive cleaner?
Happy to help. Probably need to clean out the fuel inlet screen on that carb, new fuel filter as well, and check the spark arrestor screen is not clogged. Thanks for watching. Many of the videos in this playlist show how to clean that style of carb: th-cam.com/play/PLscwXOlCLzlxo_dEcDTBgzz_2l1Hw-N6u.html Cheers!
Good video miss Stella I don't like 2 strokes give me a 4 stroke engine's all day long 👍
I hear ya Mr Mark! I enjoy the challenge of working on them. I don't like they take up space in my small shop waiting for parts. I have a lot of the common parts, air filters, carb gaskets, etc for lawnmowers, but there just are so, so many parts that just only fit a single 2-stroke machine or another. Cheers!
Love your channel. I have a Stihl ms 194t less than a year old. Only wants to run on choke. Any thoughts?
Definitely sounds like a fuel delivery issue. Either the tank fuel filter is clogged or the tiny fuel inlet screen inside the carburetor might be clogged. I don’t suspect a bad tank vent. Those carbs are very similar, so the same procedure I showed in this video. Thanks for watching. Cheers!
Nice work! My weed eater was smoking (white) very bad so I replaced the car heater and new spark plug even cleaned the nasty muffler and started it up no smoke but within few min it started smoking. I am clueless! It’s a 4cycle. Any idea?
White smoke is usually oil burning. double check your oil reservoir is not overfilled.
If I were the guessing type(which I am) I would guess a combination of the wrong plug and also running rich. A hot plug can hide a rich condition on a 2 stroke and that particular motor is REALLY picky about the plug it uses, barely runs at all without a resistor plug.(ps. I love that external tach, you have all the cool tools!)
Embarrassed to say, I'm not ever sure if I checked if it was the correct plug. (It probably was the original) Thanks for watching Mr Bill. Cheers!
@@TheLawnmowerLady I always check the plug, but you know why... one got me😒. I got that exact motor with the wrong plug and after staring at it for an hour I tried the plug, and it started right up. I was surprised so I looked it up and the one in it was the wrong one(wasn't a resistor plug).
@@GuysPlayingWithTools That's actually my weed eater she's working on in the video. :-) It is the original plug. And the lines, though they looked like they were replaced are also original. Very few hours on that thing.
@@81bajaj you picked a nice weedeater and an even nicer person to work on it. 👍
@@GuysPlayingWithTools Yeah, Star is great! We go way back--in the same vintage scooter club!
@The Lawnmower Lady - was wondering if you could help me . I have the same machine, but when u put the choke lever the whole way back, the machine turns off and when the choke lever is in the second position, it will run and the head will spin continuously. I can’t start it on no choke (full way back) any ideas ? I’d appreciate it thanks.
If you have to rely on partial choke to keep it running, you have some fuel delivery issue. Need to fix that, before you can address the head turning at idle. It's starving for fuel somehow. Perhaps and air leak? Clogged fuel filter? I wish could be more helpful. Thanks for watching.
I always have Fel-Pro 3157 gasket material on hand for various projects. I probably would have cut that gasket with scissors, exacto knife, & punches rather than forking out $15 for a new one. I must admit, though, some gaskets are easy to cut but that one is a bear, probably would take a half hour. For me as basically a hobbyist that's okay. For you as a business person, maybe not.
I sometimes do that. But it's usually a matter of time, not $$: I'm a glorified hobbyist myself. I appreciate you watching. Cheers!
It’s winter time and I’m all ready cutting out gaskets for next year
PLEASE HELP. Could please let us know where to get technical and trouble shooting Data? And how to order parts. Thanks for the videos!!
You can find parts easily typing the model number and the words "parts diagram" in google or another search engine. You should get multiple hits at several parts houses. I'd call first to ensure the part is on the shelf ready to ship. Some don't list real time inventory online. Hope this helps!
Thank you so much!
Do you know what size spark plug a Huskavarna. of 128LD And what wrench size you would need?
Pretty sure it's a NGK BPMR7A which uses a 19mm spark plug socket. If you don't have one, this is Husqvarna Scrench (for chainsaws) is a handy tool as well: amzn.to/3W2UBvO
I was gonna ask about the pressure tester?
Thanks JB! I had a Miti-Vac brake bleeder kit already, bought the fuel pressure gauge at autoparts store. th-cam.com/video/HbSbugUHTxA/w-d-xo.html I appreciate you watching!
I think I would have tried the high speed needle first....then maybe the low needle......just a thought....
Good ideas. Thanks for watching!
Nice video, but you can get a new carb for this for about $20.00 with new lines and gaskets.
That's true. To be fair, the quality on some of those aftermarket kits are pretty hit and miss. Thanks for watching. Cheers!
The Hooskarvana runs like new
Thanks for watching. Cheers!
I replaced my piston and carburator, but now it won't start. What could it be?
Unfortunately, diagnosing over the internet is difficult. That said, start with the basics: spark, fuel, and air. Each of those entail other issues: air is more than a clean air filter. What is the compression? Have you checked for crank vacuum and/or pressure leaks?
Another channel @VintageEngineRepairs he does a lot more 2-stroke repairs and diagnosis. I hope you get it sorted out. Thanks for watching.
@TheLawnmowerLady thanks, I will check the compression. I don't have a tester now. Is normal to have a really loose piston ring?
@@anrivera1975 yes, but they should have a notch on each end that mates with an alignment pin in the ring groove on the piston.
Those furry boogers will get ya every time
LOL!
My nail is the best tool to remove the gasket
Works for me.
This engine, in my case an "LD", is questionable. Granted the one I have was beaten and neglected badly, but so are everyone of my other "keepers".
I'm always amazed at the abuse these thing take and keep on running.
Its supposed to smoke, its a 2 stroke
And it's supposed to not run badly...
Filter intrusive
The whole time I was thinking, “Why is Stella doing all that stuff instead of dumping all the old fuel first and running the correct mix through it until it clears up the smoking?” In the end I’m grateful you did the rest or I never would have discovered my next toy to purchase - that really nice tach! Thanks so much for all the work you put into this, especially all the details in the description. 🙏👍🔧🧰
There’s a link in the description for that tach. Sort of overkill for lawnmowers. I purchased it for motorcycles, but it’s handy all around. I appreciate you watching. Cheers!
The Lawnmower Lady Oh, I’ve already followed the link and bookmarked it! I got a remote tach a few months ago and it works just fine, but it’s kind of small and doesn’t have nearly the capabilities of yours. Being able to retain measurements as well as measuring ignition voltage are strong selling points. I was wondering if that tool could do a better job of determining fault with coils and plugs than inline spark testers. Have you used it for that at all? I work on all kinds of small engine equipment so a more capable tach would be well used.
@@Rein_Ciarfella interesting, I have not used it for that, I should next time I’m testing for spark. Sometimes it’s difficult to find a good ground that still allows me to see the tester while pulling on the starter. The proximity of how far the probe can detect is pretty large. The only thing that confused me at first was many small engine systems use a wasted spark ignition. So I have to set the tester for two cylinders instead of one. I guess I could just do the math…
The Lawnmower Lady That proximity would be very valuable, especially on things like mowers and chainsaws (where I need two hands)! Now I’m gonna have to go down another learning rabbit hole and teach myself what a wasted spark system is. 😉😂👍🔧🧰
@@Rein_Ciarfella it’s a great idea for sure. Shameless plug: when you’re ready to purchase, click my link again. I get a small commission, no cost to you, but that click is only good for 24 hrs. 🙌🏽
Sorry, Husqvarna and other competitors echoes got you beat heads down they start every single time go by yourself an echo people
My observation is with proper care, and routine maintenance, it will last a long time, regardless of the brand. Thanks for watching.
