I had been avoiding your videos as I recently lost my workspace, but like an STD I knew I had to be exposed sooner or later. You do good work friend, and from me that's enough, thanks.
Great video I have never needed to replace a seal on one for my four mixes yet but If I do now I know how to. You have a link for the stihl flywheel puller?
Great job Jeremy! I also love making tools, very satisfying and saving money is awesome. Ingenuity is the name of the game, sweet press for the crank seals. Merry Christmas and a Happy New Year to you and family.
Will you do a pressure/vacuum test video on the stihl 4mix? I don't see any for the 4 mix on you tube. Thanks and love all your vids. Have helped me out alot.
I really appreciate all of your video's especially this one. I have a Stihl fs130 it takes about 3 mins to heat up and then it runs with power but the rpms are radical engaging the throttle. With this video I'm going to trouble shoot it for one last time thanks again
Subscribed a few videos back because you are amazing. In the time your video is finished, I may have been able to get out 3 screws :-) You save people lots of money with your talent. You may have shown this in another video, I'm wondering is there a chemical spray that will clean off that grime build up from mowing and triming without penetrating the motor? It would seem the cleaner you can keep the motor the cooler it will run saving some wear and tear in the long run. Your camera angle is great too.
Nice video for finding vacuum leaks. My issue with a BG65 blower I recently acquired, is this. I can get it to start, but as soon as you take the choke off, it'll stall right out. I've found if I start throttling it up while I take the choke off, I can get it up to full throttle and it'll stay there. If you feather the throttle within half to full speed, it'll respond ok. But letting it idle down to less than that results in a stall. Took the low speed screw out, cleaned out the port and screw. Reinstalled and set it to one turn out. Rechecked, but still responds the same. I noticed if I kept backing the screw out to about 2-3 full turns, it would take longer to idle down, but still stall. So I tried spraying carb cleaner around the carb (closest to the intake flange)while I was holding the throttle. And noticed it would run longer, and sometimes stay running, when I let go of the throttle. So I assume it's got a vacuum leak. Was getting darker and colder outside, so I quit for the day. Just wondering if the engines in the BG65 are similar to the trimmer you have. So I can check for leaks from the same areas.
I have that same trimmer, on a cold start, full choke it sounds louder, which is not normal, then half choke very high rpms and the trimmer head is spinning like crazy which also is not normal. Then when I take it off choke low rpms, then after adjusting the idle mixture screws to the correct rpms (3000), then pulling the trigger to reving it up it revs up perfect but after releasing the trigger it idles high around 4000rpms then the rpms will slowly decrease then it will shut off. I have replaced it with two carburetors, new fuel filter and fuel line hoses and a new spark plug. What would you suggest I try next?
Love this guy haha "Finish sending the seal home" guy reminds me of Adam Sandler from HAPPY GIMORE "just tap it in tap it in" 😂😊 hey Jeremy where can I buy one of those rear seal pullers?
MowerMedic will this work on a lawnmower, got a customer that brought me a lawnmower that running wide open and the customer said he thought it was the crankcase seal due to the lawnmower hit something hard
A lawn mower usually has a governor which controls the speed of the engine, if it is running wide open after a hit you should start by resetting the governor in case ot slipped due to the hit and also verify the throttle linkage is not binding
Thanks for this video. I have a stihl FS100RX that wont stay at idle. I can adjust the carb and it will idle, then rpms come up and wont maintain a steady idle. I suspect I have a seal leak, and now I know an easy way to check/repair it. Do you have a link where I can get the seals? I didnt see them when doing a quick search on amazon.
Hey bro I have one question for you what do you call the part on cylinder heads that's located on top of the valves they look like little caps it sits on top of the valve stem underneath the rocker arm to adjust because I need to get that part for my cylinder heads on my riding mower I just need to know the name of that part please hit me back
Haven’t watched the video yet, but Jeremy do you have any kind of handle on when seals generally wear out? Operating hours or maybe age of the machine or any other parameters?
Main bearings goin bad can cause seals to go out too, replacing the seals would just be throwing money at it, try to wiggle the starter cup and see if you have up and down/ in and out play if you do it needs bearings,a tip for you do it yourselfers.
Good morning. Great job as always. Just quick question. Did you need to remove the cam cover plate? I assume you were making sure the seal on it was not the source of the leak.
Mower medic you should make those screwdrivers and sell them on your online store so I and others can buy one and know it's right instead of making it myself if you do make a video on them so I know too go buy one
I like to watch a master craftsman at work.
It’s funny how many of us have a draw full of little washers, spacers and special home maded tools 😊
And we remember them 😮
Perfect camera angles for this vid.
Man u got your stuff together on these weedeater
Jeremy,,,,putting out good 4 strokes videos,,,,,Hes the best on youtube showing stuff like this,,,,,Thanks
Thx you've just shown me the best, simple and easiest way to test a 2 stroke for leaks
I had been avoiding your videos as I recently lost my workspace, but like an STD I knew I had to be exposed sooner or later. You do good work friend, and from me that's enough, thanks.
We learning everyday something new from you Jeremy 😉👍 Thank you!!
Great show man
Thank you for showing us your technique. The sound distorts really badly when the engines are running though. I love the sound of a 2 cycle.
GREAT VIDEO BROTHER. Learned a lot
Great video I have never needed to replace a seal on one for my four mixes yet but If I do now I know how to. You have a link for the stihl flywheel puller?
Gosh, is there any substitute for experience and ingenuity! Thank your Jeremy.
You are very professional!! Thank you so much for your knowledge!! Love it !! Keep yourself safe !!👍🏻👍🏻👍🏻
Thanks Jeremy , I have some real old STIHL equipment with no problems - nice to know the how too process . will save this video ...

Love the flywheel puller # please 🙏
If I get a low reading on my string trimmer how would I diagnose the problem? For example, how would I go about finding the problem?
Great video! Where did you get that awesome flywheel puller? How can we get one? Thanks for all your great content!

Great little tool you made there but was there a reason why you didn't use thread lock on cam plate screws?
Screw heads are serrated. No thread lock from factory. Not needed
Im checking my stihl blower tomorrow... Do u have a video on that screw driver you were using
i never new how to do it. thanks
Where can I get a flywheel puller like that? Thanks
Great video learn a lot that’s the way to do it😊
Very good MM !

@@imanolberecibar thank you I’m just out of Small Engine Repair Class and very new at this
Excellent video it helped a lot thanks👍
Where to buy that puller
Thank you
Just replace both if one leaks because of age 😊
Silicone is great stuff if you follow the instructions and properly install part and then tighten 😊
Thanks for this video. I have a stihl FS100RX that wont stay at idle. I can adjust the carb and it will idle, then rpms come up and wont maintain a steady idle. I suspect I have a seal leak, and now I know an easy way to check/repair it. Do you have a link where I can get the seals? I didnt see them when doing a quick search on amazon.
Looks like there was a piece of silicone that fell into the crankcase and was not cleaned out. And the seal was installed trapping it inside.
Could be, I’ve seen sealant get between spark plug electrodes from factory
To check the seal
You need to patent that screwdriver design before someone one else thinks of it L.O.L great video
Great video. Thanks
Fascinating.
Great video once again. What is a ballpark price for repairs and are those seals pretty much standard for all stihl equipment
Thank you
Where did you get the flywheel puller
Guy you did a good one today ,make one tool for me,i will pass by one day
Hey bro I have one question for you what do you call the part on cylinder heads that's located on top of the valves they look like little caps it sits on top of the valve stem underneath the rocker arm to adjust because I need to get that part for my cylinder heads on my riding mower I just need to know the name of that part please hit me back
Awesome my friend 😁
If these seals are leaking that means can the machine have severe starting problems is that true?
The meat and potatoes of crankshaft seal replacement on a strimmer!
Thank you for the help!!
Very nice video
I do that a lot. Good tip
Do what?
Great video. 🛠
This is also happening to my Stihl FS 100 but it doesn't hawe a leak i checked it i really don't understand what is the problem
Hi Jeremy what type of sealant did you use on the cover and can that same sealant be used when you seal the case halves together?
amzn.to/477e68E
Great tip
Wow you just manhandle those 2/counterfeit 4 strokes . They just give up and runnnnn!
Nice tool
Haven’t watched the video yet, but Jeremy do you have any kind of handle on when seals generally wear out? Operating hours or maybe age of the machine or any other parameters?
There no predetermined time for when
Seals go
Out
@@THEMOWERMEDIC1 SAS! Qqqqq
Main bearings goin bad can cause seals to go out too, replacing the seals would just be throwing money at it, try to wiggle the starter cup and see if you have up and down/ in and out play if you do it needs bearings,a tip for you do it yourselfers.
Bearings are fine. Seals failed due to overheating and crystallized the rubber lip
impressive
Good morning. Great job as always. Just quick question. Did you need to remove the cam cover plate? I assume you were making sure the seal on it was not the source of the leak.
Top advice .
how cool is that you should pattern that tool lol
Thanks👍
This guy is real
Good job bud
Awesome
Mower medic you should make those screwdrivers and sell them on your online store so I and others can buy one and know it's right instead of making it myself if you do make a video on them so I know too go buy one
Straight to the meat and potatoes 😂
You should clean the spark arrestor is almost completely clogged
Negative. It’s 100% clean
I need to check my chainsaw like that
GREAT TUTORIAL!! Expertise is so invigorating to observe. Thanks Sir. BTW, where did you get that crankshaft seal puller and installer??
I made them
My auto shop used propane to locate my intake leak. I found out the wd40 works great.
Wd40 like the new formula of it? That doesn't combust.
Could be ok for vacuum leaks tho, never tried it.
Hi mate I change both crank seals on my equipment as you know Sod’s law will come and bite my ass if I didn’t the other eventually will leak
Take the spark arrester screen off while your at it !
And cause a forest fire? No thanks
The hack
Disgraceful... you need to clean up that grime/oil/grease before removing those seals... bad practice.
Hello Jeremy!Do you know does stihl have a specific tool for pressing rubber seals?
Awesome
