This is the all elusive specific problem so many of us have with these purge bulb not filling up entirely. Great video content, bad focus sadly as this is a gem of a tutorial!
Hi Kevin your video is very important, lots of people are putting Needles into the holes where the rubber is and piercing it your video explains very well but you cannot see the small piece of rubber very well please try and make a another video in focus this will help lots of people
Ha ha .. You are a comedian. I believe I say on there, be careful not to pierce the rubber but if a "lot of people are piercing the rubber with needles" then their IQ is probably not high enough to attempt the job in the first place. I haven't got time to make another video but now you know what to do, you can have a go. Thanks for the comment though. Very entertaining.
I signed on purposely to comment, that I appreciate you making this video and sharing the information you did!! This solved the exact issue I was having with my machine. Could the video have been better recorded, sure. However, the information provided, which is what is most important, is clearly presented and helped complete my repair. Thank you again so much!!
Hey Kev, First of all I’d like to thank you for this video. The information here helped me to fix my blower. I originally changed the carb and after doing so notices the primer bulb wasn’t filling. Changed the bulb before this video and no luck, same thing. This time I took the bulb off of the old carb and the piece underneath it you showed also. Now it starts first pull. NOTE - worth mentioning is to depressurize the gas tank before removing the piece that holds the flow and return lines, makes it also safer and easier. Thanks Again Jim
Hi Kevin, one more very appreciative viewer here. I dunked the primer assy in an ultra-sound cleaner and the tiny bits came out. Thought it was a lost cause until I learned the order. Thanks for your “messing about!”
Greetings from 🇨🇦. Thanks for taking the time to show how to do this fix. There's not a lot out there on how to fix the primer bulb issue. I've got the same thing happening on a Stihl FS38 string trimmer.
Thank you. Tearing mine down today. Sometimes when I spray the carb down with Brake parts cleaner it starts working again. Going to do some major surgery. Lol. Cheers.
Excellent video and explanation. I have a Husqvarna blower with the same problem. Thanks for sharing, judging by the comments you’ve helped a lot of people with a similar problem.
By Jove, (I believe you folks use that phrase) I think you've got it....I mean...I believe this could be the issue with my less than 3 year old stihl. The rubber bubble seems to be intact, so it had to be a internal problem. Before heading down to the repair shop, I searched on utube & your video was listed. I'll follow you steps to check that tiny spring. Will update this comment after the tear down. Big thanks from the Colonies.
Mr. Peters, your video is nothing short of a miracle! Just by me watching it, the blower decided that he (or perhaps she) might as well stop acting sick. Putting the blower on my workbench, I thought I better try it once before tear down. After pushing the bubble a few times, it seemed to firm up like it's meant too. Previously, it stayed soft & felt like I was only moving air. Sure enough, it started right up. I really do appreciate you making the video, as I just may need it for real in the future.
@@billfrank6505 Well, thats a jolly good show old chap. i'm not sure which one of the colonies you inhabit but with a name like Bill i suspect it might be Australia? i failed to mention in my high quality video but fortunately you seem to have realised that these machines do actually have feelings and if you treat them with respect instead of F..ing and B..ing them they will return your good will. You did absolutely the right thing to give it another chance before pulling her/him/it to pieces and i believe that you will get many more months of service before she expires again. Best wishes from Blighty.
Thank you for the video. It was exactly what I needed as the problem was exactly as you said. I searched my counter and floor for an hour for the little black valve piece only to find it was stuck in the middle of the spring. Just to help everyone, pushing the bulb pushes air or gas out the outlet tube. The check valve allows a vacuum in the bubble. This opens check valve on bubble base to draw air out of carburetor which subsequently draws fuel from tank into carbutator. With every push of the bulb, the vacuum is restored and the cycle continues to draw more gas through carburetor and air out the outlet. So any leak in any carb channel or sticking valve will stop the whole process. so issue could be at any point from fuel filter all the way to the check valve you has trouble with. Before starting, it's best to soak the carburetor and bulb base in mixed gas for a day if the carburetor has been sitting empty.
After being interrupted whilst taking this apart, I also managed to lose the little black valve piece. Ended up cutting a new one out of an old diaphragm and so far it has worked a treat.
Thanks for sharing Kevin! I have a (nearly) new BG50 and see the still very clear bulb is not pulling fuel into the carb. Shot some carb cleaner in and the blower started for a few seconds. Must be sucking air in like you describe. I'll attempt to free up the valve using a dull but pointy scribe and hope to solve the issue. Thanks again! Didn't notice a focus issue much...my glasses need to be updated though...
He made a very , very , Good presentation , to take apart a working with nothing wrong with it is good hearted man , taking his time to break it all down is really, and got to be really a good hearted man , showing all details , he's better than many , some people don't have the time , heart , patience to detail everything, they show you beginning a few screws a the ending , Great Job on this video , keep up the good works , :
Thank you Kevin. I removed the bulb assembly soaked it in gasoline and flushed the unit by pushing the bulb and letting the gas flow clearing out any clogs
I was so happy to find this. What a great tip. It ultimately didn't work for me but maybe the next one. Regardless, it never would have occurred to me you could remove those pieces. Thank you for posting this. To be clear, I'm not being facetious.
Wow what an amazing video you saved me a lot of frustration! Thank you for taking the time to make the video and help all of us. You did such an amazing job explain how to repair the blower. Have a wonderful day.
I just put a purge ball on mine used a long Thin screwdriver To take the Purge ball off After I removed the casing. I put a new purge ball back on. Put everything back together. Pumped the ball no fuel. I should have checked out your video Beforehand!😅
Thanks, Kevin, very helpful description of the problem and solution. Difficult to view, seems you have great camera and lighting, but the closeups were all so out of focus it hurt my eyes to watch, but the audio was good and helpful commentary made up for the camera person not trying to focus the closeups. Cheers.
Thanks Top C. Yes, my wife said i should do it again with a proper camera but I think my film career is done. Hopefully you fixed your blower. I appreciate the comments though. Check out "trouble in Old Dilton" for more clarity and entertainment. Much more professionally done. !
Mate that was awesome and fixed my problem. Where did you learn about this? No other video talks about this issue and by the comments it is common. Thanks again.
Thanks Heath for your lovely comment. I was just a little hacked off after going to numerous garden machinery service places and nobody knew how to fix them. Their only solution was to buy a new base which was about £27. I always figure that if you've got to buy a new part, then you have nothing to lose by smashing up the old part. It's nice to help others and thanks again for your comment.
I have worked on many 2 strokes small engines from Chainsaws, weed wackers and RC has cars, I never knew this. Thanks Kevin. Going to give this a crack. Cheers.
All stihl equipment is having this exact issue. This is how every single one of my pieces of equipment breaks and all they want to do is charge $125 for new carb and then it does it again. I miss my old stihl stuff
Hey Kevin. Thanks so much for the video. Do you know what the little rubber thing is called that you mentioned only an idiot (me) would push a pin through when removing? I have a couple of carbs that I've done this to and think that might be the issue why they won't fill the primer bulb with fuel. Thanks again
They are just bits of rubber which i think you would be unlikely to be able to buy. you would probably have to buy the whole bubble box. Take it out on a white cloth and close to the table and it shouldn't go anywhere. It would be pretty difficult to put a pin through. You'll be fine.
The bulb actually sucks fuel through the carb, into the bulb, then it exits the carb and returns to the tank. The bulb doesn’t “push” fuel through the carb. Excellent video though!
Ive a bg86 thats doin this. I left it sittin all winter and now it wont hardly start. When i can get it to start it wont stay runnin. I probably need to disassemble the whole carburetor and clean it real good.
Just fixed mine. That was the problem. But BK86C...could not get that little part out so shot it with compressed air from small can I use for electronic repair down into that tiny hole..out sprayed the fuel...Problem solved! BUT, getting that BG86C handle back together was a real pain....ouch...but learn something along the way....Thank you
Wow, I've never seen anyone take apart check valves. Zama recommends soaking the primer body in gas, petrol for you :-) . And never use compressed air, strong solvents, or ultrasonic cleaners to clean Zama carbs. Even the carb body has those tiny check valves in it. Cheers.
