What do you think about this video?

galantdrive: Thank you for the video ...now must I find a store for a new primer bulb for my Uniropa lawnmower with briggs and Stratton motor . Now my carburetor rubber also cracked ... it may also be that he is therefore sometimes irregular is idling ? Greetz from the Netherlands

elton eysh: what is a red primer for? what if there is no manual choke lever? what would you do to unflood the motor?? thank you!

Chris Knoell: Thank you so much for the awesome tutorial. Even I think I can do this!

JasonStriationfilms: Really appreciate the training tip. Took the small engine course and they never showed us how to do this. Thank you. 

joe a: Good video & instructions. Thanks !

Lisa G.: Thank you. Great video! Couldn't figure out how to remove this type of primer bulb. Very helpful, made life easier : )

Jeff Inselberger: would this apply to a lawboy as well?? and great vid 

Stanley Beck Jr.: TY again Bro DonyBoy you've been a big help already subscribed so two thumbs up :)

Ask the Builder: Great video. Fantastic job on the close up shots.

C Dillion: Does it matter if you use the primer with the hole or the one without the hole?

KB in MD Last: What's the difference in the primer bulb with a hole in it and one without the hole in it? 

Barry McLaughlin: Donny does a bad bulb hinder the carburetor from running? I cleaned my carb out today and used high compression air in the carb. The bulb expanded and now doesn't work. I poured a bit of gas into the carb and lawnmower started only for a brief second. Does the carb need a tight seal for the gas to flow? Thanks in advance Barry

Vincent Kelly: Thanks a lot. That's just what I was looking for. I was wondering how to remove that retaining clip.

Angelo Montante: Your the best I thought I needed a new primer and all that it was is water in the bowl. Thanks you saved me

John: hey dony I need your help. Im fixing the same mower and the bulb works and primes but will shut off after a couple seconds. I completely cleaned the carb and all the ports seem fine, but gas doesn't seem to flow through continuously. any suggestions?

johnnieb15: Thanks.. Been lookin for a video on this all day

FantasyAwakened: Holy crap finally so thats how you do it! Thankyou

jvargas454: Crying out loud.. THANK YOU!

Jeff Wall: Thanks a lot for this video

donyboy73: @mikebrady721 thanks for telling me

hardcoremofo: I am stuck with these 2 questions. 1. what happens if I prime the red bulb more than 3 times like 8-10 times? 2. Is it normal if I over-prime, that I see gas coming out of the carburetor bowl? Or that's a separate gasket issue.

vermonter247: Thank you. I didn't realize it was that easy.

spiavsspia K: Another great vid. I have told (from the shops around here) that it is too hard to replace them and just get a new cab.. However I see the truth of the matter and it is what I have thought all the time thanks Donny!!!

akaBPhife: nice. . but think finding the parts will be the challenge now

dblixt1: I have to change the primer bulb in a 4.5 HP Tecumseh on a lawn boy. I rebuilt and cleaned the carb and I still have the same symptoms, start and stall and when I did manage to keep the engine running it would stall when I installed the air cover. I did get the self propelled fixed though and that is a plus. Making headway. :) Have a good day all of you and Dony...

lourox20: thank you!!!!

العامريه للميكنه الزراعيه: i bought digetal camera for make videos (repair lawnmower) soon i hope u watch and thank u for ur videos...i Benefit from it

peter sweeney: whear can i order an carborator . if can send link to site

donyboy73: you may want to watch some of my carb repair vids

Pierre D: THX man appreciated

ncrdisabled Submarine vet: Great video I was told that Tecumseh was bankrupt and no longer made parts or small engines. I have a older mower that can not get parts for and when I went to NAPA and online stores have told me that info. Keep up the great videos!!!

donyboy73: @th19940305 i stock a lot of them

donyboy73: @th19940305 it's my home garage converted into a shop

donyboy73: @joeysways i have a parts distributor, also mowers4u dot com is a good place

ClassicTVMan1981X: My 1984 Toro TNT100 engine (made by Tecumseh) seems to have a degrading primer bulb (which may or may not be the catalyst for hard starting), and I placed an order for a new one via Jack's Small Engines. I wonder if your advice may work in the meantime?

David Quenzer: Very good video....exactly what I needed!!

jamie young: So I have changed my primer bulb but it will not prime way is causing this????

Robert Camp: donyboy 73. I have a tecumseh carb that is missing the primer bulb. Is there a easy way to tell what primer bulb Is needed. Vector(black) or non Vector (red)? Also could you explain the differences? Thanks for your help.

JustMeNoOther: Hi, just a doubt, I have a B&S lawn mower and when I push the primer but I do not see the fuel jumping and of course do not start, I clean the carb and all the holes are clean and without obstructing... but when I spray 'easy start liquid' into the carb entrance the mower starts perfect and I see the fuel jumping and feeding the engine... what I'm doing wrong? Thnaks

Pgxi: thanks dony, i never replaced one on tecumseh i was wondering how it was fastened to the carb....good information

Bruce Wayne: Thanks for the video. You make it look easy. Now to make sure I order the correct replacement piece.

TheCaddy84: Knowing this can save a LOT of mowers. Do you have a vid on the symptoms and strange off beat Rhythm sound of one running with a cracked bulb?

mikebrady721: thank u very much my primer was cracked and mower keeped stalling watched ur vid...bought the bulb 4 6.00 dollars and replaced like u said ........3 primes and 1 pull later and it works fine thank u again........

Moparman58: @ncrdisabled they have after market parts. but tecumseh isnt bankrupt they just dont make engines anymore, they make compressors.

mikebrady721: thank u for saveing me a lot of money watched u vid....bought part 4 6.00 dollars took 10mins and 1 pull mower works fine......my primer was craced and mower keep stalling.....u can do it ............:')

cultwho: thank you, for showing the part number, the generic one size fits all doesn't work, you're saving a lot of people a lot a trouble (like me with the part number because Sears doesn't list it) From everyone who get to have fun instead of working on their mower I wish we could pay you some of that fun backers. Thanks dude!

Twisted86: I have a 15 year old craftsman and it will randomly die, sometimes it will work for 3-4 full mowings with no problems, other times I will start and go 20FT and have it rev up and down 3-5 times and die, other times I will get through half my yard before it happens and it will die and take 10-15 minutes before I can start it again. Any idea what could possibly be causing this issue? I do basic maintenance on it like oil/gas/air filter. One time when it died it spit out gas from the primer.

foreverwood1963: Man the socket is a great idea

Rarrin9378: @donyboy73 Ok good because I already ordered one and wasn't sure lol, Thanks!

Chris Woods: Replaced mine late last summer, primer bulb never worked. Found this video, pulled the bulb off, realized I didn't remove the retaining ring from the old bulb. Pulled the retaining ring out (and the rubber behind it), cleaned out the area with a screwdriver, then re-installed the bulb with a 19MM socket and rubber hammer. Wouldn't you know it, started after three primes. Thanks much for this video.
