In this video Mark shows you how to rebuild your two-cycle engine carburetor using a manufacturer's rebuild kit. Parts in the carburetor wear down due the the ethanol content in gasoline, so it's important to maintain your carburetor when parts begin to crack and become brittle.

So far I haven't found carb that wouldn't run like new with just a good cleaning with the Welch plug left in place. Removing the plug would complicate the repair beyond what most of our viewers would be comfortable doing. A Welch plug removal video is a good idea and I will definitely add it to our list. Thanks for watching! -Mark

Just come in after watching your video and rebuilding my Walbro carb. Brilliant, easy to follow instructions. Strimmer now starts and runs as good as new. Thanks for sharing your expertise.

@FIXTechGuides 13 лет назад

@memberson Good question. It's true that most carburetor rebuilds should include a cleaning as well, either with carburetor cleaner or--like you suggested--with an ultrasonic cleaner. There are two reasons why we didn't include a carburetor cleaning in this video. 1. We already have two carburetor cleaner videos posted explaining the procedure. 2. We want to keep the focus of this video on just rebuilding the carburetor. Because of your comment, we may annotate this video to link to the others.

Finally a video I can learn from because the closed captioning was clear! I'm deaf. Many thank yous!

@jorg0370 10 лет назад

Thanks for posting, I liked the way the parts were laid out. A simpler rebuild, left out discussion for cleaning and also adjusting the needle lever.

@robertmcgonigle3032 7 лет назад

Thank you. Excelent procedure. I just cleaned a lawn mower carb. for the fist time from another video. Never attempted this work in the past and I am 53. Now that I have seen the steps I feel confident to rebuild the carb. on my Dad's chainsaw.

@jimmiejameswright1309 10 лет назад

Great video, I took it apart and forgot how it went back together, it shows me how to do that. Thanks Mark

@jaker5555 8 лет назад

Thanks Mark. That part that goes in the hole under the needle/spring at 5.12 was my lesson. Didn't spot that on my McCulloch Powermac 6 when I pulled the carby apart in the first two occasions. On the third dismantle, I pulled it out and cleaned the channel. Put it back together, and fired up after a few pulls. Adam. Australia.

@rayrogers5758 8 лет назад

+jaker5555 Yes mark left out several key points like cleaning, and adjustment in an outside of carb

@bfriendly100 10 лет назад

Best video like this I have ever seen! I just received my kit and should have no problems rebuilding my Ryobi Carb that uses a Similar Diaphragm, rather than a Float. Thank You!

@jted68 9 лет назад

Thanks..... Very helpful video. I followed your advice exactly and had no trouble whatsoever completing the rebuild. I found it helped to use a bench-mounted, lighted magnifying glass to install the needle valve/spring assembly. I also installed new fuel lines and a carburetor gasket.... The old IDE weedeater started on the third pull. :)

@spaderism 11 лет назад

Hi Mark, Thanks for the video! I am about to go try out a rebuild(something I never thought I would have tried due to horror stories I've heard about the process). Your video was clear, concise and professional. I am impressed. Thanks again, I will let you know how it goes.

@TheHarvey1941 11 лет назад

I like Marks videos and eReplacementParts; many hours watching the videos.This one helped me rebuild my 1994 featherlite carb...yesterday!

@paulmarkowski9794 9 лет назад

Thanks, Mark. With the kits not having printed instructions, this video was very helpful, organized and brief- perfect. Wo ever liked the printed instructions anyway? With all the junk on u-tube, this is certainly one of the jewels- Thanks!

@larrylund2682 6 лет назад

Thanks! I had it right but, just wanted to confirm before I buttoned it all up. Huge help. Really hate finding out I did something wrong when going to start the machine.

@steveweinberg3272 11 лет назад

Great video. I've disassembled that exact carb and cleaned it with a Carburetor soaking cleaner on several different 2 strokes. Sometimes it fixed the problem but from now on I will buy a Carb Kit and do it right the first time. I've started using only Non-ethanol gas in all my small engines, it really cuts down on gas line disintegration. Two strokes are very simple engines but if you let them sit without draining the ethanol gas for more than a month you will get dissolved plastic!!

@kodibassInsideoutboards 13 лет назад

@ITUMBLE4U 8 лет назад

I'm a big fan of your videos and have used several to rebuild various tools/equipment. I'm surprised you didn't suggest blowing any air through the fuel line pick up/purge lines or using any carb cleaner on it. Any reason not to?

@landa440 11 лет назад

Great video. Saved me $100, thanks

@FIXTechGuides 12 лет назад

That sounds like the fuel lines to the carb might have been crossed. Take a look at at our video about how to replace fuel lines. It will help to confirm the correct line placement. Thanks, -Mark

@Sky1 6 лет назад

clean it and make sure the ports are clear before reassembly

@JarrodZerr 10 лет назад

He makes putting the needle valve back in look way easy. That was a pain. A tip, if your carb has a primer bulb on the top, rebuild the bottom first so it sits flat and you can get the needle valve in easier! No, really, do the bottom first, you'll thank me later!

@leapord503 10 лет назад

That's interesting. I'm 15 an I know carbs normally with the bowl and floats. Last time I did a carb like this it was on a 1978 little buster go cart. Same process and everything. Thanks a lot!

@djordan4056 9 лет назад

Mark Great video, question is what is the setting for the needle valve? That would be good to post.(in thousands of an inch) Thanks.

@mythril4 10 лет назад

I remove the welsh plug to clean the tiny jets inside. Besides, to remove it you srill just through it's surface, use a pick and pluck it out. To install the new welsh plug, set it in place, use a small round tube one half the diameter of the plug and give it a couple light wacks to stretch the plug out into place, easy.

@arthursmith3154 9 лет назад

Thanks for the good video... I have a Stihl weed eater model FS 55 about 3 years old. I can crank burn one tank of gas then when I try to crank. It will fire up about one time shut down and won' start. I think it needs carburetor rebuild kit. What are your thoughts? Thanks, Art

@SurferJoe46 8 лет назад

I find a lot of warpedparts, like the Thicke aluminum over with the single screw. This seems to be the situation on mostly the Chinese versions that some manufacturers use now. What I've been doing is surfacing them one a piece of 180# wet/dry paper, masking taped to the surface of a piece of glass. These warped parts are showing in Craftsman/Poulon and a few Stihls. Husky has not had any that I've found to be Chinese.

@bsully2 12 лет назад

When do you know that you need to replace the Welch plug? Do you just puncture the plug and pull it out in order to replace it? Also do you seal the plug with anything once it is in place?

@dannymagoo 12 лет назад

I rebuilt mine using your video as a guide as I did it. My problem still exists the thing wont run. I have a troy bilt string trimmer and it just decided not to start this season.

@MENDOZA84PHANTOMBLAZE 9 лет назад

When the rubber gaskets inside carberator get hard does it flood the and leak gas out the carberator

@ellisonrepair 12 лет назад

Nice video Mark. Only one comment or question. You didn't show the correct metering lever height. I believe on this Walbro, it should be even with the carburetor machined surface. Eric

@goddale2002 9 лет назад

Hey Mark, I have an Echo PE 200 edger. I replaced the throttle body that somehow was broken on the inside of the carb. Once I was done, the unit would start and run but not while in idle. It only runs if the trigger is fully depressed. I replaced the spark plug, gas lines and grommet, air filter, gas filter, bulb, rebuilt the carb and changed the intake gasket. I use new fuel and oil mix. I used carb cleaner and air. Made sure the spark arrestor was clean and my edger still stalls when I release the trigger. I'm out of ideas??? Help!!
