great informative video!!!

[@HomeGaragechannel]

zmanvideo1 thank you. I appreciate it.

[@paulhatch8451]

Do remember the part numbers on the kit? I bought this model for $20 and it needs a carb rebuild. Also need a part number for a air filter and the cover. When I bought it, it didn't have one on it.

[@HomeGaragechannel]

It would be easier to go to Ereplacementparts dot to find the parts you need. Thanks for the comment

[@gamebug1152]

I always put my hardened diaphragms in brake fluid to loosen them up :D also niiiicceee video

[@HomeGaragechannel]

Thanks as always. Brake fluid seems to be the best way to make them flexible again.

[@gamebug1152]

hmm yeah that's a better idea but sometimes I just like cleaning and fixing parts on carbs for some reason

[@HomeGaragechannel]

You are correct carbs are cheap nowadays. That was option number 2.

[@joesphbaumgardner4579]

@Home Garage, my blower layout is very same as yours.Just mines a Polan pro that I got used past week ago.Issue is, starts runs.About 5 min then cuts right off like a kill switch.I have broke blower down.Cleaned.New spark plug lines bulb filter and fule filter.Only thing I seen was coil looks wore down in middle.Pretty large gap.Other side is fine gapped like a business card.Same issue when all done..Never messed with carb except to clean outside.Flushed it with carb cleaner.I run 90 gas no ethanol.Sthil hp oil mix.What I suspect is owner ran crap gas left sit.Lines was white inside.I suspect carb issue.Although confused because runs like a champ for 5 min.Dies has to sit min or so to start.Motor does get very hot.When running it runs smooth.About all I know is for the sec that it has a Zama carb.100% looks like yours.Now I had a friend had a Craftsman would not start.I ordered him new carb.Was 100% researched and sub part per Craftsman was what I ordered.Carb arrived and was little off and no match.So, little worried about buying cheap carbs.Do you have a link for the part or rebuild you put in yours? A link to a good carb also same as yours?

[@HomeGaragechannel]

Thank you Joseph Baumgardner. I hate to say it but its definitely the carb diaphragm. The easiest thing is to order a new carb for $15 vs the rebuild kit on Ebay. Yes its risky cause you can order the wrong kit but the only thing to do is ask the seller which carb will fit your particular model. Let them work for you. Send them pictures of all sides of the carb and let them figure it out. I don't have any particular link I use. I hope this helps out.

[@joesphbaumgardner4579]

Home Garage, I understand what you say.I order alot of parts both electronic and stuff.Got alot of knock offs out there listed.Problem with guys carb I ordered was, per the factory book that was part # sub.The seller did send me that carb.Just did not match 100% mainly start run area.Course came from China, but seems most stuff listed does.I hope carb is issue vs motor compression and so on.Or find the air flow leak game.Guess I'll attempt a parts list break down see what carb go from there.

[@joesphbaumgardner4579]

@Home Garage, I have same leaf blower I got today used.First, I would like to touch on a topic that puzzles me.I have had used leaf blowers like this style.Polan etc.Older.Some ran some issues.I see that the motor gets hot fast.Really hot.Spark plug gets real hot also.Put a new one in and 2 min later take it out and looks white chard like.Any how, what causes motor to run so hot.I would think this is not good, but wonder if normal being I seen it time again? Next, back to leaf blower at hand same as you have.Starts and runs.Some times bogs down and up.Some times throttle wide open runs then cuts off.I also have the issue of have to run half choke.Full choke and it stalls.I replaced fule line.Fule filter.Took card apart and cleaned ( seen gum build up on small round silver screen ).So, to me it seems starve of fule.Thoughts? If carb or part you replaced, could I get the part number or link please.Side note- spark arrestor can't be removed.Although looks clean enough.Part you replaced, mine looks flexable although kinda bubbled up in one spot.Guy said blower been sitting a year drained gas out tank and carb.Course who knows how long gas has sat in it.But any how blower I picked up today is same as yours so fig you have hands on with this one.Craftsman vs the Polan I talked of while back which oddly other day used it was fine.Next day try to start and dead not even attempting to turn over.Spark tester shows I have spark.

[@HomeGaragechannel]

Joesph Baumgardner thank you for your long comment. If the blower gets extremely hot then it's running too lean. Either adjust the hi mixture screw or find out if there's a fuel obstruction.

[@HomeGaragechannel]

Joesph Baumgardner second question if the engine runs good and runs bad while squeezing the throttle then make sure the metering diaphragm is not semi stiff. It should be pliable.

[@HomeGaragechannel]

Joesph Baumgardner please consider getting a new replacement instead. Make life a whole lot better.

[@joesphbaumgardner4579]

Home Garage, thanks.Just attempting to give much info as can to help.So, I assume safe to say sounds like a classic carb issue.Both the Polan and Craftsman got hot.One thing I never messed with is the ajust screws.Also with my luck would get all out of wack with small run time on this Craftsman in ajusting getting it to stay running past a min or so if lucky.I can say my gas is good 90 no ethanol Sthil hp oil.So, if I replace carb can I hit luck without ajusting messing with lean screw etc? Another words new carb "should " be ajusted fine?

[@HomeGaragechannel]

More than likely you'll have to adjust the new carb to the blower.

[@electroddxful]

I have the same leaf blower I would like to know where does the gas filter goes on the smaller hose or the big hose in the tank.

[@HomeGaragechannel]

Thank you Ray Lugo for the comment I appreciate it. I believe both my lines are the same size but it's not important as its which ever line that goes on the carb towards or closest the silver plate.

[@hectorromero8191]

My blower is missing the smaller hose(I believe it's the return line)inside the gas tank,,could that be why it won't stay on very long before cutting off by itself?

[@jordanallen8523]

Where did you find the carburetor screws? My leaf blower has a similar layout, but I can't find the adjustment screws to save my life

[@HomeGaragechannel]

Some don't have screws. Or they are capped off so they can't be tampered with. Thanks for the comment.

[@PKwhl]

@@HomeGaragechannel but u said u adjusted the screws. Lost faith in your videos. not helpful

[@johnlangen966]

I have a 27 CC Craftsman bowler that starts just fine but when you put it in “run” position it just shuts down. It will only run when in high throttle. Need some help thanks

[@HomeGaragechannel]

Thank you John Langen for the comment. Look for the carb adjustment screw marked "H" and "L" . Try turning both counterclockwise a quarter turn. See if that helps.

[@tdriver3090]

I have same problem.almost... my 27 cc blower starts and runs but when accelerated it boggs down n shuts off... Took it apart cleaned the carb and then checked the spark resister still same thing. Not to sure what else could be someone in neighboorhood said same thing about adjusting the Jets but Im not to sure

[@smlrglobal1]

Need to know where to get parts!

[@HomeGaragechannel]

Amazon

[@buster2725]

[@artob]

Fuel filter link is for Husqvarna blower....did it fit the craftsman in this video? Thanks for the video!

[@HomeGaragechannel]

Yes it does

[@artob]

Thanks for reply. Could you add link to diaphragm you used to replace?

[@HomeGaragechannel]

the link is in the description

[@artob]

@@HomeGaragechannel got it. Currently unavailable 🤷‍♂️ Oh well. Will just have to contact Craftmans part replacement and get hosed on them.

[@HomeGaragechannel]

@@artob I'll post a different link thanks.

[@chadjenkins186]

Hello I'm fixing the same blower, what size are the fuel lines?

[@HomeGaragechannel]

Thank you Chad Jenkins for the comment. The fuel line size is .190". I buy it at Ace hardware by the foot. The line is okay it really doesn't like ethanol tho.

[@chadjenkins186]

Home Garage I got it fixed but it runs a bit hot. Any ideas? Where should I set the carb screws? I put on a brand new carb and fuel lines. Air filter seems decent.

[@angelbarajas4564]

Hi I was wondering if this works for all leaf blowers

[@HomeGaragechannel]

If it has adjustment screws but it won't help if there is a carb problem

[@aaronzaffle2479]

Can you tell me what the rebuild part number is for this blower

[@aaronzaffle2479]

Or if they sell the entire carb could you give me that part number too?

[@HomeGaragechannel]

Thank you Aaron Zaffle for the comment. I didn't use a rebuild kit. I reconditioned another diaphragm so it was pliable again.

[@HomeGaragechannel]

I can try and figure it out. I'll try tomorrow.

[@HomeGaragechannel]

The rebuild kit is a walbro k20-wat.

[@deenut2927]

Where u get the kit from

[@HomeGaragechannel]

Thanks for the comment. Ebay.

[@danieldickerson7974]

My problem is Craftsman leaf blower won't stay running after I take my hand off the trigger

[@HomeGaragechannel]

Thanks for the comment. So basically it won't run at idle only at full speed? If If that's the case try replacing the carb. If it's not the case try just increasing the idle speed till it doesn't want to die.

[@MotivativeThinking2]

Where do you get your parts from? I have the exact same blower. My diaphragm and the two fuel lines are dry rotted. One of the fuel lines was very brittle and broke off in the tank along with some hard thing like a float.

[@HomeGaragechannel]

Thanks for the comment I appreciate it. Mainly ebay. Replacement parts is also a very good place to start.

[@MotivativeThinking2]

Got it! Keep the videos coming! Thanks for all your help!

Craftsman blower following start up half choke blower turns off when going to run why?help

[@adoniscarter74]

Model 358.794740 _200mph 430cfm

[@HomeGaragechannel]

sure, try turning the L screw on the carb, about a quarter counter clockwise, and to compensate for the extra fuel, you might have to turn the Idle screw clockwise about half a turn. You might need a special tool to turn the L screw though.

[@Maybe1Someday]

Why does a small engine need a diaphragm?

[@HomeGaragechannel]

It's what controls how much fuel to deliver to the engine. When it starts to stiffen then the reduced fuel delivery to the engine doesn't allow it to work at all engine speeds.

[@Maybe1Someday]

@@HomeGaragechannel thanks, id guess thats why my blower only runs on start and the. You cant give it gas when its on run

[@HomeGaragechannel]

@@Maybe1Someday yes it would seem to be your problem
