290 fuel line

[Deleted]

I picked up a nice 290 yesterday for $15.I didn't get a chance to give it the oncer over til today.I pulled the muffler & saw a beautiful unscored piston & cylinder.Next thing I did was check for spark - it didn't seems to have any that I could see.Next was to take a compression test,it came out at 160 psi.Next step was to squirt some fuel in the carb & see if it would fire up.It ran perfectly til the fuel ran out.While standing there looking at my latest acquisition,I noticed that the fuel line that comesd from the tank & is supposed to go to the carb was cut (so I thought),& about 1 - 1 1/2 in.from the end I could see that the line was pressed up against the cylinder & had melted shut.I thought "well this is simple,I'll just replace the line".For the life of me I can't see,or figure out where the line attaches.I took the carb partally off,& still I can't figure out where the line goes.I had my son look at it to see if he could see where it's suposed to go,but he didn't see anything either.

The fuel line goes to a barbed fitting on the right side of the carb.... also rear (high?) mixture adjustment screw/spring missing.

Judging by the IPL, there should be a brass barb on the right hand side of the carburetor: www.leonschainsawpartsandrepair.com/uploads/3/9/7/9/39792537/homelite_290_340_chainsaw_ipl_17867_2.pdf

That hose in the picture also looks way too big...hopefully the tank isn't hogged out.

The idiot that installed that garden hose in that saw needs a shovel to the back of the head. Blazing Saddles style

I have a 340 as well,but it's toast.The muffler was already off & when I looked in that one's cylinder,let's just say it wasn't pretty.Would the carb from the 340 work on the 290? Whoever "worked"on these 2 saws totally butchered them - the line from the tank on the 340 was cut as well.I went to the 340 as a reference to see where the line coming from the tank on that one went to.The 340 has the same size line on that one too,so as I said,whoever worked on those 2 saws was a butcher.Probably some guy who thought he knewe what he was doing (yeah,right).I just looked on Acres'site,it just says that they both used a Tilly carb,HU series.I'll look at the 340 carb tomorrow.

The 290 & 340 do use the same carburetor.

Looks like there is a wire "clamp" around the stub of the fuel line on the carb in your picture.

I did manage to rob rhe high speed needle & spring from the 340 carb along with the grommet,but that carb had the line cut as well,& the 340 carb was missing the barb that screws inro the carb for the fuel line to attach to.Maybe the guy thought the brass barbs were gold?LOL I've got another HU carb on a Jonsered that I'm going to look at,maybe that barb wil fit,but I'm almost positive that it's plastic.not brass.

[Deleted]

Yeah,the reason that they're plastic is because they're in Walbro carbs,I'll call my local dealer tomorrow & see if he's got anything laying around.Damn,I'm so close to having it running.

sweepleader mentioned this and I saw it too.  " there is a twisted wire clamp around a stub of the fuel line" ... The yellow thing on the right hand side of the carb. where the fuel inlet fitting should be ..What is that ?? 

[Deleted]

Now here's a thought - look at the color of the line with a wire twisted around it,it looks black to mer.Now look at the line in my son's hand,it looks clear to me.So,how can those two lines possibly be the same line?The barb where the clear line is supposed to attach is supposed to be located UNDER the BLACK line with the wire twisted around it.Do you think that possibly the line with the wire twisted around it could be an IMPULSE line?

[Deleted]

I looked into getting a new barb for the carb & the reply I got was a little unsettling.It seems that the fuel inlet elbow is epoxied into the carb.It's a common thing for it to breask off when trying to get a line off that's stuck onto the carb.Tillotson doesn't list the elbow as a replacement part.I also found out that Solo used Walbro carbs on their 647 & 654 (Homelite 290 & 340)saws as well.They were WT42 & Wt108.The WT42 was upgraded to a WT 500-1 which has a primer bulb on it.I can still get the Tillotson HU63A (it was upgrasded twice to the HU63B & HU63C),but it'll cost $74+shipping.Still,if I need to buy a new carb for $74,I've basically got a new saw for $89 ($15 for cost of saw)
    But at this point I'm going to see if I can get another elbow to put on/in the existing carb.

When you press the new fitting into the carb, put a drop of Loctite 290 wicking thread locker on the fitting at the carb. That will lock it into place permanently.

Look at the 290 IPL page 4.. the line in your son's hand is #40 an 8" vent line ..the other line at the carb.(black you say with wire clamp) is #29 fuel inlet line...no impulse line there..that goes through a passage in the intake manifold. 

[Deleted]

So,where is the clear liner in my son's hand supposed to go?I get it - it's a vent line.I have to see where it goes on a real saw,not on a paper - it's too difficult for me to read it.I have serious eye problems.

You could've explained it to me how it works,instead of me going to my saw dealer & have him explain it to me.Some guys on this site are really awesome - they taske the time to explain things the way they should be explained.Then there are other guys that belong more on AS,where they think because they have some knowledge then whoever doesn't have that same knowlege,then we're no more than an idiot.I don't claim to be a master saw builder,I'm just a beginner.At one point in time we were all beginners,some went to school & learned it there,some just pick it up easy,& stil others had their dads or some other significant figure in their lives teach them.That wasn't my case.

I know what you mean, I bought my first Homelite saw in June of last year and my first chain saw just a year ago. My dad could build anything when he was home, but he sold airplanes all over he world and wasn't home a lot. I joined the Army at 17 and after 6 year stint I left and never did anything but party for nearly 30 years. I spend a lot of time reading the manuals, but nothing beats working on them. Everybody as a different path. I lie to buy saws I intend on keeping. I won't buy a saw to sell. I just hate dealing with the "what's your bottom dollar" or "I can buy those all day long for 10.00", or the best yet " the 99 dollar Poulan I bought from Home Depot will out cut any saw". The there is the guy that calls you just to talk, never going to buy, just looking to waste your time often times at 9:30 at night when he's half drunk. I've grow and raise most of what we eat so I have plenty to do. I'm still in school part time and teach a little on the side, I don't want to do anything for money, I just want to enjoy things.

I finally got this 290 fuel line business taken care of today.I had another identical carb (Tillotson HU63A) from a trashed 340,so I swapped out the carb that was on the 290.Here are pics of the carb that was on the 290.

Now I understand why it wasn't working.I primed the carb & got it running & adjusted the carb so it idles nice.I shut the saw off & tried to restart it about 5 min.later & it wouldn't restart,so I'm thinking it probably needs a rebuild kit.It idles & runs beautifully,& the auto-oiler works too.

Is that elbow supposed to be on the carb, is that factory?

Yes & yes
