Question about Homelite Consumer Products 9.0 Amp, 14 In. Chainsaw

1 Answer

Bought a new UT10520 in 46cc Homelite Chain saw last year and it did not run well out of the box. It would die or hesitate when going full trottle. I was parallel cutting a large log. I adjusted the L carb valve about 1/8 turn open. It helped some. Once I got it going the engine got very hot - dumb place to put the exhaust (right in front of the saw where the heat can't escape). Now when it gets warmed up the engine will race without throttle. Are there head gaskets that blow on these little engines or it is a carburetor adjustment problem.

You should have taken advantage of the warranty when you first noticed the problem. Go to: http://www.drystacked.com for an excellent 12 page article on Walbro carburetors--theory and troubleshooting. Note carefully, the caution about the lower chamber gasket and diaphragm positions. Hot running engines imply very lean fuel conditions. Hopefully, you haven't damaged the inner cylinder liner/piston/rings due to excess heat and lack of lubrication. At 50:1 fuel ratio, there isn't much lubrication to spare. Make sure the carburetor fasteners are tight and no plugging of the fuel filter. The head and cylinder are one casting--no head gasket. Try turning both jet screws CW to the stops (lightly), then back out each CCW 1-1/2 turns. This is a basic setting and the engine should start and run. Allow to warm up, then pull the throttle full on--adjust H needle CW until the engine speeds up, but continues to 4-stroke. Proper adjustment is when the engine 4-strokes, but immediately 2-strokes when cutting. This produces the most power and least heat. Allow to idle and adjust L CW until the engine runs fairly well, but allows the engine to 'follow the throttle'. Adjust the idle speed screw to stop the chain from turning, but keeps the engine running. Hope this helps!

Testimonial: "Thanks for the instructions for adjusting the carburetor and the reference. The saw runs great as long as it stays relatively cool. Once it heats up it no longer idols. Wondering if it has anything to do the the etholonol that is used in our gasoline in this state. It acts like it evaporates before it gets into the cyl. for firing. "

    Actually, the ethanol in the fuel should make the engine run cooler, but in turn, it makes the engine tend to run lean which makes more heat. I use ethanol/gasoline in both of my saws without problem. Check the throttle mechanism which may be binding (not releasing fully) when it gets hot. Remove the starter mechanism and blow out the case and engine with compressed air to get rid of accumulated dirt and sawdust. Make sure that all of the carburetor fasteners are tight. Good luck!

Left gas in my HOMELITE UT10516/16 in. 33cc. chain saw FOR LAST 2 YEARS. WHAT TYPE OF CLEANING WILL I HAVE TO DO TO GET IT BACK IN RUNNING CONDITION?


Get an overhaul kit for your carburetor. Rubber parts need to be changed not simply cleaned. Gasoline handled properly will clean the carb or you can get a spray on product from any auto parts store.

Carb ajustment


Only Info I see is "Homelite Chain Saws" - not much to go on.
Most saws have two carb adjustment screws, Hi, and Lo.
Assuming the saw will start and run enough to warm up, then
adjust the Lo screw in, clockwise, until the motor starts to slow down,
turn only about 1/8 turn at a time. From the point where it starts to slow down, turn it out about 1/4 turn. This should give you a decent idle. Now pull the throttle, and see what happens.
A - Saw runs up to speed, but dies off, or starts to slow on it's own.
turn Hi idle screw out about 1/4 turn.
B - Saw speeds up, but runs sluggish, fat - not real hi end.
Turn Hi screw IN, about 1/8 or so, and try again, or adjust
while running at full throttle. (best way)
IF it won't run well, try turning both screws all the way in to seat them, then come back out about 1-1/2 to 2 turns. this should get you in the ballpark to set things up as above.

Once the saw is running well, adjust the idle screw to a smooth idle but slow enough that the chain stops moving.

Stay safe

Started homelite 16 in (the jd 3816 model- new plug and started on a small dose of raw gas--got it running but won`t open full thr ottle- this saw has had very little use- oh put in new j-8 plug but once...


Either that season's gas dried in the carburetor affecting it's operation or you are drawing air through a fuel seal somewhere. Both are common with this model. Sometimes will start from cold and run up to half speed until you take the choke off. Then it just dies from not drawing gas. Status proved if it revs up if sprayed with short blip of ether from 7" away at the moment it dies. Do not try to keep it running on ether more than a minute. Like pure gas, it'll burn up the engine or worst. Do not use ether if the air is not moving. Ether may collect and explode.

What is the oil to gas ratio for a homelite zr 10926 16 chain saw


This is a current Homelite product although not your saw. This clearly recommends 50:1 as do I. I find no OM for your saw, a "Ranger 33cc 16" Chain Saw UT-10926"
http://www.homelite.com/product_manual/file_url/66/UT10540_60_80_QSG.pdf
Dolmar, Echo, Efco, Homelite, Husqvarna, Jonsered, Makita, Oleo-Mac, Red Max, Ryobi, Shindaiwa, Solo, Spear & Jackson, Stihl & Tanaka; all recommend 50:1 and have for a number of years.
1 gallon of premium fuel to 2.6 ounces of quality 2-cycle oil.
4 liters of premium fuel to 80 milliliters of quality 2-cycle oil.

I suggest you contact Homelite and request an OM for your saw.
Homelite/Ryobi.com (Contact Us)

Please ask they prove a link to a site where ALL homelite product OMs may be accessed.

PETROL ENGINE WORKS FINE BUT SAW CHAIN DOES NOT FU DOES NOT DRIVE


It is possible that the clutch has froze, could try taking the side pannel of and seeing if it spins freely with out the chain bar on. If it does, it could be a problem with the chain, make sure its not tightened up too tight and that the chain can move freely over the bar.

The answer to your question can be found here:
Chain Saw Collectors Corner
http://www.acresinternet.com/cscc.nsf
Click "Chain Saws", then "next page" once, cursor down and select "HOMELITE CORPORATION", keep selecting "next page" until you find your model. A "MIX OIL SPECIFICATION:" appears on the page. the listings on these pages are not alpha numeric. ABC often follows XYZ and 25 precedes 10.
2 cycle oil technology has improved since this saw was purchased. I use Stihl 2-cycle Engine Oil to operate a Pioneer I bought new 1980. My manual says 24:1. It was operated at 32:1 for many years, the last 5± it runs at 50:1. I suggest you run it operate at the mixture recommended by the OIL supplier. HTH
