Homelite Gas, 20 In. Bar, 46 CC, Chain Saw, UT10520 - Answered Questions & Fixed issues

Refers to the spark plug gap.

you could either use an organic rubber type simelare to platsiic and do it urself - size etc

I think this sounds like a fuel starvation issue, depending on the model there can be numerous pipes from the tank, if it has a fuel primer bulb there will be a pipe from the tank to the back of it, there will also be a pipe to act as a breather to stop a vacume building in the tank, and finally a pipe directly to the carb, if there is a leak from this pipe you will have problems, on the tank end there will be a filter on the end of this pipe, if it is blocked it will cause this type of problem

Sounds like the inner cable is too short, what you can do is gently snip off a peice of the outer cable where it anchors, this will make the inner longer.

lI thinkthe oil to gas is too rich with Gasoline. My book says 40 to 1. Not enough oil will cause it to run hot and burn or stick. Also some of the later models take the synthetic oil andif you use the outboard or other oil it will run hot and ruin the saw.

Hi,

The ratio is 50:1.

If you appreciated my help, I'd appreciate your vote. Thanks,

return it, any repairs from you will void the warrenty

Hi,

Turn the tightener till the chain in the center of the bar at the bottom just hangs down about a 1/8"....
this will be good... too tight and the chain will not turn...too loose and it will come off...
that 1/8" is usually great for any saw...

ther is fuel mixiture problems- if it is under warranty - its dann give warranty repair.

To the best of my recollection the 330 is an older model saw and should be running about a 16:1 ratio. 8oz. of oil to 1 gallon of fuel. Hope this helps.

Note: You're always better being a bit richer (lower ratio) than you are leaner (higher ratio).

strip cover and check that all the dirt etc is cleaned out and the brake band is in the correct position If the brake band looks worn ie thin in places replace with new one. Dirt can also get in the pivot of the chain brake handle and cause it to jam, saw should be stripped and cleaned at the end of every days use and the bar turned over to even out the wear

First thing to do is remove the top cover, now check that when you release the throttle trigger the spindle on the carb returns ahainst the idle screw stop, if not check the linkage is not sticking and holding it open, if ok make an adjustment to the idle screw, if this screws right out and the revs still do not decrease, then you have an air leak through a crank seal or gasket.

Threr will be three adjuster screws on the carb ( will be holes in the cover so as to acess without removing any covers ) they will be marked L H and I( for idle ) or T( for tickover ). The T or I screw will adjust the idle speed, unscrew anti clockwise to reduce the speed.

50:1 is the fuel to oil ratio using a modern synthetic saw oil available at home centers, hardware stores, and saw dealers. Be sure to mix the fuel and oil in it's own container, and to shake the container thoroughly each time just before filling the tank to prevent oil starvation. Hope this helps!

If the chain is showing signs of heavy wear, suggest replacing both the bar and the chain. Check the sprocket on the clutch hub for heavy wear on the teeth which will hasten wear on the chain teeth. Check chain oiling by running the saw tip near some cardboard at speed for a moment or two--it should throw off a thin line of oil. Tighten the chain until the lower run of chain just comes up to the bar, but not so tight that you can't turn the chain by hand. Hope this helps!

Question edited for clarity and spelling.. Please don't type in all CAPS, it is classed as SHOUTING and harder to read. There is no wiring diagram for it online. It is just a mains lead, a switch and a motor. Parts schematic and a link to the company support. https://www.google.com/search?q=homelite+lawn+mower+ut13124+wiring+diagram ..

The fact that is runs slightly longer on full choke may point still to a fuelling issue.. Does it actually Rev in those 10 seconds or does it just want to bog down and stall.?

Is it in the right way? They only work in one direction. They can also be faulty from new.
