20 Most Recent Husqvarna 450 e-series 18" Chain Saw Questions & Answers

Verify carburetor linkage and throttle shaft are not sticking (remove linkage as a test). The intake and carb assembly are several components. There can be no air leaks at any point downstream of the throttle plate. Check mounting screws are properly torqued. Could also be crankcase leak. Check fuel tank is not building pressure (remove/loosen fuel cap as a test).

I fear you are correct about the oiler problem. I see a lot of oiler problems on these saws. Sooner or later Husky will have to address it. Ask the dealer about modifying your oiler; the 350 has an adjustable and might fit 1 or both of these saws. I think Husky needs to admit the nonadjustable is a mistake, and come up with a fix.

If you want to do some research start with the IPLs here:

Enter the 3 digit model number (no XPs, Es, just the numbers)
Serial number decode – useful when downloading IPLs and Manuals
06 1500198
06 = year produced – 2006 (single digit before 2000)
15 = week produced - March
00198 = 198th unit Husky produced that week
Please post back (below) with what happens at the dealer. Take your buddy and his saw with you! Good Luck. HTH

If Husky starts modifying all these with 350 oilers I want compensation...LOL

Hi. Beside where the fuel line go through there should be a small nut with a spring beneath it. Turn that slightly to allow more fuel through. ONLY DO IT A FRACTION AT A TIME.

450 does not have a cylinder head. The cylinder assembly is one piece. The cylinder assembly is connected by 4 bolts installed from the bottom of the saw.

Check to see if the primer is split or leaking. Then check your fuel filter and fuel lines. If all are clear and no leaks, the only other issue would be carburetor or lines installed incorrectly.

There is not much wiring on the 460. The coil has the lead to the sparkplug, then there is the ground (kill) wire running to the switch and grounded to the engine.

The adjustment handle snaps down to lock. If the handle is coming loose, I recommend replacing the handle. You can also go to standard bar bolt set up if you prefer. Check with your Husqvarna dealer for part numbers.

Pretty sure it is 50:1. You can check right at your Hardware BOX store on line to verify that. The "Blue" one in the US especially.

check oil pump, oil pump drive gear, and rubber oil guide tube isnt blocked

Have you got chain brake on

ask husqvarna Sweden ( the can answere you in your language

you tube has video's on how to do this

The primary jet is probably clogged. If you remove the fuel bowl and float assembly you should be able to slide a fine wire through the orifice to clean it. Rinse everything with carb cleaner before reassembly.

If the choke is not fully opening, that would cause this problem check this first.

The grey plug in the base of the oil tank is the oil filter it will twist 1/4 turn and pull out, to replace push back in and turn 1/4 turn there is a leg on it that locks into the orange tank, there is a screw driver slot in it to assist this, they can be really tight try not to force too much or you will break it.

the oiler is not adjustbale.

chain oil is not ajustable. the pump is most likely faulty or the oil ports blocked.
