I got this ugly 044 running today, I had rebuilt it and it would not even hit. It turns out that it had a dud spark plug. Both the husqvarna 455 and the shindaiwa in the background were rebuilt by me and I just finished them.

To make that Stihl look better, put the Husky in front of it.

It was already running when i got it
I just have to determine if it runs good enough to use lol, i kinda tested it out while i was there after i retuned it and it seemed to idle good without speeding up and the throttle response was great, ill have to see if it holds steady at WOT and it will be ready for wood

I don't know, going to have to see some videos of it in wood before I believe you.

Yep ill work on that sunday

Just my 2 cents on the governor issue.

I have an HS-176 that was giving me the same gradual lean out at full throttle. The saw held good vac and pressure numbers. I blocked the governor off and all was well. I tried a few block off sequences and some didn't work. What did was;
1/4" OD piece of aluminum beer can punched out with a paper punch in the bottom of the governor hole
Next is the copper washer / gasket
Last the governor in with some thread sealant (I used Motoseal)

I found if the washer went in first it didn't block the governor off.

That solved the issue.

The other thing I always look for on HS carbs is for a worn throttle shaft. That will leak air at different rates in different positions and cause all kinds of odd symptoms. The ones I've found that were worn did not have any wear in the carb body.

Thanks. I'll give that a try.

Well, I splashed a little fuel in my 5200 carb today so I could hear it run for 1 second. Still haven't found the fuel line size I need. Hate to have to order it but looks like I will.

XL870 just passed both pressure/vac test with flying colors.
Reeds & reed cage are flawless.
Has new fuel lines, fuel pickup and tank vent.
Gotta be the carb.

Nice one did you check it to see if it has the boost port?

Good stuff!

I did, it has the boost port right across from the exhaust outlet , i just need to see what carburetor it has, its not the ungoverned SDC 80 which is so desirable, it has a governed Walbro WJ i think.

 

[Kensie1988]

Man that governed carb doesnt let that 655 turn over 10,300 lol

Got to working on the XL870 again, did what @fossil said with the governor. Let the thread locker dry for 24 hrs and just recently fired it up. Still ran lean at WOT, gradually building RPM till it shut off.
Although, I did fix it. I put a different spark plug in it. Had a E3.12 in it. I've used those plugs in a lot of saws without any problems at all. But, for some reason I decided to change out the plug. Sure enough, with the new Champion plug installed, the 870 no longer shuts off at WOT, and four-strokes somewhere around 10,500 RPM.

However, the high speed screw is out about 3 turns. If it's turned in any further, it won't four-stroke.

 

[s sidewall]

I use ngk or champion

Steve

 

[happysaws]

Got it to four stroke with the high speed screw out 1.5 turns. Good to go.
Thanks to all who helped!

 

[Kensie1988]

I guess ill try a different plug and see if that helps.
