Husky 371XP... belching white smoke

[TFPace]

My 371 XP sits un-used most of time. The 550XP is no my favorite saw.

I go to fire it up and it only runs with the choke pulled out. The white smoke it blows out is amazing? I'm guessing I have had a seal failure and or am pulling in bar oil into to combustion chamber too?
I've never had this happen to my Husky's ... obviously

Thanks for any advice. I'm guessing a Might Vac test kit is in the work?

If it will only run with the choke on then i would be giving the carby a good clean out first. It could also be a cracked fuel line. The smoke would be from running too rich with the choke on.

White smoke leans more towards bar oil leaking through the crankcase gasket.
My turd 076's have leaked bar oil before. A freight trains volume and White.....

Pull the muffler and have a peek at the piston. Bar oil will scorch it.

Alex, the amount was amazing. WOW.

I didn't run it long

I've seen old fuel do that. Dump the fuel and put a kit in the carb.

Here's a pic of the clutch. And the oil.

Start with the simple stuff...fuel and carb kit.

Thanks Brad,

I tend to do the exact opposite

drain and rinse out the oil tank, run it with out bar and if it clears up its the case gasket.

With the bar oil removed and rinsed I should have no white smoke? I started this saw with fresh fuel so unless the carb is the problem I'm guessing a seal failure.
The clutch area is really wet.

I'll report my finding.

Thanks everyone.

I miss my old 371. They are good ole saws. I want to buy another....

If you have children who are anywhere near as pesky as me and my brother were then flush your fuel tank and replace the fuel mix in your can. Lol

You didnt accidently put bar oil in the gas tank did you. Dont ask me why I say this lol.

That's normal if you piss rev your saw

 

[TFPace]

Roll Tide,

help me on the term "piss rev" ???

 

[Roll Tide]

Piss Rev- revving your saw uncontrollably. That's what causes all the oil you see in the picture. I'd agree that the white smoke is from bar oil not a bad carb or fuel line.

The infamous piss rev

Also sniff the fuel for diesel odor. I have heard of fuel suppliers trucks accidently making mix mistakes with types of fuels, and gas cans being used for diesel with a couple inches left in the bottom can.
Some diesel in your gas make a pretty big smoke cloud too.
I get cutoff saw in regularly that reek of diesel.
