Marks on cylinder wall

[CaseyForrest]

OK, Ive got a full tank through my 441 so far. I took the one off the floor because a member here stole the one in the box out from under me!!

Anyway, I was wondering if pulling a saw over that has never been fueled will eventually scratch the cylinder walls. Everyone knows, and I'm sure we all do it...walk up to a floor display and give her a few yanks to see what it feels like. I don't do it anymore because I figured it wasn't good for the P&C.

Reason I'm asking is after I cut up a load of logs, I started cleaning the saw and figured id have a peek around to see whats up....Pulled the muffler to see if the internals looked any different from the other 2 saws I have. No scratches on the exhaust side of the piston, but did notice the bottom of the skirt on the exhaust side looked "polished." I realize I can see the entire skirt though the exhaust port, but I did see a bit of polishing.

On the intake side there appeared to be what looked like light scratches. Not really gouges, and not sure if they were deep enough to matter, but definitely noticeable.

Question is.....is repetitive pulling of the starter on a saw that has not been run bad for the P&C?

I would think not

Should be plenty of assembly lube in there.. If it was bone dry it would be almost impossible to crank over.

 

[CaseyForrest]

what if the saw has been sitting there for a couple months?

 

[Tree Sling'r]

There is lube of some sort in there. When I port a cylinder I run the piston up and down it a lot to match my work with my piston, also when I check squish, BDC and TDC.
I would not worry.

 

[CaseyForrest]

OK, I realize there is lube in there. But at what point does that assembly lube dry up? or get to the point it no longer protects from metal to metal contact?

At some point, without the addition of new lube i.e. fuel mix...the assembly lube must wear off, or start to soildify.

Without knowing what the lube consists of exactly, I'd say a long damn time. Maybe if you bought a NIB saw from the 80's you'd have a problem

Maybe the guy that beat you to the one in the box. Grabbed yours and cranked on it for awhile!:hmm3grin2orange:

HAHA!!! Ill have to ask him!

A woodchuck could chuck as much wood as a woodchuck could if a woodchuck could chuck wood.

LOL

Yea? But how much is the ?

There is no assembly lube in the store saws - they have been run at the factory for about a minute at full power. What remains is the residual from 50:1 mix.

I wouldn't sweat marks or slight polish the lower skirt on your piston - I see that all the time on new (hour or two run time) saws. I figure its part of the break-in process.

I also doubt if "pulling over" can materially affect a saw.

I must have crancked it over a couple dozen times.:hmm3grin2orange:

Funny I never even cranked the floor model. Put the demo thru its paces tho.:biggrinbounce2:

I had mine ordered before you called that night. :biggrinbounce2:

I have about a gallon thru mine. Haven't checked the the pc yet maybe after the next gallon. Still really like it. How about you?

I also would not worry to much about light scratches as they will probably go away with use. I think that I have seen what you are talking about in a couple of new saws and attribute it to contaminates in the cylinder area. The only saws that I have been able to "track" have not had any issues. I got to peak inside one not to long ago and it looked better than I remembered. Sometimes it is hard to convince a friend to allow you to dismantled his almost new and not broken saw, but we got to see and learn about his new tool. He is all happy now. Trying to talk him into an 880. Set up from the Poulan.

Allright, thanks guys.

Wally, still waiting on that tach, I made the decision Im not going to run it untill I find out where its at. I feel the 441 is just like the 361, cant tune it by ear otherwise it will be running way rich.

Good info, I have been a bit conserned that my 361 doesn't "four-stroke" like my other saws......:rockn:

Yes, you'll need a tach on the 441... It is a very lean running machine.

Troll - you'll be better able to tune by ear if you never get your new muffler - soon, I promise... but first I needed my health back, and now I just need power...

That's cool, as I said - I am not in a hurry...... :rockn:
