Straight gas brand new chainsaw

[Rosss]

I saw an ad for chainsaw- gas powered for sale cheap

I and curious and call, the guy knows it is a Ryobi but has no idea what model. I get him to look for numbers and letters on the saw and he find the model number since I was typing it into google and it came up in the search.

We talka bit more and he tells me he has only run it briefly and he just put gas in it and it started up but then started to smoke and he shut it off. I ask him how long it ran he says maybe 10 seconds.

I tell him he needs to put 2 stroke oil in and he asks where... so he straight gassed it on first start up for a brief period of time.

I passed on the saw, although I might be able to trade him some stuff I can't use that I got for free for it.

Thoughts on the brief straight gassing?

No oil to lube a bare cylinder, and you know gas does not lubricate anything.

Would need to pull muffler to inspect.

Or just get the receipt from him and take it back where he got it and tell them it won't start and want to exchange it. Lowe's or Home Depot, can't remember which one sales it.

Plus the bottom end bearings would need looking at maybe worth "fetterling" but could end up as parts

Ryobi sells complete engines for these type saws for 60 bucks or so. Problem is after you put 60 bucks into one, you have a 50 buck saw.

It might look like this.

Running 10 seconds on straight gas with no load will not harm a saw. Problem is his opinion on 10 seconds and another persons 10 seconds are different. Only way to be sure is to pull muffler and look.

Throw away saw. If it has p/c damage, it’s a parts saw. I’d pay $20 max if the bar & chain are in good shape only if I wasn’t already frustrated at tripping over saw junk in the garage.

If it was smoking then I would tend to think that's a good sign.
That's likely a lubricant that was used on assembly that was smoking.
Perhaps a quality 2 stroke oil?
If it was to happen then that would be the best scenario.
I believe it was infact Yamaha that came out with the jet ski/PWC that automatically shut the oil injectors off at idle for when they came into the populated beaches to cut down on all the smoke. I believe it was good for ten minutes max. Not sure if it would shut it's self off or had a beep and red light much like the liquid cooled snowmobiles for temps or would start sending oil again?
It was said to work very well though.
You would have to look at it though

I would think that if it ran long enough to start smoking, it ran longer than ten seconds.

 

[Rosss]

my guess is that if it was smoking that it was burning off some of the protective oil that would have been on bare metal surfaces to protect them.

I also assume that the saw internals would have some lubrication on them as part of the assembly process so they wouldn't start running with out lube until the saw had had enough gas mix to go through it to provide lubrication.

The guy knew nothing about it needing premix and his only incentive to try to minimize the amount of time it ran was in relation to wanting the saw to be new to enhance it sale-ability.

Still on the fence about putting any more effort towards it.

I'd pull muffler to see how it looks and go from there.
