Retune after switch to synthetic?

[blel]

Was just using my saw (028) with reg Stihl 2 stroke oil. I ran out of gas and put in gas with Woodland Pro synthetic. The smoke was unbelievable, ran like crap. Got it going again and gas was pouring out of muffler. Trying to retune carb but seems something else is going on. Any suggestions?

I think you have non oil related issues.I run woodland pro syn in all my saws but had no tuning issues with any of them from before when running other brands of syn, syn blends and dino.

Sounds like a carb cleaning (at least) and maybe kit is in order.

What I don't understand is that it was running great, ran out of gas, put in gas w/synthetic, started it and it immediately started to smoke like mad. It seems the smoke is coming from the gas pouring out of the muffler. It seems like there is too much gas going into the cylinder.

The carb kit is relatively new.

If I had to speculate, I'd say when you ran it out of fuel, you sucked something into the carb that is keeping your metering valve open, allowing the saw to flood.

if you have gas pouring out of your muffler than its definatly the carb. that had nothing to do with the oil you used.

:agree2:


I'm no saw mechanic, not by a loooong way, but I have to agree. That's just WAY too much of a change in behaviour to blame it on the synthetic oil.

If some experts come along and say you need to retune after switching oils, I'll just listen respectfully, 'cause I sure don't know enough about it to argue.

But gas pouring out? Something broke!

You should not really have to retune after switching oil, sometimes you can push things alittle closer to the edge with the syn. Whatever you got going on has nothing to do with oil.

Thanks for the comments. After thinking about it, it make sense that it is a carb/gas problem and only a coincidence that it happened when I switched to synthetic. I'll take the carb off and clean, etc.
