Saw leaks gas while on laying on its side refueling when you stand it back up it stops then when you put it on its side to put bar oil in it leaks again

There should be an adjusting screw around the bar somewhere. Turn it anti clockwise until it stops and then just crack it one turn. If it still leaks too much then turn it down slightly.also try and store the saw on its side to stop the oil just coming out.

M/T out oil tank b 4 you put saw away
me I save peanut butter jars for this function , as my stil saw sets perfectly on the rim of one to drain oil into

Drain oil back out of tank B 4 you put away , its also a very good idea if you drain and purge gas tank as well , as either of these fluids left in saw will cause u problems if you leave in inside for long periods(< week) when you restart saw

Take the bar off and clean all the pieces and parts where the bar mates to the motor. Make sure the hole on the side of the bar, where the oil gets onto the chain drivers, is not plugged. Make sure there are no burrs, on the edge of the bar from chain wear, which will push the bar away from the chainsaw body leaving a gap for oil to leak. If your bar is worn, most bars can be flipped over and used either way. If it is made to be used in on either side it will have a hole for the oil to get into the bar on both sides. Alternating or flipping the bar will make it last a lot longer.
Something else to check is if your saw has a breather hole and if that is what is leaking or it is plugged and is not allowing the tank to breath. Not all saws have this feature.
When you store your saw it is best not to store it on its side with the bar hanging down as these position will cause more oil to leak.
Even if you have a perfect fit/seal, between saw and bar, oil will still leak if it is stored in a place with temperature fluctuations. This happens from the oil expands, when it warms up, creating pressure in the tank causing oil to leak out. I always put a piece of cloth on top of a plastic base to prevent seepage onto any surface. I run chainsaws professionally for over 35 years and they all will leak when stored in place with temperature changes. Some are worst than others. Hope this helped.

what kind of saw? where is it coming from? all saws will leak some bar oil so how bad is the leak?

It dies because it's flooding as you increase the amount of flow, a small carb adjustment is needed. As far as the leaking bar oil, if the saw has a pump replace the gaskets between the motor and the bar and reduce the amount that the saw puts out when running. Let me know if that cures the problem.

You Put mixed gas in the back, some chainsaws take a mix of 32-1 ratio. Check your manuel. Put the chainoil in the front.

First, make sure you're using bar & chain oil, it's very thick and won't leak out like motor oils will. When you're done using the saw, store it with the blade side of the saw up. Not always convienent, but the oil will run away from the blade oil channels and not leak out.

My wildthing does it too but if i lay it on its side(bar on ground)it doesnt.I have stored mine this way for years and i dont have that problem.

I think you have a cracked fuel line.
I'd also try a different mechanic.
I have very good luck with Stihl for my Husqvarna. HTH
