No real damage will be done, just empty the gas out and re fill with chain oil, thats all you need to do.

I filled the gas tank in my chain saw with bar oil. Is there an easy way to remove the oil from the carburetor and get it started?

Dump out the bar oil and put in some pure gas and shake the saw to thin the bar oil. If it has a primer bulb push it a few time to flush the oil through. Dump this out and put in the proper mixed fuel and try starting.

I filled the gas tank in my chain saw with bar oil. Is there an easy way to remove the oil from the carburetor and get it started?

Hello. It's doubtful the bar oil has made it to the inside of the carburetor. Dump as much as possible out of the tank, disconnect the gas line from the carburetor and blow any oil in the line and filter back to the tank. Partially fill the tank with premix and briskly shake the saw to dilute the bar oil. Dump the bar oil pre mix solution from the tank and repeat. This will also clean the in tank filter and should be done at the beginning of the season.

My Homlite chainsaw will not start. There is fuel coming out of the of the bar. It ran for a while, maybe three or four small jobs. The saw will not start. Although I am no expert I did work for Magneto...

You stated that there is fuel coming out of the bar, If this is the case fuel has gotten into the bar oil tank. Drain the bar oil tank and the fill with bar oil then drain the fuel tank and fill with fresh fuel.

Need fuel mixture specs

50:1 is the fuel to oil ratio using a modern synthetic saw oil available at home centers, hardware stores, and saw dealers. Be sure to mix the fuel and oil in it's own container, and to shake the container thoroughly each time just before filling the tank to prevent oil starvation. Hope this helps!

Does it take regular gas, or gas and oil mix? 50 to 1 ?

50:1 mix in the gas tank and bar oil in the oil tank. Fill your oil when you fill the gas. Keep the chain sharp.

I put gas in the oil tank and the oil in the gas tank by mistake, started the saw , it ran for a few minutes then it serious???

Not likely. The gas in the oil tank can be drained and refill with bar oil - it might even help it feed more oil to the bar and chain as it would clean any deposits out! The oil in the fuel would just plug up the jets in your carburetor. You'll need to remove the tank and any housing over the carb, as well as the air filter. Blow compressed air into the fuel line to remove the oil from it and watch where it comes out in the carb. Now spray carb cleaner into the throat the oil came out using the red straw. It is possible you may need to remove the air / fuel mix screws on the side of the carb. If so, turn those screws clockwise, counting how many turns it takes to bottom out the screw - take your time, this is really important to get it to run when your done.Don't tighten those screws down - you may damage the seat which will affect the operation. Writing down the turns may help - it helped me!! Remove those screws and blast those ports with the carb cleaner and straw.Spray out fuel line again as well as the throat the oil came out in the carb. Remove and clean or replace spark plug. Doing it now will give the carb cleaner time to dry out. Install those screws, making sure you get them in the right positions and the right turns out by bottoming out the screws then turning out to the proper distance. Install tank, air cleaner, and shoot a 1/2 second blast of starting fluid into the cylinder before you install the plug - make sure you use starting fluid with lubrication so you don't bugger up the piston rings or cylinder wall. Install spark plug, fill oil tank, fill fuel tank with proper mix fuel, choke and start - you should be good to go.
Hope this helps!!

How much chan lubricant should be used and what is the grade of the oil

You want to buy Bar grade oil, it is sticky and stays on the chain, it will properly lube the bar and chain with a full tank o gas. People have used, used motor oil but this wears down the chain and gears from the micro sized filings in the oil so use clean bar oil to lube the chain correctly. also if the chain sprocket has a small hole in the tip of the saw you will need to buy a gear lube pump to keep grease in the gear at the tip of the blade. This should be lube each time you fill the fuel tank and once half way threw the tank of fuel to make the bar last longer. The bar oil is a special grade of oil and requires bar oil for it to adhere to the bar and the bar guides. Hope this helps and thanks for using fix-ya.

Gas oil mixture

The header says that it is an electric saw which would only require bar oil. A 2-stroke gas engine, however, does require fuel mixed with a modern saw oil at 40:1 ratio plus bar/chain oil in it's own tank as well. Always premix the fuel and oil in a separate can and shake well even before filling the saw. Hope this helps!
