I have a Husqvarna 36 air injection gas chainsaw 16 inch blade. I need help with the gas and oil mixture as I have bought it second hand and have no owners manual. thanks

What condition is your spark plug in?Is your filter clean?Is your gas-oil mixture correct? Is your gas fresh?Is your brake releasing?Is the blade and chain on correct?

With Husqvarna two stroke oil it should run at 50-1, with other two stroke oil run it at 25-1 as we do not know the quaility of other oils, always try to use Husqvarna oil.

this new gas is a carb killer you will need a new diaphragm for the carb and there is a little screan next to the needle and seat that can be cleaned. about a 5.00 repair if done right.. use marine gas

Good quaility two stroke oil designed for chainsaws ( not out boards ) and designed to run at 50-1

Any brand of 2-cycle oil for air cooled engines will work. Do not use outboard, snowmobile, etc. Sounds like the gas evaporated and the oil was left in the carb and clogged it up. You can try removing the air filter and spraying some gum cutter, carb cleaner or Sea Foam(my favorite) into the carburator. It will probably need to be diassembled and cleaned. Usually the hardest part of the job is getting the link and hoses unhooked.

Oil Mix Ratio:

Starting in the early to mid 90s Dolmar, Echo, efco, Homelite, Husqvarna, Jonsered, Makita, Oleo-Mac, Red Max, Ryobi, Shindaiwa, Solo, Spear & Jackson, Stihl and Tanaka all started recommending 50:1

• 1 gallon of premium fuel to 2.6 ounces of quality 2-cycle oil or
• 4 liters of premium fuel to 80 milliliters of quality 2-cycle oil.

McCulloch, Poulan & Wen recommend 40:1

• 1 gallon of premium fuel to 3.2 ounces of quality 2-cycle oil or
• 4 liters of premium fuel to 100 milliliters of quality 2-cycle oil.

Chinese chainsaws recommend 25:1.

The fuel to oil ratio is 50:1. Be sure to use a modern synthetic saw oil available from home centers, hardware stores, and saw dealers. Premix in it's own container with fresh fuel and be sure to shake the container thoroughly just before you fill the tank each time to prevent oil starvation. Hope this helps!

Oil Mix Ratio:

Chinese chainsaws recommend 25:1.

Thank You for using FixYa.

Get Chain lube for the chain oiler. Naturally, husqvarna recommends that you use "genuine husqvarna" oil for your mixture, I recommend a quality oil, doesn't have to be husky. Husqvarna recommends a 50:1 ratio, other manufacturers, of vertually all 2 cycle power equiptment use a 40:1 ratio. This mixture is slightly richer, but will not hurt your chainsaw. May produce a bit more smoke. Not sure what a 34 husky is...neither is Husqvarna, I visited the website and even tried to download a manual. Looked at every husky model, no 34.

40 to 1 is the ratio.
