read it on the oil can, bottle, put 1 gal gas in first a marked clean gas can, and ad oil last watch the gas pump not the can, and stop at what amount of gas you need get 100 percent gas in all your trimmers ,blowers! // if the can you are going to use only has a small amount pour it out it might have water in it and that's another story. Rideau Canal Oil Gas Fuel Mix Tables and watch this neat video Christ The Redeemer!
Two-stroke oil with a 50:1 (Gas:Oil) mix ratio is required for the Husqvarna 125B leaf blower. Using the wrong oil or improper mixture ratio can drastically affect the performance of the leaf blower.
If it is a 4 cycle blower, you do not mix oil with the fuel....It takes straight Gas. there is an oil cap to put engine oil in crankcase, this only usually takes 2,3,4 oz. of oil. Sounds like your Spark Plug probably fouled out from having oil mixed in your gas. I would recomend changing your Spark Plug and put some Fresh GAS only in the blower, dump the old stuff out !!! You should be on your way Blowing in No Time !
Your manual (from Sears) states that your mix ratio is 40:1. You will need 3.2 ounces of Poulan "Pro" synthetic 2 stroke oil mixed in 1 U.S gallon of gas or you can mix 1.6 ounces of the oil in a half-gallon of gas. They suggest using the Poulan "Pro" brand synthetic oil. I do also. Synthetic oil significantly reduces wear, allows the machine to run cooler, and burns cleaner with less by-products and emissions. You can view a PDF file of your manual here:
Welcome to the wonderful world of 2 cycle engines. Your McCullough blower uses a fuel mix to lubricate the piston. You MUST mix 3.2 ounces of 2 cycle mix to every gallon (U.S.) of gasoline.
If you run straight gasoline through your blower, you will RUIN the engine in seconds!
The fuel mix ratio is crucial to the lifespan of the engine. DO NOT GUESS.......MEASURE !!
I would also encourage you to purchase a 2 cycle mix that contains a fuel stabilizer. Gasoline starts to degrade in as little as 60 days, and a stabilizer will allow your fuel to stay fresh longer.
Usually if you use the brand the 2 cycle recommends (their brand of oil) it's 4 oz. to one gallon of gas. If you use a generic brand they say mix it 6 oz to one gallon. Most will run fine on the 6 to 1.
Check for spark in the new spark plug, if you have spark clean the carb fully and try again. make sure you have correct mix of gas to oil and it is not old use fresh gas oil mixture. Good luck pal.
It's 40:1 but there are oil mixes out there now that you can buy that you mix with one gallon of gas and then it is safe for all 2-cycle engines...a real plus if you own multiple units with different mix ratios.
Your fuel-oil mixture has too much oil in it. The standard ratio is 40:1 which means one of the little bottles of 2-stroke oil (about 2.6 fluid ounces) is added to 1 gallon of gas. Homelite recommends a 50:1 ratio but 40:1 is better, at least in my opinion.
The last time you made the mix, did you pour the oil into the gas or did you pour the oil into a little bit of gas in the gas can, shake well and then fill it with a gallon of gas? The former can give you lots of smoke as well because it is not mixed thoroughly. The latter is the best way to mix because the agitation and the flow of gas mixes the oil better.
Other possible causes to this problem are: how old is the mix you are using? Did this mix sit all winter last and you sre using it now? If so, did you add some Stabil to the mix before storing?
Depending on your answers to the above questions, you can determine why you are getting so much white smoke.
My recommendation to you is to:
(a) Empty the blower gas tank.
(b) Mix a fresh batch of oil and gas in an approved fuel container.
(c) Pull the spark plug and inspect it, if it is black/sooty replace it.
(d) Pour the new mix into the tank and start the blower.
This should get rid of the excess smoke, if it doesn't, let me know here. Good Luck!
