What is fuel to oil ratio for PS-05744? - Homelite Garden

24/1 is the correct ratio. I certainly wouldn't go 50/1 but you could split the difference with a good synthetic.

What is the mix ratio for a Johnson outboard motor?

Any Johnson outboard motor built since 1964 requires a 50/1 fuel ratio. Motors built prior to that date require a 32/1 ratio, with the exception of a few fishing motors built prior to 1955 that use a 16/1 ratio.

What is the mixing ratio for a Johnson outboard motor? - Mvorganizing.org

need the year of manufacture as some 2 stroke units have oil injection that automatically mixes the oil in the correct ratio for engine rpms otherwise it is 50:1 ( 50 parts fuel to 1 part oil)
oil requirements --certified tc-w3 2 stroke outboard oil ---not ordinary engine oil
reference
google --type in mercury outboard oil to fuel ratio

HELLO THERE AND THANK YOU FOR CHOOSING FIXYA
From Poulan website:
The fuel-oil mixture ratio for all Poulan two-cycle products is 40:1. You can obtain this ratio by mixing 3.2 oz. of oil with one gallon of regular gas. If you have other brands of equipment that require different fuel/oil ratios and you don't want to mix separate fuel cans, you should use the lowest numerical ratio. For example, if you have products requiring 40:1, 50:1, and 32:1 ratios you should use the 32:1 ratio for all products. This may cause slight smoke increase in the exhaust in the 40:1 and 50:1 products due to more oil in the fuel, but it won't damage either of the engines.

Oil leaking from your powervalve hose could be caused by a few things mate. First thing to check is your air filter.A blocked(due to dirt)air filter is the most common cause of a rich running 2 stroke. If you have cleaned it recently, be sure you haven't over oiled it. if your not sure, after applying the oil wrap it in a clean cloth & squeeze it (don't wring it like you would clothing) this will remove any excess oil. I recomend a proper air filter oil(from a motorcycle shop) but don't recomend the "no toil brand" of airfilter oil unless you clean it out after every race( if you race your bike),grease the seal & replace the filter in the bike.If you don't have propper air filter oil you need to use a thick oil otherwise the oil will sink to the bottom of the filter.
Next suggestion is your oil fuel ratio. If you are using one of the ultra expensive synthetic or semi-synthetic oils try leaning its ratio to 40:1. Be sure to very regularly check your sparkplug colour after doing so. It should be a tan colour & not wet,black & oily.Please be very vigelant with you plug checking as if you go too lean a seizure can occur so only try this if the other checks prove ok.
Another cause could be that the powervalve seal(behind the cover) has popped out letting the oil/fuel out. Replace/reposition the seal & this should help.
Another suggestion is to check your gearbox oil. Is it dissapearing yet you can't find a leak? This symptom indicates you have a blown crank seal. If so it is allowing gearbox oil to enter the crankcase & is richening your oil fuel ratio due to this fault.
Finally it could be running just too rich ie delivering too much fuel/oil mixture. This is commonly expressed by the symptom of a very wet & oily muffler.To rectify this you need to reduce the size of the main jet in the carburettor. After diong so you must carry out regular plug checks like you did for adjusting the oil/fuel ratio.Care again must be taken as to not seize the engine.
Hope this helps regards

PS look for my tips on 2 stroke mx'ers comming in the next few weeks

100 ml of 2cycle oil to 4000 ml of fuel..Which is 40/1 ratio
100 ml of 2cycle oil to 5000 ml of fuel.. which is 50/1 ratio

4 o/z is 118.29411875006815 ml to 1 gallon of fuel (3.79 litres or 3790 ml) Which means 32/1 ratio...I find that to confusing,so it is easier to say 100 ml of oil to 3200 ml of fuel ===32/1.

FUELING ENGINE
WARNING: Remove fuel cap slowly
when refueling.
HELPFUL TIP
To obtain the correct oilmix
ratio, pour 3.2 ounces of
2--cycle synthetic oil into
one gallon of fresh gas.
This engine is certified to operate on unleaded
gasoline. Before operation, gasoline must be
mixed with a good quality synthetic 2-cycle
air-cooled engine oil designed to be mixed at a
ratio of 40:1. Poulan/Weed Eater brand
synthetic oil is recommended.Mix gasoline and
oil at a ratio of 40:1. A 40:1 ratio is obtained by
mixing 3.2 ounces (95ml) of oil with 1 gallon (4
liters) of unleaded gasoline. DO NOT USE
automotive oil or marine oil.

Hello mcguilmd:

>>All Two Stroke Engines will use a 50 to 1 Ratio using Today's Two Stroke Oils. I once had an Old Chainsaw probably from the 1950s, maybe Earlier 70s that had a sticker on it that said to use a 25 to 1 Fuel/Oil Ratio, but that would have been using Two Stroke Oils of the Time Period the Chainsaw was Manufactured. I was having a Problem with Oil Coming Out of the Muffler and Started Decreasing the Oil in the Gas. I Reduced the Oil Until it was a t a 45:1 Ratio and Decided to be Safe, I would Use a 40:1 Ratio Mix. In that Chainsaw I used 50 to 1 Ratio with no problems. Today's Two Stroke Oils compared to Yesteryears are more Efficient at Lubricating. It is like comparing Today's Synthetic Motor Oil to Motor Oils of Decades ago. All the Equipment I use in Landscaping, anything from a Weed Eater, Leaf Blower, Chainsaw, Hedge Trimmer, use 40 to 1 ratio, and I use all types of makes and models, Stihl, Homelite, Husqvarna, Shindaiwa, and Echo, Sears. I mix up a 5 Gallon Fuel can and use it in all of the Equipment for my Customers and for my Landscaping. I like my Fuel/Oil Ratio a Little Heavy, so I use a 40:1 Ratio. The Following was Copied and Pasted here from and MTD E-mail to me when I Asked for the OEMs Suggested Mixture for this Unit. The mixture, as described by the engine manufacturer, is a 50:1 ratio when using the approved types of 2-cycle engine oils.
50:1 ratio is a mix consisting of 2.5 ounces of 2-cycle oil per 1 gallon of gasoline.
The 2-cycle oil used should be approved and have one or more of the following specification titles: NMMA TC-WII, TC-W3, JASO FB, or JASO FC. NOTE: If unsure of the 2-cycle oil specifications, or the oil is not approved, use a 32:1 fuel to oil ratio. This ratio consists of 4 ounces of oil per one gallon of fuel.
NOTE: Always mix 2-cycle fuel oil and fuel in an approved gasoline safe container prior to filling the engine. Make sure to use a separate gas can for this 2-cycle fuel mixture and label it accordingly. Keep in mind that the fuel capacity of these engines normally is less than a gallon, therefore you will have to use this extra oil mixture for multiple fuel fills. Adding a fuel stabilizer will also help to increase the shelf life of fuel.
>>I Suggest Using a 40:1 Ratio and if Oil Starts Coming Out the Muffler then go to a 50:1 Ratio.
Please, Do Not Hesitate, If I Missed Something or you Hit a Snag or this Does Not Correct the Problem, I am Here if You Require More Assistance.
Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Be Safe and Be Happy. Thanks.

Good Luck

Respectfully

40 to 1 is the ratio.
