Q: WHAT IS THE FUEL/OIL MIX RATIO FOR A 2-CYCLE ENGINE?
# A: Per Tecumseh Products engine specifications, the Fuel/oil ratio
should be 40:1 (3 oz oil to one gallon gas) using a standard two cycle
engine oil. We also recommend using a no-smoke 2 cycle oil. (Sold in our
On-Ice Store) DO NOT USE METHANOL. Make sure to use winter formulated
(usually available November – April depending upon manufacturers) premium
unleaded gasoline-91 Octane (DO NOT USE WHITE GAS) for best engine
performance. DO NOT USE A MULTI-VISCOSITY OIL. Recommended brands of oil:
StrikeMaster’s No-Smoke, Two-Stroke Oil or any brand name, air-cooled, two
cycle engine oil such as Tecumseh, Homelite, Steele, etc. (mix oil to
Tecumseh’s specifications, not the oil manufacturer’s.
Since your seeing two difference mixture ratios, I would give StrikeMaster a call directly on Monday. Phone: 763.263.8999
Here’s how to fix the excessive oil out the the exhaust.
PS I’m a Klotz type a guy….love the smell of the stuff..just as good a amsoil and a bit less expensive.
Q: WHAT IS THE BLACK STUFF RUNNING OUT OF THE MUFFLER ON MY 2HP AUGER?
A: 2-cycle engined require mixing 2-cycle oil with unleaded fuel (in the fuel can before filing the tank on the auger). Some of the oil does not always burn off entirely and will secrete out the muffler. If you are noticing that there is excessive oil secretions from your muffler or that the spark plug is getting “gummed up”, the fuel /oil mixture is most likely mixed too rich (too much oil). Add 1-2 oz. of unleaded gas to lean out mixture (do not add directly to your auger’s fuel tank). Make sure to use winter formulated unleaded gasoline for best engine performance.
