![]() ![]() The dogtag on the engine says 1589 Techumseh 8283, so slightly different than my mock up, but the only difference I can see is the angle of the carb is a little different and the drive shaft is a little different, but still with the integrated key, just closer towards the engine which will help with the alighnment. OK, here is where I stand, I picked up the snow thrower yesterday and pulled the engine. But I guess I will not know that until I get all the pieces together. Then comes the real question as to if the chain will even clear the frame. The only sprocket I could find which may fit is this one: the problem is for a sprocket to fit properly it needs a center home of 2 1/8 and a four bolt pattern of 2 9/16. Lastly the rear wheel is 10" so I would like to go as large as possible on the rear sprocket, somewhere between 7 and 8 inches. Third, what chain number should I use? I assume the #25 that came stock on the bike will not be sufficient. I assume there is no easy way to shorten the shaft and secondly what type of clutch would fit on the 5/8 shaft that has the key integrated into it. Secondly the drive shaft on the engine is longer than I would like and also has an integrated key in the shaft. ![]() Assuming this is the same engine as in the thrower does anyone have any info on it? It is the biggest thing that I can squeeze into the frame. I will be picking it up tomorrow but I do have a second non-working engine which I believe is the same model as the working one in the thrower. I also happened upon an old snow thrower with a Tecumseh engine. Another great source for the correct lubricant for an application is Castrol’s Oil Selector.I came across an old razor mini chopper and decided to convert it to gas. Always check your owner’s manual for the correct lubricant for your engine. Two-stroke engine oils are generally lighter, lower and ash and made to be consumed in two-stroke engines, so they do not last as long as four-stroke engine oils. Four-stroke engine oils should not be used in two-stroke applications (and two-stroke engine oils shouldn’t be used in four-stroke engines). Also, since two-stroke oils are consumed, the ash content of two-stroke engine oils are significantly lower and may contain a significantly different additive package than four-stroke oils.Īs with any engine oil, it is vital to use the correct lubricant for your engine. That means that the oil is consumed at a much higher rate than four-stroke oils (which are not consumed as part of the lubrication in a four-stroke engine). As previously mentioned, two-stroke oils mix with gasoline when it is used in a two-stroke engine. Two-stroke oils have similar additives and base oils than four-stroke oils, but there are some significant differences. Can I use 4 stroke oil in a 2 stroke engine? Since two-stroke engines are often smaller, lighter and simpler than four-stroke engines they deliver a higher power-to-weight ratio and are often used in smaller equipment applications such as lawn mowers and other garden equipment and also in small engine vehicles (scooters, jet skis, ATF’s and small outboard engines). The piston goes back down and exhaust valve is opened to release the spent mixture.The spark plug fires and ignites the gas/air mixture.The oil/fuel mixture is compressed and the intake valve closes to compress the gas.Oil and fuel are mixed in the compression chamber as the piston moves down the cylinder.Four-cycle engines operate in the following manner: As the compression occurs, a reed valve opens that removes the fuel/oil/air mixture and the cycle begins again.Ī key difference between a four-cycle engine oil and a two-cycle engine oil is that a four-cycle engine oil does not mix the fuel and oil. The spark plug fires and sends the piston down to complete the compression cycle. Fuel and oil are mixed with air and compressed, then pushed toward the spark plug. ![]() Two-cycle engines do not contain valves due to the engine mechanics of how a two-cycle engine works. Where four-cycle engines are commonly used in larger applications such as automobiles, motorcycle, boats and larger engine applications, two-cycle engines are often used in smaller engine applications such as lawn equipment and scooters. Two-cycle engines and four-cycle engines are both used in mechanical equipment, but the type of equipment determines the better engine to use. When using an oil for a two-cycle engine, it is important to use the correct two-cycle oil or else it could damage the engine due to the differences between a two-cycle and four-cycle engine.ĭifference between Two-Cycle and Four-Cycle Engines Two-stroke or two-cycle engine oils are special motor oils that are designed for use in two-cycle (two-stroke) engines. How Is Two-Stroke Engine Oil Different? Can I Use 4 Cycle Oil Instead? ![]()
