I just bought a one man Earth Auger at a local auction. (power post hole digger). The thing is old, but for $5, I decided to give it a shot since these things are over $350 new. It has a Tecumseh 2 cycle engine - power head. After spraying carb cleaner thru all the carb ports, I got the engine to run but it's runs very rough. I think much of this has to do with the carb adjustments. The problem is that I dont know which screw does what or what the initial settings should be (other than what they were, which I wrote down).
It's a 3HP Tecumseh 2 cycle engine. There is a large screw and a smaller screw. They are next to each other. Does anyone know anything about adjusting these? I repair lots of 4 cycle engines, but am not very familiar with 2 cycle engines.
The initial settings that it had was approx. 2 1/2 turns on each screw.
Is there a standard meaning for small screw and large screw, or is this just this particular model?
An additional mention. This thing has no name or model number. Just says Tecumseh 3hp on the engine, so I am not sure if the whole tool is made by Tecumseh, or just the engine. This will make it real hard to ever get any parts or a manual for it. From the looks of it, I suspect it was made in the 1970's or 80's.
Thanks
