This is a Stihl Concrete Saw, TS400.....it's the first cousin to a heavy Stihl Chain saw, so I though some posters might have some ideas! I'm guessing the same carbs might be used in lots of other saws. (I don;t have the carb # yet)
It is 3.9ci, and has a 1.93" bore and a 1.34" stroke, and it makes a lot of power when it runs!
I'm sure it's dried corn in the fuel. I've thoroughly cleaned this carb, but it still won't start except on starting fluid for a few seconds. (yes, please don;t tell me about starting fluid, because I know )
I've cleaned many dozens of 2 cycle carbs including pulling the needle valves.
The only thing I'm unsure of on this one is there is a flat brass round fitting under one of the 4 screw end covers. The flat brass is round like a circle, maybe 3/8" diameter, and it has a hole in the center.
I've liberally sprayed carb cleaner there, and can't tell if it's getting through or not. I don;t have a wire that small for probing, as it's a real small opening.
Anybody seen this flat brass fitting ins a Tillotson carb on any Stihl unit, and if so, have ideas of how to check it
Other ideas?
