I have a 01 115 tlrs 2 stroke I just got. When it was tested during buying the engine started right up. 130 compression across the board as well. Once I got it home and tried to start, it was hard to start and wouldn't idle. I had to give continuous gas to keep going and it had that bogging sound. I figured dirty carbs so I proceeded to clean the carbs. I did find many clogged jets and almost a jelly in the bottom bowl. I also cleaned out the fuel filter and checked the fuel pump for any ethanol crystals. I also drained all the gas since it looked cloudy and brown. I put fresh gas in and installed a fuel water separator. Now it seems there is some kind of back pressure and gas will not get to the cylinders. I pumped the primer and could tell the carbs had fuel in them but the bulb felt odd like it had air pushing back on it. It didnt feel fuel hard. i would unhook and hear a pop of air escaping. I sprayed ether into the cylinders the motor fired but would die as soon as the ether was gone. What could be holding the fuel back from entering the cylinders? Some kind of vapor lock in the vac line? Any thoughts are much appreciated. thanks.
