Here's an update... I got it apart and cleaned the throttle plate and the aluminum housing and everything I could see with carb cleaner. Put it back together. Put fresh gas in. Started it, and after a rough patch I was able to adjust the torx screw, which appears to be a choke spring tension...
I put fresh gas in it, and it started, but it's back to running rough again. Every few seconds it sounds like it's going to die, and a spring loaded linkage at the front of the motor seems to loosen about a quarter of an inch and then goes back to its original position when the engine comes back...
Thank you.. I'll try that. Meanwhile, I noticed that when I take the float assembly out and try to blow through the ridged gas input fitting no air can pass through it. I can't see any way to unclog it, because I don't see or feel any hole. Does that sound normal? I had the assembly out...
I have a Coleman 2500 generator with a 5 horsepower Tecumseh. it was running rough, but after I changed the oil, it was running perfect. I put it away for 2 months. got it out again started it... it was running rough. I took it apart cleaned the carburetor float assembly, put it back together...
