Well, I just ordered a new $17.88 carb from Amazon for my Troy Bilt with Briggs 550EX "no start" engine. We'll see what happens! Also, I switched over to ethanol-free fuel after the last trip to the small engine guy & that did not fix my yearly spring no-start problem, AND I do use Sea Foam every fall. (I hardly ever use the mower)
This thing has been nothing but a POS ever since it was new. I maybe have 6 hours on it.
Well, I just had time to install the new Chinee carb & first pull it started right up, but it runs at a low-ish RPM & it surges. There is some kind of solenoid & I'ma wondering if this is the cause of the surge? You can watch the linkage moving which causes the surge. There is no throttle control with this mower - it's either full on or off. This thing is SUCH a piece of crap!
