I have a 2012 Husqvarna LGT 2654 that I bought a few months ago with 22.4 hours on the clock. It seemed to run fine and being that unused I did not test it real hard. Anyway, the problem that I have is that it bogs down and starts blowing black smoke. Sometimes it's while mowing grass that is a little on the tall side and sometimes it just starts bogging down and smoking for no reason. I have to stop and wait for it to get over it's chugging and shaking before I can continue.
A friend told me that these motors can have issues with the fuel pump pushing too much fuel so I installed a ball valve on the vacuum line going from the crank case to the fuel pump. That seems to be of no help. If I turn it off, the carb runs out of fuel and it stalls (as I would expect). If it's open just a little, the mower runs like crap.
Also...This mower sucks gas like there is no tomorrow so it is obviously running rich.
Help!
