Inside the Husqvarna 550XP
« on: July 19, 2012, 10:18:22 pm »
Little brown truck showed up today.  Going to be tearing into a 550XP (mini 562XP really).

First things first, a stock video.

They added a diagnostic port in a more convenient spot.  No more prying the carb around to access it.

Carb rebuild time on these autotune 550 545 555 562 560. Do we just buy a kit and install like we can do easily on other carbs?
