I found a pretty nice 520 with electric start. not sure if paddles need replacing. what is the best way to tell? when running are they supposed to scrape the ground? these dont. I replaced the paddles on my other 520 and measured the new with the old and they were exactly the same width but I noticed a nice improvement with the new paddles. so dont understand.It's tough to tell w/o seeing the profile of the augers, which is the dead giveaway. But this looks right and sounds right; the part numbers are correct. The fact that they mention the nuts are not included makes me think it is authentic...the Honda kits do not include them either (which I always found odd). An email to the company would clarify for sure.
I've got hundreds of those darn bolts now LOL.
These paddles on the 520 I just got dont seem to be worn much. thinking of replacing anyway to have a good back up.
thanks in advance.
