cafoose 3,742 #1 Posted 3 hours ago I was mowing with my 520-HC and I noticed the oil light came on. I promptly added oil to the full mark and it seemed to have lost power and started missing. I checked compression and the front cylinder is 85 and the rear is 0. It still starts and no loud knocking like a broken rod. I did notice wet oil drips underneath but nothing like a vented block. I hear they're expensive and difficult to rebuild. Thinking of a possible repower. 22 HP predator is $950 and 16.8 is $450. Is there really much difference in performance between the two for just running a 48 inch deck? Any other options or suggestions? Share this post Link to post Share on other sites
