ML3 1,977 #1 Posted 5 hours ago Doing some pre snow maint/repairs on my Workhorse. Bervac all connected & working properly. Seems like when climbing even the slightest grade (my driveway is pretty flat but graded just enough to drain water) there's a noticeable loss of power. Worse with snowblower engaged. It does seem to possibly be running a bit rich so I may start by doing some carb adjustments? I know the hydro does & can take a while to really warm up. Im getting full range from the throttle. I believe with a load of snow in blower it will only make it worse. 2 Share this post Link to post Share on other sites
ebinmaine 74,831 #2 Posted 5 hours ago Do you use non ethanol fuel? Has the carb been rebuilt lately? Age of fuel lines? Share this post Link to post Share on other sites
ML3 1,977 #3 Posted 5 hours ago (edited) Always use ethanol free fuel. I replaced all fuel lines & filter as preventative maint. Prior owner took carb off & overhauled before he sold it to me. Starts up easily & seems to run fine but like I said definitely a noticeable loss of power with the slightest load. Edited 5 hours ago by ML3 1 Share this post Link to post Share on other sites
ebinmaine 74,831 #4 Posted 5 hours ago I'd start with the carb clean. Maybe download a manual and check / adjust the governor linkage. Share this post Link to post Share on other sites

Bill D 2,385 #7 Posted 5 hours ago (edited) Good compression on each cylinder? Any signs of leaking head gaskets? Is it firing on both cylinders? What happens if you pull one plug wire? Does it die or stay running? I've seen that engine run surprisingly well with loose heads and leaking head gaskets. Also check for intake manifold leaks and a possible clogged exhaust. I have one here with loose baffles in the muffler. They can also suffer from loose valve seats like Onans. Edited 4 hours ago by Bill D 3 Share this post Link to post Share on other sites
Handy Don 14,818 #8 Posted 4 hours ago Some years ago on another brand mower with a B&S engine it was weak under loads. I tied a string directly to the throttle so I could give it a pull when I thought the governor shoulda been kicking in. Get on the hill, pull on string, throttle opens more, engine adds power. Governor linkage was in the wrong hole on the throttle actuator. (And yeah, it was me that put it together wrong in the first place) 1 Share this post Link to post Share on other sites
