Broadmoor 728

Recommended Posts

Guest mjb20
Several years ago I purchased a Boadmoor Simplicity 728 with a 8 HP B&S engine which has done fine up until this season. The problem is the engine runs fine with full throttle and no choke. As it warms up, it needs more and more choke to stay running. Eventually it sputters out. I have drained the old gas, replaced the spark plug, and took down the carb and cleaned it up, but the problem persists. Any thoughts out there??? mb

Could be a leaky head gasket. If the gasket is leaking, you will need to replace it. They have small dimples in them, and once you get oil and carbon in thsed, the gasket will not re-seal even if you tighten it. You may also want to check your valve clearance. Rod H.

Had the same problem you are haveing on several occasions. Easy to miss.too. Lparky

        Over a year ago, you answered a question I had about the tool bar for my FDT. In your reply dated Dec 31, 2019  you said the spacer, part #16, goes in the bar to allow for up and down depth adjustment. does this mean the bolt has to be tightened at whatever depth desired or does the bolt slide up and down, allowing the lower hitch to free float?
         If it is tightened so the lower hitch and the bar are rigid, then is the depth to be controlled by the shoes? Or by the lift handle?
        Is there any kind of user directions for the tool bar? The Outdoor Power Manual basically shows how to assemble the bar but not how to use it
