725 wired up

Recommended Posts

well today and yesterday I got the 2 725's wired up but i only have 1 S/G setup at this point. so when i checked the compression on them i had to pull it from one to the other and one was in the mid 30 and the other was about 50 is this good or not goods since i have not built the carbs for them yet. and dont want to spend the money on it if they wont have the power to them no more . and i was thinking if they should be replaced i would put a 10hp kohler in the one and wait it out for orginal one to show up on ebay. But to drop the kohler in it I know I have to cut the frame and cant seem to run across what way the tringal should be cut and the dim. of it. What do you guys think I should do ???

?Bryan. When you were checking compression did you have the throttle plate in the carb in the wide open position? You will get a false reading if the engine can't suck in enough air to compress. Your readings seem low. Squirt a little oil in to the cylinder;turn over a few times and then check compression at wide open throttle. Let us know how you make out. B10Dave^

        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
