    Engine loses power

    My 8N, front mount distributer, 6V stumbles on the slightest uphill and will die if the incline is steep enough or long enough. Nothing changes on a downhill. I recently put a new carb on it since it sat for some years as well as a new fuel line. My first inclination is/was the governor and when...

    Valve adjustment

    Does anybody know where to find Aaron's instructions for setting valves? All the links that I've found go to All States Ag Parts and they don't show or list any how-to videos. They sure were easy instructions.

    Head bolt torque sequence

    When I first installed a new head gasket on my YM240D, I was able to find a written specific sequence of head bolt torquing that was very useful. It showed the 3 torque stages, the specific nut sequence for tightening, and the number of re-torques and at what times. Is there such a thing still...

    Losing spark

    Back to where I was before I jammed the over-run coupler. Ran the 8N, original 6V Front mount for about an hour yesterday with out problems. Thought I finally had the bugs worked out. Ran it today, starting hearing a little missing and by the time I got it home had a definite miss. Shut it off...

    8N Over-run coupler

    Have an 8N with a broken over-run coupler. It doesn't allow my brushhog to freewheel when I disengage the clutch. Any ideas on how to get it off? I assumed from looking at it you just removed the set screw and the Zerk fitting and pounded out the pin with a punch? I've beat on the end of the pin...

    Exhaust popping, losing power when hot

    Been trying to revive an old 8N after sitting for 7 years. 6 volt, with front mount distributor. Have replaced a fair bit of parts, new gas tank, fuel line, sediment bowl, and all 3 screens. Passes fuel flow test from carb without problem. New points, condenser, distributor, square coil, and...

    Engine Compression

    Having trouble starting a Yanmar 240D. Used it and parked it. Now getting lots of white smoke but doesn't even make a pop even with a block heater making it warm. Last try I decided to adjust the valves and I was able to put a 8" wrench on one of the front pulley nuts and turn the crank fairly...

    Determining engine temp

    A question that may seem simple but I can't seem to find an answer. Yanmar 240D (2 cyl. diesel), at what temp is it considered over-heating, and more importantly, where do you take that temp? I only have the idiot lights. I ran the tractor for 30 minutes in about 95' for 20 minutes and felt that...

    Mower PTO shaft won't come off

    I broke a couple u-joint bearings on my mower PTO shaft. Thought it would be more convenient to just replace the shaft but I cannot figure out how to remove the old shaft from the mower. I assumed that removing the shear bolt and the retaining ring would allow it to slide off but thats not the...

    Low compression

    Was given a 240D that had been started a few times using starting fluid. Compression is really low, as might be expected. Ive used it during the last 2 summers getting it started by using a block heater for about an hour to get it to starting temp. It has good power and not much blow by after...

    Stopping transmission to engage

    This will probably be a stupid question, but when I get on and off my tractor to do something, putting it back into gear always causes the transmission to slightly grind since the trans spins while I'm off. It's pretty minor but any idea how to get the transmission to synchronize when I get off...

    How do you submit a support ticket?

    I have been looking for the support ticket submission area and can't seem to find it. I tried the "Help" on the Home page but it takes me to the FAQ's and there isn't a submission area. I did a forum "search" without results. I am unable to post any more photos (using the same technique as the 3...

    240D RPM's

    I finally hooked up my mower (5') and drove to around for a bit to check for problems. According to the manual the mower should be running at 540 rpm's with the engine operating in the neighborhood of 2200 rpm's. In driving it around the engine was running at about 1900-2000 rpm's and everything...

    Checking temp

    I imagine this has been asked multiple times before but I found it a little tough to phrase the question for the search. My Yanmar 240D doesn't have a temp gauge (although I am going to install one) so I purchased a laser temp gauge. Where on the engine does one check for the actual operating...
